Joint pay assessment — what triggers Article 10 and what it actually involves

Article 10 is the article HR teams hope to never engage with. It fires when a per-category gap above 5% cannot be explained on objective gender-neutral grounds. Once it fires, it consumes more operational time than the entire reporting cycle that produced it.

Most preparation focuses on Article 9 (the report). Article 10 (the follow-through) lives downstream, often unrehearsed, often discovered at the worst moment to discover anything. The inputs Article 10 demands are the same inputs that should already exist when the report is produced — but only the report-side preparation typically receives the attention.

The trigger condition and the process are worth understanding before the report runs. A company that builds for Article 9 and discovers Article 10's requirements at trigger time is building twice.

What actually triggers Article 10

The condition is stated in Article 10, paragraph 1 of Directive 2023/970, with two parts. Both must hold for the assessment obligation to fire.

The threshold operates per category, not overall. A company with a 2% overall gap can still trigger Article 10 if one specific category of equal work shows a 6% gap that the available rationale does not explain. The aggregate masks; the per-category breakdown surfaces.

The "objective and gender-neutral criteria" clause is what distinguishes a triggered assessment from a non-triggered one. Tenure, performance grade, geographic adjustment, role seniority within a level — all valid explanatory factors when documented and applied consistently across genders. The gap remaining after these factors is the residual that Article 10 examines.

Who participates

The "joint" in joint pay assessment is the directive's term for participation. The assessment is not the employer's solo analysis; it is conducted in cooperation with worker representatives.

Three categories of participants:

• Employer's representatives. Typically HR leadership, sometimes joined by Legal and Finance. The employer prepares the data, the methodology, and the proposed analysis.
• Worker representatives. Defined by national law — in most member states, this is the works council, union representative, or elected employee delegates. Where no formal representation exists, the directive specifies alternative consultation mechanisms.
• Labour authority observers (in some member states). National transposition may designate a labour inspectorate or monitoring body to observe or facilitate.

The participation is not advisory. Worker representatives have access to the underlying data, the methodology, and the calculations. They can challenge each. The assessment's conclusion is reached jointly — neither side delivers it unilaterally.

The four phases of the assessment

What needs to exist before the assessment starts

The employer that engages an Article 10 assessment having only the Article 9 report on hand is at a structural disadvantage. The questions worker representatives will ask are not in the report. They are in the layer beneath it.

Three documents that the employer benefits from having ready:

1. The job evaluation methodology. How categories of equal work or work of equal value were constructed. The four-dimension framework (skills, effort, responsibility, working conditions) applied in writing.
2. The pay-setting rationale catalogue. For each pay decision in the affected category — initial offer, increment, promotion-linked uplift — the documented criteria that determined the position. Performance grades, tenure tables, geographic adjustments, all observable in the record.
3. The compression and outlier register. Cases where an employee sits above or below the documented band, with the rationale attached. These are the cases worker representatives will challenge first.

What prevents Article 10 in practice

The fastest way to never need an Article 10 assessment is to make sure every per-category gap above 5% has a documented, gender-neutral explanation by the time the report is published. The structural inputs — categories, methodology, rationale — are what produce that explanation.

Three preventive practices, observable in the documentation:

• Quarterly per-category gap reviews. Run the calculation outside the annual reporting cycle. Surface gaps before they hit the 5% threshold; remediate inside the regular pay review process, not under Article 10's joint pressure.
• Documented offer rationale. Every offer extended above or below the role band has a written justification, on file, gender-neutral, applied consistently. This is the catalogue Article 10 will read.
• Compression and outlier auditing. Identify and explain (or remediate) cases where pay positioning is anomalous. The auditing produces the register that an Article 10 assessment uses as its starting point.

Article 10 is the cost of being unprepared. The preparation is the work that would have prevented the trigger.

Survey-based market data reports the per-category aggregate as it stood last year. The Article 10 trigger condition is evaluated against this year's data, on the company's own methodology. Survey context is not a trigger detector.

Where the diagnostic starts

Before Article 9 runs, before Article 10 can trigger, the question is whether the structural inputs exist. The job evaluation methodology, the pay-setting rationale, the compression auditing — these are the inputs the joint assessment will examine if it fires.

The ReadinessCheck™ surfaces whether those inputs are in place — by axis of the directive's principal obligations, without requiring any salary data. It does not run the Article 9 calculation. It tells you whether Article 10 is a manageable conversation if it triggers.
