Under Article 18 of Directive (EU) 2023/970, a worker does not always have to prove every element of pay discrimination from the outset. Once the worker establishes facts from which direct or indirect pay discrimination may be presumed, the respondent must prove that there has been no such discrimination. National courts and authorities apply the procedural detail, but the Directive is designed to prevent workers from carrying an impossible evidential burden where key pay information is controlled by the employer.

The Worker Must First Establish Facts Supporting a Presumption
Article 18 does not mean that every allegation automatically forces an employer to disprove discrimination. The worker must first establish facts before a competent authority or national court from which direct or indirect pay discrimination may be presumed. What facts are sufficient depends on the case and national procedure. Relevant material can include pay differences, comparator information, job-value evidence, inconsistent pay criteria, statements, statistical patterns or failures in transparency processes. The purpose is to create a workable evidential threshold without requiring a worker to possess all of the employer's internal records before a claim can proceed.
The Respondent Then Has to Prove There Was No Pay Discrimination
Once the presumption threshold is met, the burden moves to the respondent. The employer or other respondent must prove that the pay difference or challenged practice was not direct or indirect discrimination. That often requires evidence of objective, gender-neutral criteria and consistent application. A bare assertion that the difference was based on performance, experience or market conditions may be insufficient if the employer cannot show how that factor was assessed and why it explains the actual difference. Documentation therefore matters as much as the stated reason.
Direct and Indirect Discrimination Are Both Covered
Article 18 expressly refers to direct and indirect discrimination in relation to pay. Direct discrimination concerns less favourable treatment because of sex. Indirect discrimination can arise where an apparently neutral rule, criterion or practice places one sex at a particular disadvantage unless it is objectively justified by a legitimate aim and the means are appropriate and necessary under the applicable law. Employers reviewing pay systems should therefore look beyond overtly different treatment. Pay criteria, progression rules and bonus structures can create patterns that require explanation even when the wording of the policy is neutral.
Pay Transparency Makes Relevant Facts Easier to Identify
The Directive's transparency rights support enforcement because workers can obtain information about individual pay levels and average pay levels for categories of workers performing the same work or work of equal value. Reporting can also reveal patterns that deserve closer examination. Transparency does not prove discrimination by itself. It can, however, provide facts that help a worker assess whether a claim is plausible and can help a court or authority understand the structure of the dispute. Employers should therefore expect their own transparency outputs to be read alongside pay-setting records.
The Burden Rule Rewards Defensible Pay Governance
An employer is better placed to meet the shifted burden when it can reconstruct why a pay decision was made. Useful evidence includes approved salary ranges, job evaluation records, objective progression criteria, performance evidence, market data used at the time, collective-agreement provisions and consistent records of exceptions. The aim is not to create documents after a claim appears. Explanations created retrospectively can be less persuasive than contemporaneous evidence showing that the stated criteria were actually used. Governance should therefore be designed before disputes arise.
National Procedure Still Determines How the Rule Operates in Court
The Directive sets the minimum EU standard, but Member States implement it through their own judicial systems. Rules on pleadings, disclosure, admissibility, expert evidence and the standard used to assess proof remain matters of national law, subject to EU requirements. Employers and workers should therefore avoid assuming that a burden-of-proof rule operates identically in every country. The substantive principle is common, while the litigation mechanics may differ. Local legal advice can be important once a formal claim has started.
Frequently Asked Questions
Does the worker have to prove discrimination completely before the burden shifts?
No. Article 18 requires facts from which discrimination may be presumed. Once that threshold is met, the respondent must prove there was no direct or indirect pay discrimination.
Can objective pay factors rebut the presumption?
Potentially yes, if the employer can show that the factors are legitimate, gender neutral and actually explain the difference under the applicable law.
Does Article 18 replace national court procedure?
No. Member States apply the burden rule within their national judicial systems.
