Collective agreements can strongly affect how comparable work is identified because they may define grades, classifications, pay scales, allowances and progression rules. Article 4 of Directive (EU) 2023/970 requires objective, gender-neutral criteria and provides for those criteria to be agreed with workers' representatives where they exist. Article 19 also recognises that agreements regulating pay across several employers may form part of a single source establishing relevant pay conditions. However, a collectively agreed structure is not automatically lawful simply because it was negotiated. Classifications and pay rules still need to comply with the principle of equal pay for equal work or work of equal value.

Collective Agreements Often Define the Comparison Framework
Collective agreements may establish job families, grades, salary scales, progression points, allowances and promotion rules. These structures can give employers and workers a common language for assessing whether roles are the same or of equal value. Where the classification system is robust and gender-neutral, it can make equal-pay analysis more consistent and easier to explain.
Workers' Representatives Have an Express Role Under Article 4
Article 4 requires pay structures to enable comparison on objective, gender-neutral criteria agreed with workers' representatives where such representatives exist. This makes consultation more than a purely administrative exercise. Employers should be able to show how the criteria operate, how roles are classified and how potentially biased factor definitions or weightings are identified and corrected.
A Collective Agreement Can Be Relevant to the Single-Source Test
Recital 29 and Article 19 recognise that workers may be comparable beyond one employer where pay conditions are attributable to a single source. An agreement governing pay across several employers can be relevant to that analysis. The exact legal effect depends on the structure of the agreement, who sets the relevant pay elements and national law, but employers should not assume that separate legal entities automatically end the comparator inquiry.
Negotiated Pay Structures Can Still Contain Historic Bias
Collective bargaining does not eliminate the possibility of indirect discrimination or historic undervaluation. Older classification systems may reward factors associated with traditionally male-dominated jobs while giving less value to communication, care, coordination or emotional demands. Article 4's gender-neutral methodology and soft-skills requirement are therefore relevant even where a structure has long-standing collective legitimacy.
Employers Should Document How Agreement Rules Affect Pay
Where a pay difference is linked to a collective agreement, the employer should identify the relevant provision, classification rule, allowance or progression mechanism and explain how it applies. A general statement that 'the collective agreement requires it' may not be enough if the underlying structure itself produces an unexplained sex-based difference. Documentation should connect the agreement rule to objective, gender-neutral criteria and the actual work performed.
Frequently Asked Questions
Does a collective agreement decide whether jobs are of equal value?
It can provide important classification evidence, but the underlying equal-pay test still requires objective, gender-neutral assessment of work value.
Can a collective agreement support comparisons across employers?
Potentially yes. Article 19 recognises comparisons where a single source establishes relevant pay conditions, and agreements applying across employers can be relevant to that analysis.
Is a negotiated pay structure automatically compliant with equal-pay law?
No. A collectively agreed structure must still comply with the principle of equal pay and should not embed direct or indirect sex discrimination.
