Fixed annual day-rate arrangements: applying the wrong collective agreement does not render the arrangement void

Le forfait annuel en jours est un mécanisme d’organisation du temps de travail très prisé des entreprises pour sa souplesse, mais qui nourrit un contentieux abondant, en raison des conditions de validité strictes qu’il impose. A ruling of the Cour de cassation dated 25 March 2026 (n° 24-22.129) provides an important clarification: where an employer has applied a fixed annual day-rate arrangement (forfait annuel en jours) on the basis of a collective agreement that was not actually applicable to its business activity, this error does not automatically render the arrangement void, provided that the collective agreement actually applicable also authorises the arrangement.

Fixed annual day-rate arrangements: overview of the legal framework and validity requirements

A derogatory working time arrangement

The fixed annual day-rate arrangement is a regime that derogates from the ordinary rules governing working time. The employee’s working time is measured in days per year rather than in hours, which in principle excludes the application of the rules on overtime and maximum weekly working hours. The arrangement offers genuine flexibility for business organisation, but it is subject to cumulative validity requirements, non-compliance with which exposes the employer to significant litigation risk.

Validity requirements for the fixed annual day-rate arrangement

To be valid, a fixed annual day-rate arrangement must satisfy several requirements set out in Articles L. 3121-58 et seq. of the Labour Code. It must first be authorised by a company-level agreement or an extended collective agreement, which must in particular set the annual cap on days worked. It may only apply to employees who enjoy genuine autonomy in organising their working time and whose working hours cannot be determined in advance. Finally, it must be accompanied by an effective monitoring of the number of days worked and at least one annual review meeting covering workload, work-life balance, and remuneration.

Key point

The absence, or purely formal conduct, of the mandatory annual review meeting, as well as the absence of effective monitoring of days worked, are breaches that courts regularly sanction by declaring the arrangement void, with the consequence of reverting to the ordinary working time rules and ordering the payment of overtime over several years.

Abundant litigation, often avoidable

Fixed annual day-rate arrangements are one of the most frequent sources of employment tribunal disputes in French labour law. Recurring breaches include: inapplicable or non-extended collective agreements, absence of monitoring of days worked, non-existent or purely formal annual review meetings, and application of the arrangement to employees lacking sufficient autonomy. Any one of these deficiencies may suffice to render the arrangement void and give rise to entitlement to overtime pay, sometimes covering three years of arrears.

Fixed annual day-rate arrangement and wrong collective agreement: ruling n° 24-22.129 of 25 March 2026

The facts: 218 days based on the wrong collective agreement

In the case before the Cour de cassation, a company had implemented a fixed annual arrangement of 218 days on the basis of a collective agreement that did not, in fact, correspond to its principal business activity. The collective agreement actually applicable did authorise the use of a fixed annual day-rate arrangement, but capped it at 214 days per year, four days fewer than the arrangement actually applied.

The employee’s claim: voidness of the arrangement and overtime arrears

The employee argued that this error in the conventional reference rendered the arrangement entirely void. She drew the consequence typical of this type of dispute: a reversion to the ordinary working time rules and a claim for payment of overtime worked beyond 35 hours per week, potentially representing several years of salary arrears.

What was at stake

The voidness of a fixed annual day-rate arrangement carries considerable financial consequences for the employer: it gives rise to entitlement to payment for all hours worked beyond 35 hours per week, subject to the three-year limitation period. The financial exposure may amount to several tens of thousands of euros per employee concerned.

The Cour de cassation’s ruling: no voidness, but a limited salary top-up

The Cour de cassation did not follow the employee’s reasoning. It held that an error in the conventional reference does not render the arrangement void, provided that the collective agreement actually applicable to the company also authorised the use of a fixed annual day-rate arrangement. In other words, the employer’s error was an error as to the cap, not an error of principle.

The consequence is proportionate to the irregularity identified: the employee may only claim a top-up payment at the enhanced overtime rate in respect of days worked beyond the number of days authorised by the collective agreement actually applicable, that is, the four days in excess of the 214-day cap.

Fixed annual day-rate arrangements: scope and lessons of the ruling

A solution grounded in proportionality of sanctions

The Cour de cassation’s decision reflects a logic of proportionality between the irregularity identified and the sanction imposed. The employer had complied with the substantive requirement, relying on a conventional basis authorising the fixed day-rate arrangement, but had applied the wrong cap. Total voidness of the arrangement, with its massive financial consequences, would have been a disproportionate sanction for this error of reference.

A clear distinction: error of principle vs. error as to the cap

The ruling implicitly establishes a useful distinction. Where no applicable collective agreement authorises the fixed day-rate arrangement, voidness is compelled: the employer has failed to satisfy a substantive condition. By contrast, where the collective agreement actually applicable does authorise the arrangement but the employer has applied an incorrect cap by relying on the wrong instrument, the sanction is limited to regularising the identified excess.

Caution

This solution only applies where the collective agreement actually applicable authorises the fixed annual day-rate arrangement. If that is not the case, or if the other validity requirements (monitoring of days worked, annual review meeting, employee autonomy) are not satisfied, the arrangement remains fully exposed to voidness.

What the ruling does not cover

The scope of this ruling should not be overstated. The Cour de cassation is not validating poorly structured arrangements: it is ruling on a very specific scenario, an error in the conventional reference in a context where the arrangement remains authorised under the applicable law. All other grounds for voidness, absence of an annual review meeting, failure to monitor days worked, application to an ineligible employee, remain intact and continue to generate significant litigation.

Fixed annual day-rate arrangements: key takeaways for employers and HR teams

Verifying the collective agreement actually applicable

The first area of vigilance is documentary: ensuring that the collective agreement relied upon by the company does indeed correspond to its principal business activity, as defined by the APE code and the conventional classification. An error of reference, even in good faith, may expose the company to a salary top-up claim in respect of excess days and, in more serious cases, to voidness of the arrangement if the collective agreement actually applicable does not authorise it.

Checking the applicable day cap

The statutory cap is set at 218 days under Article L. 3121-64 of the Labour Code, but a collective agreement may provide for a lower cap, as was the case in the ruling of 25 March 2026 with a cap of 214 days. Applying an arrangement beyond the conventional cap exposes the employer to an enhanced-rate salary top-up claim for each excess day.

Securing monitoring and annual review meetings

Regardless of the robustness of the conventional basis, a fixed annual day-rate arrangement cannot withstand the absence of effective monitoring or the failure to hold annual review meetings. These obligations must be documented, dated, and retained: monthly records of days worked, written accounts of review meetings, and a traceable record of exchanges on workload constitute the essential evidence in the event of litigation.

Not overlooking employee eligibility

A fixed annual day-rate arrangement may only apply to employees falling within the categories covered by the agreement or collective convention, executives enjoying autonomy in organising their working time, or employees whose working hours cannot be determined in advance. Applying a fixed day-rate arrangement to an ineligible employee remains an independent ground for voidness, irrespective of any question relating to the cap or the conventional reference.

Checklist: 8 points to verify to secure a fixed annual day-rate arrangement

  1. Does the collective agreement actually applicable to the company’s principal business activity authorise the use of a fixed annual day-rate arrangement?
  2. Is the annual day cap applied consistent with that provided for by this collective agreement (and not by an incorrectly referenced agreement)?
  3. Is the individual fixed-rate agreement formally set out in writing in the employment contract or a signed addendum?
  4. Does the employee fall within the categories eligible for the fixed day-rate arrangement (genuine autonomy, indeterminate working hours)?
  5. Is effective monitoring of the number of days worked in place and documented on a monthly basis?
  6. Is the mandatory annual review meeting held, formalised in writing, and does it cover workload, work-life balance, and remuneration?
  7. Are any overruns of the cap identified and regularised within the required timeframes?
  8. Is the file in a condition to be produced in the event of an audit or dispute (agreement, monitoring records, review meeting minutes)?

Fixed annual day-rate arrangements: frequently asked questions for an employment lawyer


This is one of the situations most frequently submitted to an employment lawyer specialising in working time matters. The absence of an annual review meeting, or its purely formal conduct, without any genuine examination of workload, constitutes a breach by the employer of its statutory obligations. The Cour de cassation’s case law is settled on this point: such a deficiency renders the fixed annual day-rate arrangement void. The employee then reverts to the benefit of the ordinary working time rules and may claim payment for all hours worked beyond 35 hours per week, subject to the three-year limitation period. A precise analysis of the file, contracts, addenda, written exchanges, payslips, is essential to assess the potential top-up amount and the strength of the claim.


The first step is to conduct a legal audit of the fixed day-rate arrangements in place within the company, with the assistance of an employment lawyer. This audit covers four areas: compliance of the conventional basis, adherence to the annual day cap, existence and quality of monthly monitoring of days worked, and traceability of annual review meetings. In the vast majority of files reviewed, at least one of these points presents a vulnerability. Early identification makes it possible to regularise the position before any litigation arises, which is always less costly than employment tribunal proceedings.


The absence of a written individual agreement is an independent ground for voidness of the fixed annual day-rate arrangement, separate from any question relating to the collective agreement or the annual review meetings. The individual fixed-rate agreement must be formalised in writing, in the initial employment contract or in an addendum signed by the employee. An employment lawyer can assess whether this situation gives rise to a claim for overtime arrears and assist the employee in pursuing an amicable or contentious resolution. For the employer, regularisation by way of an addendum is only possible for the future: it does not cover prior periods.


This situation corresponds precisely to the one decided by the Cour de cassation on 25 March 2026. Total voidness of the arrangement is not established, the Court held that an error in the conventional reference does not call into question the validity of the arrangement, provided that the collective agreement actually applicable also authorises it. However, the four excess days give rise to a top-up payment at the enhanced overtime rate. Over the three-year limitation period, and depending on the level of remuneration, the amount may be significant. An employment lawyer can calculate the exact top-up due and bring the claim against the employer or before the employment tribunal.


As early as possible, and ideally before taking any formal step. Fixed annual day-rate arrangement issues are technically complex: they involve collective labour law, working time law, and an extensive body of Cour de cassation case law. A consultation with an employment lawyer makes it possible to quickly assess the strength of the file, identify established breaches, estimate the potential top-up amounts, and choose the most appropriate strategy, amicable negotiation, formal notice, or referral to the employment tribunal. For employers, this consultation is equally useful as a preventive measure: it is always preferable to secure a vulnerable arrangement before an employee takes the initiative of bringing a claim.

Fixed annual day-rate arrangements: rigour in implementation remains the best protection

The ruling of 25 March 2026 provides a measured solution to a situation involving an error in the conventional reference, but it should not lead employers to relax their vigilance. The validity of a fixed annual day-rate arrangement rests on a set of cumulative requirements, each of which constitutes an independent litigation risk. Verifying the correct collective agreement, checking the caps, documenting monitoring, and formalising annual review meetings: these remain essential reflexes.
