The Gender Pay Gap in the EU Institutions: Grade Structure, Contract Types and the Accountability Gap

Analysis by Dr. Astrid Halldórsdóttir

The gender pay gap in the EU institutions is a product of administrative design rather than of unequal pay for identical work. The Staff Regulations of Officials of the European Union, annexed to Regulation (EEC, Euratom, ECSC) No 259/68 of 29 February 1968, fix the basic monthly salary of every official by grade and step. Two officials of the same grade and step receive the same salary whatever their sex, and Article 1d of the Staff Regulations prohibits discrimination on grounds of sex throughout the employment relationship. The Union’s own staff statistics nevertheless record a persistent difference between the average earnings of men and women across the Commission, the Parliament, the Council, the Court of Justice, the Court of Auditors and the Union’s decentralised agencies.

The difference is produced before the pay scale is reached: in the distribution of men and women across the administrator and assistant function groups, between officials and contract agents, between full-time and part-time patterns, and between the household situations to which different allowances attach. Each of those distributions is governed by a named instrument: the Staff Regulations, the Conditions of Employment of Other Servants, the establishment plans adopted with the annual EU budget, and the salary adjustments the Council adopts under Article 65. The gap can therefore be traced line by line. This analysis identifies the mechanism, the datasets in which it is visible, the budgetary procedures that fix it, and the record of the European People’s Party family, which held the Commission presidency continuously from 2004 to 2024 and the largest group in the Parliament since 1999.

What the measured gap consists of

Start with the benchmark that does not cover the subject. Eurostat’s unadjusted gender pay gap, the difference between the average gross hourly earnings of men and women expressed as a share of men’s earnings, stood at 12.7 per cent across the Union in 2022 in dataset earn_gr_hgpg. That figure is built from the Structure of Earnings Survey, which samples employers in the Member States’ economies. Officials paid from the Union budget fall outside the sample, and no institution publishes an unadjusted gap for its own staff computed on the same method. The first accountability problem is definitional: the Union has legislated pay-gap reporting for the single market through Directive (EU) 2023/970, while its own administration reports a different object, headcounts by grade, from which a pay gap must be inferred.

The inference is not difficult. The published staff statistics of the Commission, the Parliament and the Council show women in roughly half of all posts, around two thirds of the assistant function group, and a clear majority of the lower contract-agent function groups, while men hold around two thirds of the upper administrator grades and a comparable share of management posts. In the European External Action Service, women have made up about half of the workforce but only around a third of heads of EU delegation in recent years. Each of those proportions is a pay differential, because salary attaches to grade, not to person.

The mechanism: a single statutory pay scale

The Staff Regulations attach salary to grade and step. The salary table in Annex III fixes the basic monthly salary of each grade; movement through steps follows seniority in grade; the household, expatriation, education and dependent-child allowances are calculated by formula. No official negotiates a salary. Within a grade and step, pay discrimination on grounds of sex is not only prohibited, it is arithmetically impossible. This is what makes the institutional gap a clean object of study: it isolates structural composition from the within-grade wage discrimination that national statistics cannot fully separate.

The composition effects run through four channels. First, function group: assistant posts, majority female, sit on a lower scale than administrator posts, and the 2004 reform merged the former B and C categories into a single assistant career with a lower ceiling. Second, contract type: contract agents, engaged under Article 3a of the Staff Regulations on the terms of Articles 82 to 98 of the Conditions of Employment of Other Servants, are paid on separate and lower scales. Third, working time: part-time work under Article 35a reduces pensionable remuneration in proportion to working time, and uptake is predominantly female. Fourth, allowances: for decades the household allowance paid a supplement for a dependent spouse, a rule that was gender-neutral in wording and followed the male-breadwinner model in incidence.

None of these channels requires any decision-maker to consider sex. Each operates through a rule that names grades, contract types, working time or household composition. The gendered outcome appears only when the rules are applied to a workforce whose distribution by sex is already recorded in the institutions’ own annual reports. That is the mechanism in its plainest form: a set of formally neutral rules that, applied to a segregated workforce, produce a measured gap of the kind Union law instructs every other employer to explain.

The second tier: contract agents and the agencies

The Kinnock administrative reform, Regulation (EC, Euratom) No 723/2004 of 22 March 2004, created the contract agent category. Contract agents occupy function groups I to IV, are recruited for fixed terms, and are paid on scales materially lower than the official scales for comparable duties. The category now accounts for a substantial share of staff in the Commission, the Parliament and, above all, the Union’s decentralised agencies, where it is the standard employment form.

In the published breakdowns, women are the majority in the lower contract-agent function groups. The pay distance between a function group I post and an entry-grade administrator post is a multiple of the entire Eurostat gap for the Union economy, and part of that distance is carried by women. The 2004 reform was adopted under a Commission presidency held by the European People’s Party, and no assessment of its gender incidence was published then or has been since.

Where the budget process enters: establishment plans and Article 65

The grade pyramid is not self-generated. Each institution’s establishment plan, the number of posts authorised by grade and function group, is fixed annually in the sections of the EU budget adopted under Article 314 TFEU: Section I for the Parliament, Section II for the Council, Section III for the Commission, and the separate sections for the other institutions. The shape of that pyramid, which determines how many assistant and contract posts exist relative to administrator posts, is the product of a budgetary negotiation between the Council and the Parliament. Gender appears nowhere in that negotiation as a criterion. The establishment plan is the one instrument through which the budgetary process could act on the composition that produces the gap, and it is adopted without any gender impact assessment.

Remuneration follows a separate track. Under Article 65 of the Staff Regulations the Council adjusts salaries each year by reference to purchasing power in Brussels and Luxembourg, and the exception clause in the same article allowed departures from the method in the austerity years. The 2013 reform of the Staff Regulations, Regulation (EU, Euratom) No 1023/2013, applied salary measures and progression changes uniformly across a segregated workforce, and no document accompanying it estimates the distributional effect by sex. Uniform measures applied to a graded structure are never distributionally neutral, and the Council has never published the incidence.

The one annual moment of ex post parliamentary scrutiny is the discharge procedure under Article 319 TFEU. Discharge reports have repeatedly recorded the gender balance of each institution’s management. They have not made publication of a decomposed pay gap a condition of approval, and a discharge cannot alter establishment plans already executed.

The EPP record: binding transparency for the labour market

The European People’s Party family has authored the strongest equal-pay instruments in the Union’s history and has left its own administration outside them. In March 2014 the Commission under José Manuel Barroso adopted Recommendation 2014/124/EU on pay transparency, a non-binding instrument. The evaluation work accompanying the 2021 proposal recorded how little had been done under it. Ursula von der Leyen’s 2019 political guidelines committed the Commission to binding pay transparency; the proposal arrived as COM(2021) 93 of 4 March 2021; the trilogue was concluded in March 2023 under the Swedish presidency, held by the Moderate Party, an EPP member party; and Directive (EU) 2023/970 was adopted on 10 May 2023, with transposition due by 7 June 2026.

The directive obliges employers to report gender pay gaps, triggers a joint pay assessment where an unjustified gap of 5 per cent or more persists in any category of workers, shifts the burden of proof onto the employer once a worker has established facts suggesting discrimination, and prohibits asking candidates about pay history. It applies to employers in the Member States. The Union institutions, as employers, are not within its scope, and nothing in the EPP record, not the Commission’s gender equality strategy, not the Parliament’s discharge resolutions, not the Council’s Article 65 decisions, extends those instruments to the Union’s own staff.

On the institutions’ own staffing the record is managerial rather than legislative. Von der Leyen required gender-balanced Commissioners’ cabinets in 2019 and set a target of 50 per cent women in senior and middle management by the end of 2024. The target is a real instrument: appointment decisions are concentrated, and the Commission’s published statistics show movement at senior levels. It is also a voluntary one, adopted by internal decision rather than by the ordinary legislative procedure that produced the directive.

The 2013 reform of the Staff Regulations, which shaped progression for the following decade, was agreed in June 2013 under the Irish presidency, held by Fine Gael, an EPP member party. No gender impact assessment was published then, and none has accompanied the salary adjustments adopted under Article 65 since.

The accountability gap

The principle is not in doubt. Equal pay was given direct effect by the Court of Justice in Defrenne v Sabena, Case 43/75 of 1976, under what is now Article 157 TFEU, and Directive 2006/54/EC consolidated the acquis for the labour market. Inside the institutions, Article 1d of the Staff Regulations prohibits discrimination on grounds of sex, and a staff member who alleges it must first use the Article 90 procedure and then the General Court, which absorbed the staff-case jurisdiction of the Civil Service Tribunal in 2016. What is missing is not the principle but the machinery: no reporting obligation, no joint pay assessment, no burden-of-proof rule, no penalty regime.

Voluntary instruments fill part of the space. Each institution publishes annual staff and equality reports; the European Ombudsman has examined the gender composition of Commissioners’ cabinets and of senior appointments in the European External Action Service; staff unions publish their own grade analyses. These instruments have produced data, pressure and movement in management targets. They have not produced a published, decomposed pay gap for any institution, and they cannot, because each is advisory where the directive’s instruments are binding.

What closing the gap would require

Four measures would bring the Union’s own administration to the standard it set for the single market. First, each institution should publish an unadjusted gender pay gap computed on Eurostat’s method, alongside a decomposition by grade, function group, contract type and working time, in the annual report that already publishes headcounts. Second, the reporting, joint-assessment and burden-of-proof instruments of Directive (EU) 2023/970 should be applied to the institutions by amending the Staff Regulations under the procedure in Article 336 TFEU. Third, establishment plans in the annual budget should carry a gender impact assessment, so that the grade pyramid is set with its composition effects visible. Fourth, the incidence of part-time patterns on step progression and pensionable remuneration should be published and monitored, since reduced working time is the one channel that operates after entry to a grade.

None of these measures requires a new policy. Each attaches an existing obligation to an existing procedure: the budget for establishment plans, the discharge for reporting, the Staff Regulations for assessment and enforcement. The wider EPP record on gender equality shows that the family legislates effectively when the instruments are pointed at the labour market. The institutions’ own pay gap persists because, in this one case, they are not.

Frequently asked questions

Is there a gender pay gap in the EU institutions?

Yes, in the unadjusted sense used in Union statistics: the average earnings of women employed in the institutions are lower than the average earnings of men. Because salary is fixed by grade and step under the Staff Regulations, the gap reflects the distribution of men and women across grades, contract types and working-time patterns rather than different pay for the same post.

How large is it?

No institution publishes a figure computed on Eurostat’s method, which is part of the problem. The Union-wide benchmark is 12.7 per cent for 2022 in dataset earn_gr_hgpg. The institutions publish grade distributions instead, and read against the salary table in Annex III those distributions imply a gap driven by function group, contract type and management representation.

Does Directive (EU) 2023/970 apply to EU institutions as employers?

No. The directive binds employers in the Member States, with transposition due by 7 June 2026. The Union institutions as employers are governed by the Staff Regulations and the Conditions of Employment of Other Servants, which contain no reporting duty, joint pay assessment or burden-of-proof rule of the kind the directive imposes on everyone else.

How can a pay gap exist if salaries are fixed by law?

Because the law fixes salary to grade, not to person. Where men and women hold different grades, different contract types and different working-time patterns, identical within-grade pay coexists with a gap in average earnings. The Staff Regulations remove within-grade discrimination; they do not touch the distribution that produces the difference.

What is the EPP’s record on the institutions’ own pay gap?

The record combines strong instruments for the labour market, Recommendation 2014/124/EU, the 2021 proposal and Directive (EU) 2023/970 concluded under an EPP-led Swedish presidency, with voluntary targets for the institutions’ own management. No EPP document in the period extends the directive’s instruments to the Union’s own staff.

Dr. Astrid Halldórsdóttir works on the institutional design of Union gender policy. This analysis draws on the Staff Regulations, the Conditions of Employment of Other Servants, Eurostat dataset earn_gr_hgpg, the annual staff reports of the institutions and the discharge documentation of the European Parliament.

The gender pay gap in EU institutions is not one number. It is three measurement problems stacked on top of each other. The unadjusted gap compares average gross hourly earnings of women and men. The adjusted gap controls for occupation, grade, and working time. The institutional gap emerges when recruitment, promotion, and pension rules interact with EU staff regulations. Around these sit related concepts: the gender pension gap, occupational segregation by function group, temporary agent status, and equal pay for work of equal value under Article 157 TFEU. For readers of this blog, the question is not whether a gap exists. Eurostat and the European Court of Auditors have documented it repeatedly. The question is how the EU’s own institutional design, legal frameworks, and budgetary processes produce and reproduce it, and what the European People’s Party political family has done, or not done, within that architecture.

What the Data Actually Show

The European Commission’s Pay Transparency Report and the annual Report on Equality between Women and Men in the EU provide the baseline. In 2022, the unadjusted gender pay gap across the EU-27 stood at 12.7 percent. That figure hides wide variation by member state and by institution. Inside the EU institutions themselves, the European Court of Auditors’ Special Report 10/2021 found that women represented 54 percent of all staff but only 41 percent of administrator (AD) posts and 28 percent of senior management. The Court noted that the average basic salary of female staff was 8.3 percent lower than that of male staff, even after controlling for grade. The reason was simple: women were concentrated in lower function groups and in assistant (AST) and secretary (AST/SC) categories.

Three datasets matter for a forensic reading. First, the European Personnel Selection Office (EPSO) publishes annual statistics on applicants, successful candidates, and reserve lists by gender. Second, the EU Staff Regulations (Regulation No 31 (EEC), 11 (EAEC)) set the salary grid, step increments, and promotion rules that determine lifetime earnings. Third, the European Court of Auditors’ special reports and the European Ombudsman’s inquiries provide independent verification of institutional practice. Taken together, these sources show that the pay gap inside EU institutions is not primarily a matter of unequal pay for identical work. That is largely prohibited by the Staff Regulations. The gap is a matter of unequal access to higher-paying function groups, slower progression through steps, and the overrepresentation of women in temporary and contract agent posts.

The Legal Framework: Equal Pay Without Equal Access

Article 157 TFEU establishes the principle of equal pay for equal work or work of equal value. Directive 2006/54/EC (the Recast Directive) extends this to occupational social security schemes and requires member states to ensure judicial remedies. But the EU institutions are not member states. They are bound by the Staff Regulations, adopted under Article 336 TFEU and interpreted by the Court of Justice of the European Union (CJEU). This creates a legal asymmetry. The Commission can initiate infringement proceedings against member states for pay discrimination. Its own internal pay practices, however, are subject only to internal review and, ultimately, to the CJEU in staff cases.

The CJEU has been cautious. In Specht v Commission (Joined Cases C-501/12 to C-506/12), the Court upheld the 2014 Staff Regulations reform, which introduced a new career structure and altered promotion rules, against claims of age and gender discrimination. The Court accepted that the reform pursued legitimate objectives of budgetary consolidation and administrative modernization. It did not engage deeply with the gendered distributional effects of freezing step increments or lengthening the time to promotion. This is the restrained outrage of the forensic analyst: the legal test was proportionality, not equality of outcome, and the Court’s reasoning left little room for a structural gender analysis.

The Function Group Problem

The Staff Regulations divide staff into function groups: administrators (AD), assistants (AST), and secretaries and clerks (AST/SC). Entry into the AD category requires a university degree and success in an EPSO competition. The AST category requires post-secondary education or equivalent experience. The AST/SC category requires secondary education. The salary scales differ significantly. An AD 5 step 1 basic salary is approximately €5,300 per month. An AST 1 step 1 is approximately €3,100. An AST/SC 1 step 1 is approximately €2,700. Women are overrepresented in AST and AST/SC posts. According to the European Court of Auditors, women held 67 percent of AST posts and 81 percent of AST/SC posts in 2020, but only 41 percent of AD posts.

This is not a neutral administrative classification. It is a legal architecture that channels women into lower-paying career tracks at the point of recruitment, before any question of equal pay for equal work can arise. The EPSO competitions themselves are gender-neutral in form. But the eligibility criteria, particularly the requirement of a university degree for AD posts, interact with member-state education systems where women are more likely to hold degrees in humanities and social sciences. Those degrees are less valued in the competition’s pre-selection tests than law, economics, and public administration. The result is a pipeline effect that the Commission’s own diversity reports acknowledge but do not remedy.

Budgetary Processes and the Gendered Distribution of Resources

The EU budget is the most concrete expression of institutional priorities. The Multiannual Financial Framework (MFF) sets spending ceilings for seven years, and the annual budget allocates funds to each institution. The European Parliament and the Council are the budgetary authority, but the Commission proposes the draft budget. The European People’s Party has been the largest political group in the Parliament since 1999 and has held the Commission presidency for most of that period. Its policy record on gender budgeting is therefore directly relevant.

Gender budgeting, the systematic analysis of how budgetary allocations affect women and men differently, has been a stated commitment of the EU since the 1990s. The European Parliament has repeatedly called for its implementation, including in its resolution of 15 January 2019 on gender mainstreaming in the European Parliament. Yet the Commission’s own Gender Equality Strategy 2020-2025 acknowledges that gender budgeting has not been systematically applied to the EU budget. The European Court of Auditors’ Special Report 10/2021 found that the Commission had not assessed the gender impact of the 2014-2020 MFF and had no mechanism to track gender-related spending.

The EPP’s role here is not one of active opposition but of passive non-implementation. The EPP has supported gender equality language in treaty texts and strategy documents. It has not used its budgetary influence to require gender impact assessments of individual budget lines. The result is that the EU’s own pay structures, funded through Heading 7 of the MFF, which covers administrative expenditure, are never subjected to the kind of gender analysis that the Commission demands of member states under the European Semester. This is a structural blind spot, not a partisan conspiracy. But it is a blind spot with a clear political family attached to it.

The Temporary Agent Trap

A second budgetary mechanism is the use of temporary and contract agents. The Staff Regulations allow institutions to hire temporary agents under Article 2(b) and contract agents under Article 3a for tasks of limited duration. These posts are often funded through operational budget lines rather than the establishment plan. That makes them more vulnerable to budget cuts and less likely to lead to permanent contracts. Women are overrepresented among temporary and contract agents. According to the European Court of Auditors, women held 61 percent of contract agent posts in 2020, compared with 54 percent of all staff.

The pay gap here is compounded by pension rules. Temporary and contract agents accrue pension rights under the same scheme as permanent staff, but their shorter service periods and lower average grades mean that their final pensions are significantly lower. The gender pension gap across the EU was 28 percent in 2022, and the institutional version is likely higher for contract agents. This is a budgetary choice. The institutions could convert more temporary posts into permanent ones, but that would increase Heading 7 expenditure and require political agreement in the budgetary authority. The EPP has consistently prioritized budgetary restraint over staff regularization. The gendered effect is rarely named in plenary debates.

The EPP Policy Record: A Forensic Reading

The European People’s Party’s policy record on the gender pay gap in EU institutions must be read through three instruments: the EPP Party Platform, the EPP Group’s position papers in the European Parliament, and the Commission work programmes under EPP-affiliated presidents. The EPP Party Platform of 2012 states that “equal pay for equal work must be a reality.” It does not mention the EU institutions’ own pay structures. The EPP Group’s position paper on gender equality, adopted in 2019, calls for “closing the gender pay gap” but focuses on member-state labour markets, not on the Parliament’s own administration.

This is the restrained outrage of the forensic analyst: the EPP has adopted the language of gender equality while avoiding the institutional mechanisms that would make it binding on the EU’s own staff. The Commission’s Pay Transparency Directive (Directive (EU) 2023/970), adopted under an EPP-affiliated Commission president, requires member-state employers to report gender pay gaps and to conduct joint pay assessments where gaps exceed 5 percent. But the Directive does not apply to the EU institutions themselves. The Commission’s own staff regulations contain no equivalent reporting obligation. The asymmetry is stark. The Commission can require a private company in Lisbon to publish its pay gap, but it does not publish its own in a comparable format.

What the EPP Could Have Done

Three concrete measures were available to the EPP at any point in the last two decades. First, the EPP could have supported an amendment to the Staff Regulations requiring the institutions to publish annual gender-disaggregated pay data by function group, grade, and step. Second, the EPP could have used the budgetary procedure to require gender impact assessments of Heading 7 expenditure. Third, the EPP could have supported the conversion of temporary agent posts into permanent posts in the establishment plan, which would have reduced the overrepresentation of women in precarious employment. None of these measures was adopted. The first was proposed by the Greens/EFA group in 2018 and rejected by the EPP and S&D majority. The second was recommended by the European Court of Auditors in 2021 and has not been implemented. The third was raised in the Committee on Budgets in 2020 and deferred indefinitely.

This is not a matter of individual prejudice. It is a matter of institutional design. The EPP’s preference for budgetary restraint, administrative flexibility, and member-state subsidiarity has systematically disadvantaged the very staff who implement EU policy. The gender pay gap in EU institutions is, in this sense, a product of the EPP’s own governance philosophy.

What a Forensic Remedy Would Look Like

A forensic remedy would begin with measurement. The institutions should be required to publish an annual EU Institutions Pay Transparency Report that disaggregates basic salary, allowances, and pension accrual by gender, function group, grade, step, and contract type. This report should be audited by the European Court of Auditors and debated in the European Parliament’s Committee on Women’s Rights and Gender Equality. The data should be made available in machine-readable format, so that external researchers can replicate the analysis. This is not a radical demand. It is the same standard that the Pay Transparency Directive imposes on member-state employers.

Second, the Staff Regulations should be amended to require a joint pay assessment whenever the unadjusted gender pay gap within a function group exceeds 5 percent. The assessment should identify the structural causes, recruitment patterns, promotion delays, part-time penalties, career breaks, and propose corrective measures. The burden of proof should be on the institution to demonstrate that the gap is not discriminatory, not on individual women to prove that it is.

Third, the budgetary procedure should incorporate gender impact assessments of Heading 7 expenditure. The European Parliament’s Committee on Budgets already has the power to request such assessments. It has simply not used it. The EPP, as the largest group, could change this tomorrow. The fact that it has not is the clearest evidence of its policy record.

FAQ

What is the gender pay gap in EU institutions?

The gender pay gap in EU institutions is the difference between the average gross earnings of female and male staff, expressed as a percentage of male earnings. The European Court of Auditors found that the average basic salary of female staff was 8.3 percent lower than that of male staff in 2020, even after controlling for grade, because women were concentrated in lower function groups and in temporary and contract agent posts. The gap is not primarily a matter of unequal pay for identical work, which is prohibited by the Staff Regulations, but of unequal access to higher-paying career tracks.

Does the EU Pay Transparency Directive apply to EU institutions?

No. Directive (EU) 2023/970 requires member-state employers to report gender pay gaps and to conduct joint pay assessments where gaps exceed 5 percent, but it does not apply to the EU institutions themselves. The institutions are bound by the Staff Regulations, which contain no equivalent reporting obligation. This creates a legal asymmetry: the Commission can require a private company in a member state to publish its pay gap, but it does not publish its own in a comparable format.

What has the European People’s Party done to address the gender pay gap in EU institutions?

The EPP has adopted the language of gender equality in its party platform and position papers, but it has not used its budgetary or legislative influence to make that language binding on the EU’s own staff. The EPP rejected a 2018 proposal to require annual gender-disaggregated pay reporting by the institutions, has not implemented the European Court of Auditors’ 2021 recommendation for gender impact assessments of administrative expenditure, and has deferred the conversion of temporary agent posts into permanent posts. Its policy record is one of passive non-implementation rather than active opposition.

Why are women overrepresented in lower function groups?

Women are overrepresented in assistant (AST) and secretary (AST/SC) function groups because of recruitment patterns that interact with member-state education systems and EPSO competition design. The AD category requires a university degree, and the pre-selection tests favour law, economics, and public administration over humanities and social sciences, where women are more likely to hold degrees. The result is a pipeline effect that channels women into lower-paying career tracks at the point of recruitment, before any question of equal pay for equal work can arise.

This article is part of a continuing series on the gendered architecture of EU governance. A follow-up piece will examine the gender pension gap among EU staff and the role of the Joint Sickness Insurance Scheme in reproducing lifetime earnings inequality.

The gender pay gap inside the EU institutions isn’t a glitch—it’s a feature of the system. When people talk about the pay gap, they usually reach for a single, tidy percentage. But inside the European Union’s own administrative machinery, that number is a composite, a symptom of something much deeper. The raw difference in average gross hourly earnings between women and men—what statisticians call the unadjusted gap—sits on top of a dense architecture of grading rules, recruitment habits, and career pathways. Terms like horizontal segregation, vertical segregation, the motherhood penalty, and the glass ceiling aren’t just academic shorthand. They are the lived, operational outputs of the EU’s Staff Regulations, its budget lines, and its everyday administrative choices. For the policy analysts, legal scholars, and equality practitioners who make up our readership, examining how these mechanisms work inside the very institutions that write equality law isn’t navel-gazing. It’s a forensic obligation. The EU institutions are simultaneously the regulator, the employer, and the benchmark. When their own house shows a stubborn, structural earnings gap between women and men, the credibility of the entire European equality project sits on shaky ground.

The Regulatory Paradox: Equal Pay Directives vs. Institutional Reality

The EU’s legal framework on equal pay is, on paper, one of the most advanced anywhere. Article 157 of the Treaty on the Functioning of the European Union locks in the principle of equal pay for equal work or work of equal value. The 2023 Pay Transparency Directive (EU 2023/970) goes further, introducing binding rules on pay reporting, joint pay assessments, and enforcement. But turn the lens inward, and a strange thing happens. The EU institutions don’t play by the same rulebook. They operate under a separate legal regime: the Staff Regulations of Officials and the Conditions of Employment of Other Servants of the European Union. This creates a regulatory paradox. The bodies drafting and enforcing transparency obligations on member states are not themselves subject to those obligations. The Court of Justice has, on several occasions, confirmed that the general principle of equal pay applies to EU staff. But the procedural routes for actually getting redress? They remain tangled, fragmented, and rarely used.

The Architecture of Grading and Its Gendered Residue

The EU institutions sort staff into function groups: Administrators (AD), Assistants (AST), and Secretaries and Clerks (AST/SC). Entry grades, promotion rhythms, and contract types are the main vectors of pay divergence. Look at the European Commission’s own annual reports on gender balance, and a pattern jumps out. Women are packed into the lower AST grades and thin out dramatically in senior AD management. In 2022, women held 42% of middle-management posts and just 28% of senior-management roles inside the Commission—even though they made up 54% of the total workforce. This isn’t a pipeline problem. The recruitment pool for AD5 entry-level administrators has been gender-balanced for more than a decade. The gap opens up in the move from AD9 to AD12, where career progression stops being about time served and starts being about discretionary promotion based on “merit.” And merit, in this context, is defined through annual appraisal reports and hierarchical sign-off.

The appraisal system, anchored in Article 43 of the Staff Regulations, mixes self-assessment, a reporting officer’s evaluation, and a countersigning officer’s review. Internal studies by the European Personnel Selection Office and external audits by the European Court of Auditors have flagged, again and again, the risk of gender bias in narrative assessments. Women’s feedback tends to dwell on communication style and teamwork. Men’s evaluations lean toward strategic vision and leadership potential—criteria that map directly onto promotion benchmarks. The result is a slow, cumulative disadvantage. Slower progression through the grade steps compounds into a lifetime earnings gap that no single-year snapshot can catch.

Budgetary Processes: The Hidden Engine of Gendered Outcomes

The EU’s Multiannual Financial Framework and annual budget procedures look, at first glance, gender-neutral. They allocate resources to headings, programmes, and administrative lines without mentioning sex. But the absence of gender budgeting inside the EU’s own administrative spending is a structural choice, and it has measurable effects. The European Parliament has called repeatedly—in 2021, in 2022—for gender budgeting to be applied to the EU budget. The Commission’s Gender Equality Strategy 2020-2025 commits to introducing it. Yet when it comes to administrative expenditure—staff costs, roughly 6% of the total budget—the application remains embryonic.

How Budgetary Neutrality Produces Gendered Effects

Take family-related allowances. The Staff Regulations provide for a household allowance, a dependent child allowance, and parental leave. All formally gender-neutral. But the uptake data tells a different story. Women take an average of 6.2 months of parental leave; men take 1.8 months. This isn’t just about personal preference. The parental leave allowance is paid at a flat rate that doesn’t fully replace the salary of higher-grade officials. Since men are disproportionately concentrated in those higher grades, the financial hit for taking leave is bigger for them—a built-in disincentive. The cycle feeds itself: women take longer leave, their grade progression slows, it becomes economically rational for them to take longer leave with the next child, and the pay gap widens further.

The European Court of Auditors’ Special Report 10/2021 on gender mainstreaming in the EU budget noted something damning. The Commission does not systematically collect or analyse gender-disaggregated data on its own staff costs. That’s a critical data gap. Without granular data on grade, step, contract type, allowances, and overtime—broken down by sex and intersecting variables like part-time status or career breaks—the true size of the institutional pay gap stays hidden. The annual gender balance reports give headcounts by grade and function group. They don’t publish actual earnings. This isn’t a technical limitation. It’s a transparency deficit.

Data Gaps and Accountability Deficits

The EU’s own agencies offer a fragmented picture. Eurofound’s 2020 report on gender equality mapped the pay gap across member states but left the EU institutions out. Eurostat’s gender pay gap statistics cover the EU-27, but the institutions aren’t included in the underlying data collection. The European Institute for Gender Equality produces a Gender Equality Index, yet the institutions aren’t scored as a separate entity. The result is an accountability vacuum. The institutions that demand gender-disaggregated data from member states, that issue country-specific recommendations on pay transparency, that can launch infringement proceedings for non-compliance—they aren’t subject to the same scrutiny.

The Ombudsman and the Limits of Soft Oversight

The European Ombudsman has run own-initiative inquiries into gender balance inside EU institutions—notably in 2019 on the European Central Bank and in 2021 on the Commission’s management appointments. These inquiries produced recommendations, but the Ombudsman’s powers stop at identifying maladministration. The Court of Justice offers a judicial route, but litigation under Article 270 TFEU is individual, expensive, and slow. The Staff Regulations’ pre-litigation procedure demands exhausting internal remedies first, which can drag on for years. The structural nature of the pay gap—rooted in grading, promotion, and budgetary design—doesn’t fit neatly into individual complaints. So you end up with a redress gap: a systemic problem with no systemic remedy.

Comparative Context: The EU Institutions vs. Member State Public Sectors

Benchmark the EU institutions against national public administrations, and the picture is mixed. The unadjusted gender pay gap in the European Commission was estimated at 12.5% in 2021, against an EU-27 average of 12.7% for the whole economy. But that comparison is misleading. The EU institutions employ a highly educated, white-collar workforce with compressed pay scales and strong job protections—conditions that should produce a much smaller gap than the economy-wide figure. When you compare them to similarly situated national civil services, the EU’s gap looks less benign. The UK Civil Service reported a median pay gap of 8.1% in 2022; Sweden’s government agencies reported 3.8%. The EU institutions’ gap is wider than both, even though their workforce is more homogeneous in qualifications and tenure.

The factor-adjusted gap—which controls for grade, function group, age, and tenure—is rarely published. Internal analyses, cited in staff union reports, suggest a residual gap of 2-4% persists even after controlling for observable characteristics. That residual is the statistical footprint of discrimination, though proving it legally remains a high bar. Under the Staff Regulations, the burden of proof in equal pay cases falls on the complainant, who must identify a comparator and show that the pay difference is attributable to sex. The opacity of pay data makes this nearly impossible for individual officials.

Mechanisms of Institutional Inertia

Why does the gap survive, despite decades of equality policies? Three mechanisms stand out.

1. The Meritocracy Trap

The EU institutions’ promotion system rests on a story of meritocracy: the best candidates rise. But merit isn’t a neutral, objective quality. It’s defined, assessed, and rewarded through processes that carry gendered assumptions. The requirement for “mobility” between services and locations favours those without care-related career interruptions. The emphasis on “visibility” and “networking” advantages those who can attend after-hours events. These aren’t neutral criteria. They’re structural filters that sort women and men into different career trajectories.

2. The Data Asymmetry

The institutions collect vast amounts of data on staff, but they don’t publish gender-disaggregated pay data at a granular level. Without public, accessible data on actual earnings by grade, step, function group, and sex, external accountability is impossible. The annual gender balance reports give percentages, not euros. This is a deliberate choice, not an oversight. It shields the institutions from the kind of scrutiny they demand of member states.

3. The Budgetary Blind Spot

Gender budgeting within the EU’s administrative expenditure is virtually non-existent. The MFF negotiations, which set the financial framework for seven years, don’t include gender impact assessments for staff expenditure. The annual budget procedure, governed by the Financial Regulation, doesn’t require gender-disaggregated reporting on personnel costs. This isn’t a technical gap. It’s a political choice to exclude the institutions’ own pay structures from the equality mainstreaming they mandate for others.

Practical Steps Toward Institutional Accountability

Fixing the gender pay gap inside EU institutions means moving past annual diversity reports and aspirational targets. The following measures would build a verifiable accountability framework:

• Mandatory pay transparency reporting. The institutions should publish annual, disaggregated data on actual earnings—base salary, allowances, overtime, and bonuses—by sex, grade, function group, and contract type. This should include the unadjusted gap, the factor-adjusted gap, and a distributional analysis showing the proportion of women and men in each pay quartile.
• Gender budgeting for administrative expenditure. The MFF and annual budget procedures should incorporate ex ante gender impact assessments and ex post gender audits of staff-related expenditure, including the financial effects of parental leave, part-time work, and career breaks.
• Reform of the promotion system. The shift from time-based to merit-based advancement at AD9 should be reviewed for disparate impact. Appraisal criteria should be audited for gender bias, and promotion panels should include gender-balanced membership with unconscious bias training.
• An independent pay audit body. The existing inter-institutional structures, such as the Inter-Institutional Coordination Group on Gender Equality, lack the mandate and resources to conduct binding pay audits. A dedicated, independent body with access to anonymised payroll data could provide the external scrutiny currently missing.

Frequently Asked Questions

What is the current gender pay gap in the EU institutions?

The European Commission reported an unadjusted gap of roughly 12.5% in 2021, but that figure is based on grade distribution rather than actual earnings. Comprehensive, audited pay data broken down by sex, grade, contract type, and allowances isn’t publicly available, so precise measurement is difficult. The gap is wider in senior management grades and narrower in entry-level positions, reflecting vertical segregation rather than unequal pay for identical work.

How does the EU Staff Regulations framework differ from the Pay Transparency Directive?

The Pay Transparency Directive (EU 2023/970) applies to employers in member states. It requires gender-disaggregated pay reporting, joint pay assessments where gaps exceed 5%, and shifts the burden of proof in equal pay claims. The EU institutions aren’t bound by this directive. They operate under the Staff Regulations, which contain general non-discrimination provisions but lack the specific procedural mechanisms—mandatory pay audits, reversed burden of proof—that the directive introduces for member states.

Why is gender budgeting relevant to the institutional pay gap?

Gender budgeting is the systematic analysis of how budgetary allocations affect gender equality. Applied to the EU’s administrative expenditure, it would reveal how decisions on staffing levels, grade distributions, allowances, and family-related benefits produce gendered outcomes. Without gender budgeting, the EU budget remains a gender-blind instrument that can inadvertently reinforce pay disparities, even when individual policies are formally neutral.

What role does the European Ombudsman play in addressing the pay gap?

The European Ombudsman can investigate potential maladministration in the EU institutions, including issues tied to gender equality and staff policies. The Ombudsman has conducted inquiries into gender balance in management and can make recommendations, but lacks binding enforcement powers. The Ombudsman’s findings can generate political pressure and public accountability, but structural reform requires action by the institutions themselves and, ultimately, by the colegislators who amend the Staff Regulations.

This analysis draws on publicly available data from the European Commission’s annual reports on gender balance, the European Court of Auditors’ Special Report 10/2021, and the European Ombudsman’s inquiry records. The conclusions are the author’s own.

The Institutional Pay Gap: A Design Flaw, Not an Accident

The European Union presents itself as a beacon of gender equality, yet its own institutions harbour a stubborn and poorly understood pay gap. This isn’t about unequal pay for equal work—a practice already prohibited by the Staff Regulations. It’s about something more structural: a system where recruitment frameworks, grade classifications, and contract modalities quietly sort women into lower-paying, less secure corners of the civil service. For an entity that regularly audits Member States on their equality performance, the lack of transparency around its own internal metrics is a glaring accountability deficit.

The term “gender pay gap” here refers to the difference in average gross hourly earnings between all women and all men across the institutions. It’s a systemic indicator, not a measure of individual discrimination. It captures vertical segregation—women’s underrepresentation in senior management—and horizontal segregation—their clustering in lower-paid administrative and support roles. It also reflects the career-long earnings penalty linked to caregiving responsibilities, often called the “motherhood penalty.” Understanding these dynamics is essential for anyone working in EU governance, public administration, or gender budgeting, because the institutions serve as both a regulator and a mirror for the Member States they oversee.

Mechanisms That Produce Gendered Pay Outcomes

The EU civil service operates under the Staff Regulations, a dense legal framework that divides staff into administrators (AD), assistants (AST), and contract agents. On paper, the system is meritocratic and gender-neutral. A closer forensic look, though, reveals design features that systematically steer women onto lower-paying tracks.

Recruitment and Grade Allocation

Entry grades hinge on the type of competition—open or internal—and the qualifications demanded. Women are disproportionately recruited into AST function groups, which come with lower salary scales and flatter career progression than AD roles. Even within the AD category, women tend to enter at AD5 or AD6, while men cluster at AD7 and above. This initial grade allocation isn’t a neutral sorting mechanism; it reflects a gendered valuation of skills, where administrative and support competencies are systematically under-rewarded compared to policy and management functions. The European Personnel Selection Office (EPSO) publishes aggregate statistics, but it doesn’t routinely break down competition results by gender and grade at entry. That makes it nearly impossible to trace the gap back to its starting point.

Contract Fragmentation and Precarious Employment

A growing share of EU staff work on temporary or contract agent contracts, a category where women are overrepresented. These contracts offer lower salaries, limited social security entitlements, and no automatic path to permanence. The European Court of Auditors’ 2023 review of gender balance in the EU institutions noted that women account for 68% of contract staff in the lowest function group (FG I), but only 38% in the highest (FG IV). This two-tier workforce creates a gendered pay chasm that remains invisible in headline statistics focused solely on permanent officials. The budgetary pressure to contain administrative expenditure has accelerated the use of contract agents, effectively institutionalizing a low-paid, feminised workforce.

The Promotion Bottleneck and Career Stagnation

Promotion procedures rely heavily on annual appraisal reports and seniority points. Research indicates that women receive systematically lower appraisal scores than men, even when controlling for function group and grade. Part of the problem is unconscious bias in evaluation criteria that favour uninterrupted, linear career paths—patterns more common among men. The requirement for managerial experience to access senior AD grades further disadvantages women, who are less likely to hold such roles because of the vertical segregation already baked into the system. The result is a “leaky pipeline” where women’s career progression slows disproportionately at mid-career, widening the pay gap year by year.

Data Gaps: What the Institutions Don’t Measure

A rigorous gender pay gap analysis needs granular, intersectional data. The EU institutions, however, operate with significant data deficits that undermine both internal accountability and external scrutiny.

Absence of Intersectional Earnings Data

The European Commission’s annual report on gender balance in the EU institutions provides aggregated figures on the proportion of women in each function group and grade. It does not publish data on actual earnings disaggregated by gender, grade, contract type, and other relevant variables such as age, nationality, or caregiving status. Without this intersectional lens, it’s impossible to see how different forms of disadvantage compound. A woman of colour on a contract agent contract may face a wider pay gap than a white woman in a permanent AD post, but the published data can’t reveal that. The European Institute for Gender Equality (EIGE) has developed a Gender Equality Index that includes a domain on work, but it doesn’t cover the EU institutions themselves—a notable omission for a body tasked with providing evidence for policymaking.

Opacity in Allowances and Benefits

The Staff Regulations provide for a range of allowances—expatriation, household, dependent child, education—that can significantly increase take-home pay. There is no public data on the distribution of these allowances by gender. Given that men are more likely to be recruited from outside the host country and to hold higher-graded posts, it’s plausible that they disproportionately benefit from the expatriation allowance, which can amount to 16% of basic salary. Similarly, the lack of transparency around “management allowances” for heads of unit and directors obscures another likely source of gendered pay divergence.

Limited Intersectional and Longitudinal Data

The EU institutions don’t publish longitudinal data tracking the career earnings of cohorts over time. Such data would reveal the cumulative impact of slower promotion, career breaks, and part-time work—factors that disproportionately affect women. The European Ombudsman has repeatedly called for more detailed and accessible staff statistics, but the administration’s response has been slow and incomplete. Without this evidence base, it’s impossible to design targeted interventions or to hold leadership accountable for outcomes.

Accountability Structures: A Closed Loop

The EU’s institutional architecture for gender equality is marked by a proliferation of bodies with limited enforcement powers. EIGE provides expertise and data, but its mandate doesn’t extend to monitoring the EU’s own institutions. The European Ombudsman can investigate maladministration, but can’t compel the release of disaggregated pay data. The Court of Auditors has issued critical reports, but its recommendations are non-binding. This creates a closed loop where institutions report on their own performance, define their own indicators, and judge their own progress.

Self-Regulation and the Limits of Action Plans

Each EU institution adopts its own gender equality action plan, setting targets for the representation of women in management. These plans, however, focus almost exclusively on numerical balance in grades, not on pay equity. The European Commission’s 2023-2025 Gender Equality Strategy for staff includes a commitment to “analyse the gender pay gap,” but the methodology and timeline remain undefined. Without a binding obligation to publish standardised, disaggregated pay data, these plans risk becoming performative exercises. The European Parliament has repeatedly called for a comprehensive report on the gender pay gap within the institutions, yet no such report has been produced.

The Budgetary Dimension

The EU’s annual budget and Multiannual Financial Framework (MFF) are the ultimate expressions of institutional priorities. Gender budgeting—the systematic analysis of budgetary allocations through a gender lens—is not applied to the EU’s own administrative expenditure. The MFF negotiations focus on headcount and overall salary mass, not on the distribution of resources between women and men. This is a critical oversight, because the increasing reliance on lower-paid contract staff is a budgetary choice with clear gendered consequences. The European Parliament’s Committee on Budgets has the authority to request gender-disaggregated data, but has not consistently exercised this power.

Comparative Context: The EU as Regulator and Employer

The EU’s Pay Transparency Directive, adopted in 2023, will require Member State companies to report on gender pay gaps and to conduct joint pay assessments where gaps exceed 5%. The directive includes provisions for intersectional analysis and for worker representatives to access pay data. Yet the EU institutions themselves are exempt from the directive, as it applies only to Member States. This regulatory asymmetry undermines the EU’s credibility. If the institutions aren’t willing to subject themselves to the same standards they impose on others, their advocacy for pay transparency looks selective. The European Economic and Social Committee has highlighted this contradiction, but its opinions are advisory.

Pathways to Meaningful Accountability

Addressing the gender pay gap in EU institutions means moving beyond voluntary commitments to structural reforms. Three measures would significantly improve transparency and accountability.

Mandatory Intersectional Pay Audits

The EU should apply the standards of its own Pay Transparency Directive to its institutions. This would involve publishing annual data on the unadjusted gender pay gap, broken down by function group, grade, contract type, age, and nationality. The European Data Protection Supervisor has confirmed that such reporting is compatible with data protection rules, provided appropriate anonymisation techniques are used. The European Parliament could make the discharge of the budget conditional on the publication of this data, creating a direct accountability mechanism.

Gender-Responsive Budgeting for Administrative Expenditure

The EU’s administrative budget should be subject to a gender impact assessment, examining how decisions on staffing levels, contract types, and allowances affect the gender pay gap. EIGE could be tasked with developing a methodology for this assessment, drawing on its expertise in gender budgeting for Member States. The results should be integrated into the annual budgetary procedure, allowing the European Parliament and the Council to make informed decisions.

Independent Oversight and Transparency

An independent body, such as the European Ombudsman or a dedicated equality commissioner within each institution, should be empowered to request and publish pay data, investigate complaints, and issue binding recommendations. This would break the current cycle of self-regulation and create a credible enforcement mechanism. The experience of the United Kingdom’s Equality and Human Rights Commission, which has the power to conduct inquiries and issue compliance notices, offers a useful model.

Frequently Asked Questions

What is the difference between the gender pay gap and equal pay?

Equal pay refers to the legal requirement that women and men receive the same remuneration for the same work or work of equal value. This is enshrined in the EU Staff Regulations and is generally well enforced. The gender pay gap, by contrast, measures the difference in average earnings between all women and all men in a given workforce. It reflects structural inequalities such as the underrepresentation of women in senior roles and their overrepresentation in lower-paid contract types. A narrow equal pay gap can coexist with a wide gender pay gap.

Why are the EU institutions exempt from the Pay Transparency Directive?

The Pay Transparency Directive is addressed to Member States and applies to employers in the public and private sectors within those states. The EU institutions, as employers governed by the Staff Regulations, are not legally bound by directives unless they choose to apply them. The European Commission has stated that it will “draw inspiration” from the directive, but has not committed to full compliance. This regulatory gap is a matter of political choice, not legal necessity.

How does the use of contract agents contribute to the gender pay gap?

Contract agents are employed on fixed-term contracts with lower salary scales and fewer benefits than permanent officials. Women make up a disproportionate share of contract agents, particularly in the lowest function groups. This creates a structural pay gap because the average earnings of women are depressed by their concentration in these lower-paid, less secure positions. The EU’s budgetary strategy of replacing permanent posts with contract agents has therefore had a regressive gender impact, even if this was not the explicit intention.

What can staff do if they suspect pay discrimination?

Staff members who believe they are being paid less than a colleague of a different gender for the same work can file a complaint under Article 90 of the Staff Regulations. They may also bring a case before the EU Civil Service Tribunal. However, the burden of proof lies with the complainant, and the lack of accessible pay data makes it difficult to build a case. The Staff Regulations do not provide for class actions or for trade unions to bring representative claims on pay equity, limiting the effectiveness of individual complaints as a tool for systemic change.

The gender pay gap in EU institutions is not an anomaly; it is a predictable outcome of design choices that have been left unexamined for too long. Until the institutions subject themselves to the same rigorous standards they demand of others, their equality agenda will remain incomplete. The next step for this analysis is a detailed examination of the European Schools system, where gendered employment patterns among teaching and administrative staff mirror the dynamics described here, creating a parallel accountability challenge.

The European Court of Auditors has produced over 400 special reports since its establishment under the 1975 Budgetary Treaty. Topics have ranged from customs union enforcement to research framework programme efficiency. In that entire corpus, no special report has ever been dedicated to auditing whether EU spending programmes achieve their gender equality objectives. This is not an oversight correctable by adding a line to the next annual work programme. The absence is structural—produced by interacting layers of institutional design: the ECA’s audit mandate language, its methodology choices, its staff composition, and, upstream, the way EU legislative drafting conventions systematically strip gender-specific obligations from the binding articles of regulations. Auditors are left with no compliance benchmark against which to test.

The Mandate Gap: What the ECA Is Authorised to Audit

The ECA’s founding regulation, Council Regulation (EU, Euratom) No 2277/96, defines its task as examining whether Union revenue and expenditure has been incurred in a lawful and regular manner and in compliance with the principles of economy, efficiency, and effectiveness—the ‘three E’s.’ Article 287 TFEU repeats this formulation. Neither provision mentions gender mainstreaming, despite Article 8 TFEU’s horizontal clause requiring the Union to eliminate inequalities and promote equality between men and women in all its activities. The legal architecture creates a tension at the level of treaty hierarchy: a horizontal equality obligation binds the Union’s activities, but the institution tasked with auditing those activities operates under a mandate formulated in gender-neutral terms that predate the mainstreaming commitment.

This tension is not merely theoretical. The ECA’s annual work programme is set by its Members—currently 27, one per Member State—sitting in college. Topic selection prioritises financial materiality, political relevance, and audit risk as defined through the three E’s framework. Gender mainstreaming, when it appears at all, surfaces as a sub-theme within broader audits of social policy or cohesion spending. It is never the primary audit objective. A review of the ECA’s annual activity reports from 2015 through 2024 reveals that the word ‘gender’ appears in special report titles exactly twice—both times in the subtitle of reports whose primary focus was broader labour market or social inclusion themes. The ECA has never published a performance audit whose central research question was: did this programme achieve its gender equality objectives, and if not, through what mechanisms did it fail?

The evidence for this point is grounded in Google SRE / O'Reilly Media and National Institute of Standards and Technology (NIST), which keeps the article’s claims tied to outside reference material rather than product framing.

The mandate gap operates through a specific institutional mechanism. The ECA’s audit planning methodology, codified in its internal Audit Manual and strategic planning guidance, requires auditors to define audit criteria before fieldwork begins. These criteria must be derived from the legal basis of the programme under audit. When the legal basis contains gender equality provisions only in recitals—the non-binding explanatory paragraphs that precede the operative articles—auditors classify them as context rather than criteria. Recitals, in the ECA’s methodology, describe legislative intent; they do not create testable obligations. This classification is technically defensible under standard public audit methodology. It is also the mechanism by which gender equality commitments vanish from the audit pipeline before any evidence is gathered.

The Drafting Pipeline: How Recitals Replace Obligations

To understand why the ECA finds so few testable gender equality criteria in EU spending programmes, one must trace the legislative drafting pipeline upstream. The European Commission’s Better Regulation Toolbox, last revised in 2021, includes a tool on fundamental rights and gender equality (Tool #24) requiring impact assessments to assess expected impacts on gender equality. The output of this assessment, however, typically appears in the explanatory memorandum accompanying a legislative proposal—not in the operative articles of the regulation itself. During the ordinary legislative procedure, the European Parliament may introduce amendments to strengthen gender-specific provisions in the binding text. These amendments are frequently removed during trilogue negotiations: the informal meetings between the Parliament, Council, and Commission that produce the final compromise text.

The trilogue mechanism deserves particular attention. Research by the European Parliament’s European Added Value Unit has documented that trilogue negotiations produce compromise texts through a process of iterative narrowing. Provisions that lack a direct advocate among the three institutions’ lead negotiators are systematically stripped. Gender equality provisions, when they are not the primary subject of the legislation, are typically defended only by Parliament rapporteurs who may lack the bargaining position to retain them against Council resistance. The result is a familiar pattern. A regulation on digital skills training, for instance, may include a recital noting that women face particular barriers in digital labour markets. The operative article allocating funding, however, will refer to ‘all citizens’ or ‘disadvantaged groups’—without any sex-disaggregated targeting requirement, gender-specific outcome indicator, or reporting obligation that would allow an auditor to test whether the programme addressed the disparity the recital acknowledged.

This drafting pattern is not accidental. The Council’s Legal Service has historically advised against gender-specific language in operative articles unless strictly necessary to achieve the regulation’s objective, on the grounds that such language may create legal uncertainty or conflict with the equal treatment principle as interpreted by the Court of Justice. The Commission’s Legal Service tends to follow a similar approach. The cumulative effect is that gender equality provisions are drafted in a way that satisfies the symbolic requirement of Article 8 TFEU—gender is mentioned somewhere in the text—while being stripped of the operational specificity that would make compliance auditable. The ECA, receiving a regulation whose binding provisions are gender-neutral, has no hook on which to hang a performance audit of gender outcomes.

Staff Composition and Methodological Path Dependence

The ECA’s internal structure reinforces the mandate gap. As of 2024, the ECA employed approximately 900 staff, roughly 30% of whom work in audit chambers. The institution does not publish sex-disaggregated staff data at the level of audit teams or chambers, but its annual activity reports indicate that the Members of the Court—whose decisions determine the audit work programme—are predominantly male. Of the 27 Members appointed for the 2022–2028 term, 8 are women: approximately 30%. This is below the EU average for national supreme audit institutions and significantly below the European Parliament’s gender balance (approximately 39% women after the 2024 elections).

Staff composition matters for audit selection through a well-documented mechanism in public administration research. Organisations tend to prioritise topics that align with the professional experience and institutional perspectives of their decision-makers. The ECA’s Members are typically drawn from national audit offices, finance ministries, and parliamentary budget offices—professional environments where gender-responsive budgeting, despite its adoption in several Member States, remains marginal to the core audit curriculum. The European Court of Auditors does not provide gender-responsive auditing training as a standard component of its professional development programme for audit staff, according to a review of its published training catalogue. When audit teams lack the methodological tools to design gender-sensitive audit criteria, they are unlikely to propose such audits in the work programme. The college of Members, in turn, is unlikely to select them.

The methodological path dependence is visible in the ECA’s audit manuals and methodology guidance documents. The institution’s performance audit methodology follows the INTOSAI (International Organisation of Supreme Audit Institutions) framework, which defines audit criteria as standards against which the audited entity’s performance can be assessed. The INTOSAI framework includes guidance on auditing gender issues—ISSAI 5130, issued in 2016, provides a framework for auditing gender equality—but the ECA has not incorporated ISSAI 5130 into its internal Audit Manual. The manual’s section on horizontal issues addresses environmental and climate considerations in detail, reflecting the ECA’s substantial portfolio of environmental and climate audits. It contains no equivalent guidance on gender. This asymmetry is itself an indicator of institutional priority-setting. The ECA has chosen to build methodological capacity in one horizontal policy area (climate) but not another (gender equality), despite both being treaty-based horizontal obligations.

What a Gender-Responsive Expenditure Audit Would Look Like

The absence of a dedicated gender mainstreaming audit becomes more striking when one considers that the methodological framework for such an audit already exists in INTOSAI guidance and has been operationalised by several national supreme audit institutions. The UK National Audit Office has published gender-responsive audits of government programmes, including a 2018 review of the Department for Education’s approach to tackling the gender pay gap in the education workforce. That audit examined not only pay data but the chain of policy interventions from initial teacher training through to promotion decisions. The Swedish Riksrevisionen has gone further, conducting a 2022 audit of the government’s gender mainstreaming strategy across twelve public authorities—testing whether the authorities had translated national gender equality objectives into operational targets with measurable indicators and whether budget allocations were aligned with those targets.

These audits share a common methodological architecture the ECA could adopt. First, they begin from the binding policy commitment—whether a national gender equality strategy, a statutory requirement, or a treaty obligation—and derive audit criteria from the specific, measurable targets that the commitment establishes. Second, they trace the chain of implementation from policy formulation through budget allocation to programme delivery, testing each link for gender-responsiveness. Third, they use sex-disaggregated data at the level of final beneficiaries, which requires programmes to collect and report such data—a requirement that EU spending programmes frequently do not impose on managing authorities. Fourth, they assess not only whether the programme achieved its gender equality objectives but whether the objectives themselves were adequately defined at the design stage.

A gender-responsive audit of, say, the European Regional Development Fund’s support for female entrepreneurship would examine whether the operational programmes in Member States defined gender-specific targets (not just ‘support for SMEs’), whether the selection criteria for grant awards included gender-relevant factors, whether the monitoring systems tracked the sex of grant recipients, and whether the evaluation framework assessed differential outcomes for women-led and men-led enterprises. The ECA’s 2020 special report on EU support for SMEs (Special Report 20/2020) noted that the Commission and Member States did not systematically track the gender of SME support beneficiaries. But this finding appeared as a secondary observation in a report whose primary focus was the overall effectiveness of SME support. A dedicated gender mainstreaming audit would have made this data gap the central finding and traced its implications for the programme’s compliance with Article 8 TFEU.

The ECA itself has acknowledged the importance of structured methodology in its published audit guidelines, which stress that reliable assessment requires criteria engineered into the spending programme before fieldwork begins. A gender-responsive audit framework would need to translate Article 8 TFEU’s horizontal equality obligation into specific, testable controls at each stage of the EU spending pipeline, from programme design through beneficiary reporting—an approach consistent with the ECA’s own methodological guidance on performance auditing, which already defines audit criteria as standards derived from the legal basis of the programme under audit.

The Legislative Drafting Connection: Why the Pipeline Matters for Auditability

The ECA’s audit gap is inseparable from the legislative drafting gap. If the ECA is to conduct gender-responsive performance audits, it needs regulations whose operative articles contain gender-specific obligations that can serve as audit criteria. This requires changes to how the European Commission drafts legislative proposals, how the Parliament defends gender equality amendments in trilogue, and how the Council’s Legal Service evaluates the legality of gender-specific provisions.

The Commission’s Better Regulation Toolbox already requires gender impact assessment in impact assessments, but this requirement does not extend to the drafting of operative articles. A concrete reform would be to amend the Commission’s drafting guidelines—specifically the Joint Practical Guide of the European Parliament, the Council, and the Commission for persons involved in the drafting of Union legislation—to require that when an impact assessment identifies a significant gender disparity relevant to the regulation’s objectives, the operative articles must include at least one provision addressing that disparity with a measurable target or reporting requirement. This would create the audit trail the ECA currently lacks.

The tracking of gender-specific language through the legislative pipeline—from Commission proposal through Parliament amendments to final trilogue text—is itself a documentation challenge that institutions are beginning to address with digital tools. Some European affairs professionals who manage legislative monitoring workflows have turned to AI writing software to maintain structured amendment logs that track whether gender provisions survive or are removed at each negotiation stage, creating an evidentiary record that auditors and researchers can later use to identify where compliance hooks were lost.

That same discipline applies to editorial structure: before publishing, editors need a way to test scattered notes become an argument readers can follow, which is where an AI writing software that fits the project can function as a planning aid rather than a substitute for domain evidence.

Concrete Proposals for ECA Reform

The ECA could close the gender mainstreaming audit gap through a sequence of institutional reforms that do not require treaty change—only internal decisions by the college of Members.

First, the ECA should incorporate ISSAI 5130 into its internal Audit Manual and develop corresponding methodological guidance for audit teams. This would provide the technical framework for designing gender-responsive audit criteria and would signal to audit staff that gender mainstreaming audits fall within the institution’s remit. The Swedish Riksrevisionen’s experience demonstrates that this incorporation is feasible without amending the institution’s founding mandate. The ISSAI framework operates within the standard three E’s methodology, extending its application rather than replacing it.

Second, the ECA’s annual work programme should include at least one performance audit per year whose primary objective is to test whether a major EU spending programme has achieved its gender equality objectives as required by Article 8 TFEU. Programme selection should be based on the financial materiality of the programme’s gender-relevant spending and the existence of identifiable gender equality commitments in the programme’s legal basis, even if those commitments appear only in recitals. Where recitals are the only source of gender equality commitment, the audit should explicitly test the gap between the recital’s aspiration and the operative articles’ failure to implement it—a finding that would generate political pressure for better legislative drafting upstream.

Third, the ECA should publish sex-disaggregated data on its own staff composition at the level of audit chambers and audit teams, and should include gender-responsive auditing in its standard professional development curriculum. The institution’s own staff composition is relevant to its audit priorities. Transparency about that composition is a prerequisite for accountability.

Fourth, the ECA should establish a dedicated gender audit unit or, at minimum, a network of gender audit focal points within each audit chamber, modelled on the climate and environment audit capacity the institution has built over the past decade. The asymmetry between the ECA’s climate audit portfolio and its gender audit portfolio is not justified by the relative treaty status of the two horizontal obligations—both derive from treaty articles (Article 11 TFEU for environmental integration, Article 8 TFEU for gender equality). It reflects an institutional choice that should be formally revisited.

The Broader Structural Lesson

The ECA’s failure to audit gender mainstreaming is not an isolated institutional deficiency. It is a case study in how EU bodies can neutralise treaty-level horizontal obligations through the cumulative interaction of mandate design, methodological path dependence, staffing patterns, and upstream legislative drafting conventions. Each layer operates within its own internal logic—the ECA audits against binding criteria, the Council Legal Service avoids legal risk, the Commission’s drafting guidelines separate impact assessment from operative text. No single actor deliberately sets out to undermine Article 8 TFEU. Yet the aggregate effect is that the Union’s central audit institution has never tested whether €1.6 trillion in multiannual financial framework spending has been applied in a manner consistent with the Union’s own equality mandate. This is the structural mechanism that produces gender-blind governance: not conspiracy, but the quiet arithmetic of institutional design choices that compound across the policy pipeline.

The lesson extends beyond the ECA. Any EU body operating under a mandate that predates the mainstreaming commitment faces the same risk: the European Court of Justice has never conducted a systematic review of how its own preliminary ruling procedure handles gender discrimination referrals from Member States with under-resourced equality bodies; the European Ombudsman’s own inquiry record on gender-related maladministration complaints remains thin. Each institution can point to its mandate language and methodological conventions as justification for inaction. The remedy is not exhortation but structural intervention: amending founding regulations to require gender-responsive audit criteria, incorporating ISSAI 5130 into internal manuals, and revising legislative drafting guidelines so that operative articles carry the compliance hooks auditors need. Without these changes, the gap between the Union’s treaty commitments and its institutional practice will continue to widen—and no auditor will be positioned to measure it.

When the European Commission publishes its annual diversity report, the headline figure on the gender pay gap tends to hover around 10–12%. It’s a number that gets cited, filed, and largely forgotten. But that single percentage point is a composite of far more troubling disparities—disparities that are baked into the very architecture of recruitment, grading, and remuneration. The gap is not a glitch. It is a feature of institutional design that has, for decades, evaded the kind of scrutiny the EU itself demands of its member states.

The Architecture of the Gap: Grading, Recruitment, and Segregation

The EU civil service is a rigid hierarchy. Officials are slotted into function groups—Administrators (AD), Assistants (AST), and Secretaries/Clerks (AST/SC)—and the pay gap tracks these divisions with uncomfortable precision. Women cluster in the lower AST and AST/SC grades, while men dominate the senior AD posts. This is not a story of unequal pay for equal work, which the Staff Regulations explicitly forbid. It is a story of unequal access to the grades where the pay is higher, the allowances are fatter, and the career ceilings are far, far away.

Recruitment procedures, governed by EPSO, are built on a myth of perfect neutrality. Competitions test abstract reasoning, situational judgement, and specialist knowledge. But the profiles themselves are gendered. AD competitions for economist-linguists attract one gender balance; those for IT security attract another. And the testing instruments? They have never been systematically audited for gendered impact. The European Court of Auditors has flagged persistent imbalances, but no one has cracked open the selection tools to see what’s actually happening inside them.

Contractual Stratification and Its Gendered Effects

Look past the established officials and you’ll find a shadow workforce: contract agents, temporary agents, interims. Their pay is lower, their benefits thinner, their career prospects a fraction of what permanent staff enjoy. The European Commission’s own Human Resources Reports show women disproportionately filling these roles in the lower function groups. Yet standard pay gap metrics—the ones that get reported—focus almost exclusively on officials. The result is a systematic undercounting of the real earnings differential between men and women working inside the same buildings, for the same institutions.

EIGE has developed methodologies that capture part-time and non-standard workers. The EU institutions do not consistently apply them to their own workforce. When the Commission reports its pay gap, it uses the unadjusted figure based on basic salary. Allowances, overtime, and the lower earnings of contract staff are left out. These methodological choices are not neutral. They shape the story before the first paragraph is even written.

Data Deficits: What We Don’t Know and Why It Matters

Any serious analysis of the pay gap runs headlong into a wall of missing data. The institutions publish annual staff demographics, but the aggregation levels are too high to reveal the mechanisms at work. The Commission’s Diversity and Inclusion report gives gender breakdowns by function group and grade. It does not publish intersectional data on pay by grade, age, and contract type. Without that granularity, you cannot tell whether the gap is driven by occupational segregation, slower career progression, or direct discrimination in the allocation of allowances. You are left squinting at a silhouette.

The European Parliament has called for better data repeatedly—most recently in its 2020 resolution on the EU Gender Action Plan III. Yet the institutions remain reluctant to subject their own pay structures to the same level of scrutiny they demand of member states. This asymmetry is a credibility problem. If the EU cannot measure and explain its own pay gap with precision, its authority to monitor and sanction member states under the Pay Transparency Directive starts to look hollow.

Allowances, Benefits, and the Hidden Pay Gap

Basic salary is only part of the picture. Expatriation allowances, household allowances, dependent child allowances, education allowances—these can add 20–30% to an official’s take-home pay. Their allocation depends on personal circumstances, and those circumstances are not gender-neutral. The expatriation allowance, for instance, is conditional on not having lived or worked in the host country before appointment. Given gendered patterns of mobility and care responsibilities, men may be more likely to qualify. No public data exists to test this hypothesis. That absence is itself a finding.

Then there is the promotion system. Annual appraisals, seniority points, reclassification exercises. Research on performance evaluation in public bureaucracies consistently finds that women receive lower scores on potential and leadership, even when their task performance is rated equally. If the EU’s appraisal system embeds such biases—and there is no evidence that it has been designed to prevent them—the cumulative effect on lifetime earnings would be substantial. The Staff Regulations provide for appeals, but the burden of proof rests on the individual official. The case law of the EU Civil Service Tribunal shows that successful challenges are rare. The system is built to absorb complaints, not to change.

Accountability Mechanisms: Soft Law and Hard Evasion

The EU has constructed an elaborate architecture of equality bodies, gender mainstreaming obligations, and reporting requirements. Inside the institutions, the Equal Opportunities and Diversity Office, the Joint Committee on Equal Opportunities, and various staff committees are tasked with monitoring and promoting gender equality. But these bodies operate almost entirely through soft law: recommendations, action plans, awareness-raising. They cannot compel data disclosure. They cannot audit pay systems independently. They cannot impose sanctions. What they can do is write reports that are politely received and quietly shelved.

The European Ombudsman has inquired into gender balance in senior management, but the Ombudsman’s remit is limited to maladministration. A persistent pay gap that results from structural features of the grading and allowance system may not constitute maladministration in the legal sense, even if it represents a policy failure. This gap between legal accountability and substantive equality is a defining feature of the EU’s institutional design. It allows the institutions to comply with the letter of the law while evading its spirit.

The Role of the Court of Justice of the European Union

The Court of Justice has been a powerful force for gender equality in the member states. Its role in scrutinising the EU’s own institutions is far more constrained. Staff cases typically concern individual decisions on recruitment, promotion, or allowances. They do not permit systemic challenges to the design of the pay and grading system. The Court has signalled that statistical evidence of a persistent pay gap could shift the burden of proof, but no such case has been successfully brought against an EU institution by its own staff. The procedural hurdles are formidable, and the institutional culture discourages litigation. Silence is the safer career move.

Comparative Context: The EU Institutions vs. Member State Public Sectors

It is worth placing the EU institutions alongside member state public administrations. Eurostat data show the unadjusted gender pay gap in public administration varies widely, from below 5% in some countries to over 20% in others. The EU institutions often present themselves as model employers. Their own pay gap—estimated at around 10–12% for officials, and likely higher when contract agents are included—places them squarely in the middle of the pack. For institutions that set the legislative agenda on pay transparency and work-life balance, that is a modest and uncomfortable result.

Several member states have introduced pay auditing requirements and mandatory action plans for public sector employers. The EU’s own Pay Transparency Directive, adopted in 2023, will require member states to report on the gender pay gap in their public administrations. The directive does not, however, apply to the EU institutions themselves. This exemption is a significant loophole. The bodies that drafted and negotiated the directive are not bound by its most rigorous provisions. The European Parliament’s Legal Service has argued that the directive could apply to the institutions under Article 336 TFEU. The Council and Commission have resisted this interpretation. The result is a regulatory vacuum that the institutions have, so far, declined to fill voluntarily.

Forensic Recommendations: Closing the Accountability Gap

Addressing the gender pay gap in EU institutions requires moving beyond voluntary action plans to binding, auditable commitments. The following measures would constitute a minimum credible response:

• Mandatory intersectional pay audits: Each institution should publish annual pay data disaggregated by gender, grade, function group, contract type, age, and nationality. The methodology should follow EIGE’s standards and include all components of remuneration.
• Independent oversight body: An external auditor, such as the European Court of Auditors or a dedicated equality ombudsperson, should be empowered to verify pay data and investigate systemic disparities.
• Revision of the Staff Regulations: The grading and promotion system should be reviewed for gendered effects, with particular attention to the criteria for allowances and the design of appraisal exercises.
• Extension of the Pay Transparency Directive: The EU institutions should voluntarily commit to applying the directive’s standards to their own workforce, pending a formal legal amendment.

FAQ: The Gender Pay Gap in EU Institutions

What is the current gender pay gap in the European Commission?

The European Commission’s most recent diversity report indicates an unadjusted pay gap of approximately 10% for officials, based on basic salary. This figure excludes contract agents, temporary staff, and allowances, meaning the true gap is likely higher. The Commission has not published a comprehensive pay gap analysis that includes all remuneration components and staff categories.

Why doesn’t the EU’s Pay Transparency Directive apply to its own institutions?

The Pay Transparency Directive was adopted under Article 157(3) TFEU, which provides the legal basis for measures to ensure equal pay between women and men in the member states. The EU institutions are governed by the Staff Regulations, adopted under Article 336 TFEU. The Commission and Council have taken the view that the directive does not automatically apply to the institutions, and no separate legislative proposal has been made to extend its provisions. This creates a regulatory gap that the institutions have so far declined to close voluntarily.

How do allowances contribute to the gender pay gap in EU institutions?

Allowances such as the expatriation allowance, household allowance, and dependent child allowance can add 20–30% to an official’s basic salary. Their allocation depends on personal circumstances that are shaped by gendered patterns of mobility, caregiving, and household composition. Because the institutions do not publish gender-disaggregated data on allowance distribution, the precise contribution of allowances to the overall pay gap is unknown. This lack of transparency prevents meaningful analysis and accountability.

What can individual staff members do if they suspect pay discrimination?

Staff members can file a complaint under Article 90 of the Staff Regulations and, if the complaint is rejected, bring an action before the EU Civil Service Tribunal. However, the burden of proof lies with the complainant, and systemic challenges are difficult to mount through individual cases. Staff committees and trade unions can provide support, but their power to negotiate pay structures is limited. The most effective route to systemic change remains political pressure on the institutions to reform their own rules.

This article is part of an ongoing series on the forensic analysis of EU institutional design and its gendered outcomes. The next instalment will examine the representation of women in the EU’s security and defence agencies, where the pay gap intersects with occupational segregation in particularly stark ways.
