Overtime can widen a gender pay gap even when hourly base rates are equal. Recital 21 of Directive (EU) 2023/970 expressly identifies overtime compensation as an example of complementary or variable pay. Employers should therefore examine not only overtime amounts paid, but also who was eligible for overtime, who was offered additional hours, who worked those hours, which premium rates applied and whether scheduling or approval practices affected access. Article 9 requires covered employers to report gender pay gap information for complementary or variable components, so overtime should be identifiable in compensation data where it materially contributes to those components.

Overtime Compensation Is Expressly Included in the Pay Framework
Recital 21 of Directive (EU) 2023/970 lists overtime compensation among the examples of complementary or variable components of pay. That means an equal-pay or transparency review should not automatically exclude overtime because it is irregular or depends on additional hours. The legal concept of pay is broader than contractual base salary. Employers should identify overtime hours, premium amounts and related allowances separately enough to understand how they affect total earnings. National law and collective agreements still determine important details such as entitlement, working-time limits and applicable rates, so the Directive should be read together with the rules that govern overtime in the relevant jurisdiction.
Equal Base Rates Can Still Produce Different Annual Earnings
Two workers can receive the same basic hourly rate but end the year with different total pay because one worked substantially more overtime. That difference is not automatically an equal-pay violation. Operational need, working patterns, voluntary availability or role requirements may explain it. The employer should nevertheless understand the source of the difference rather than assuming the final total is self-explanatory. A pay-equity review should separate base pay, overtime hours, overtime premium and any other variable components so that the organisation can see whether the gap comes from rate, opportunity, hours worked or another factor.
Access to Overtime Is an Important Equity Question
The amount paid is only one part of overtime analysis. Employers should also examine how overtime opportunities are distributed. If managers repeatedly offer premium shifts or additional hours to the same workers, differences in total pay can become embedded even when the overtime rate itself is neutral. A defensible process should explain eligibility, how opportunities are communicated, whether workers can volunteer, how competing requests are resolved and when managers can make exceptions. Patterns can then be tested within relevant worker categories to determine whether one sex receives systematically greater access to overtime-generating work.
Scheduling Practices Can Influence Overtime Outcomes
Overtime opportunity can also be shaped indirectly by scheduling. Certain shifts, locations, travel requirements or short-notice callouts may create more access to premium hours than others. Employers should therefore look beyond payroll totals and connect overtime with roster data where useful. The goal is not to force identical overtime hours for every worker, but to understand whether the scheduling system uses objective operational criteria and whether comparable workers have a fair opportunity to access additional paid work. If structural patterns appear, the employer can review staffing, rotation or volunteering processes without treating every difference as proof of discrimination.
Article 9 Requires Visibility Into Variable Components
Article 9 requires covered employers to report the gender pay gap and median gender pay gap in complementary or variable components, the proportion of women and men receiving those components, and category-level differences broken down between basic salary and complementary or variable components. Where overtime is a material variable component, payroll systems should preserve enough detail to identify it reliably. Combining overtime with unrelated bonuses or allowances in one opaque field can make analysis harder. A clear compensation taxonomy supports reporting, investigation and explanation of any gap that appears.
An Overtime Audit Should Compare Opportunity, Hours and Premiums
A useful overtime audit can compare eligibility, opportunities offered, hours accepted, hours worked, base rates and premium payments within comparable worker groups. Employers can then test whether differences correlate with shift patterns, job requirements, voluntary choices or other objective factors. Manager approvals and manual adjustments should also be reviewed where they materially affect outcomes. The methodology should document the period analysed and the treatment of absences or atypical schedules. This creates a repeatable evidence trail and helps the organisation distinguish an explainable operational pattern from a difference that requires corrective action or deeper equal-pay review.
Frequently Asked Questions
Does overtime count as pay under the EU Pay Transparency Directive?
Yes. Recital 21 expressly identifies overtime compensation as an example of a complementary or variable component of pay.
Does a difference in overtime earnings automatically mean unequal pay?
No. Differences can have objective explanations, but employers should examine both overtime rates and access to overtime opportunities before deciding that the gap is fully explained.
Should overtime be separated from base salary in pay analysis?
Yes where possible. Separating base pay from overtime makes it easier to identify whether a gap arises from salary rates, additional hours, premium rates or access to overtime opportunities.
