Reference Decision: cc • No. 07-42.799 • 2008-10-24
Imagine the scene: at Sophia-Antipolis, an employee of a biotechnology company checks his recovery day balance. He has been accumulating RTT for months, the result of his overtime. But when he reads his collective agreement, he discovers that he is also entitled to seniority leave. Can he add the two together? His employer, however, believes that these days are already included in the company agreement. A classic conflict… and an expensive one.
Every owner or employer wonders: how do you know which rule applies? The answer was given by the Court of Cassation in a ruling of 24 October 2008 (No. 07-42.799): recovery days and seniority leave have neither the same cause nor the same object. In other words, they cannot be lumped together for comparison. This ruling is a compass for all those juggling between a collective agreement and a company agreement.
But what exactly does this change? Let's delve into the facts, the judges' reasoning, and above all, what you need to do practically to avoid a dispute.
The Facts: A Story That Happens Every Day
Mr. X, an employee of a service company in Sophia-Antipolis, had been benefiting for years from a company agreement on the organisation and reduction of working time (ARTT). This agreement granted him recovery days in return for hours worked beyond the legal working time. In parallel, the collective agreement for the metallurgy industry (applicable to his sector) provided for additional seniority leave: 1 day after 10 years, 2 after 15, etc.
During a review of his entitlements, Mr. X realises that his employer is not granting him these seniority days, on the grounds that the recovery days under the company agreement are more favourable. According to the employer, the total number of paid non-working days (RTT + statutory paid leave) is higher than that provided for by the collective agreement. He therefore considered that the most favourable provision was the company agreement, and that there was no need to add the seniority leave.
Mr. X takes the case to the Grasse industrial tribunal, which rules in his favour. The appeal court (Aix-en-Provence) confirms: it compares the overall paid non-working time (RTT + paid leave) and finds the company agreement less favourable. The employer appeals to the Court of Cassation.
The Court of Cassation quashes the appeal judgment on 24 October 2008, on the grounds that the lower courts compared benefits of a different nature: recovery days (consideration for actual work) and seniority leave (benefit linked to seniority) have neither the same cause nor the same object. They cannot therefore be aggregated to determine the most favourable provision.
The Reasoning of the Court — Analysed
The Court of Cassation relies on the general principle of labour law: benefits having the same object or same cause cannot be cumulative; only the most favourable of them may be applied. But caution: for comparison, the benefits must be of the same nature.
In this case, recovery days (RTT) are the consideration for hours worked beyond the legal or contractual working time. Their cause is the additional work, their object is to compensate for this work with rest. Seniority leave, on the other hand, is a benefit granted in recognition of the employee's loyalty to the company. Their cause is seniority, their object is to reward this loyalty with additional rest days.
The Court concludes that these two types of days have neither the same cause nor the same object. Consequently, they cannot be compared globally. One cannot say that the company agreement is more favourable because it gives more non-working days in total (RTT + paid leave) than the collective agreement (seniority leave + paid leave). The seniority leave must be compared alone with the provisions of the company agreement dealing with the same object (for example, a seniority bonus or seniority leave days if the agreement provides for them).
In short, the appeal court made a methodological error: it added apples and oranges. The Court of Cassation reminds that each benefit must be examined separately, and that the favour principle (Article L.2251-1 of the Labour Code) applies only between benefits of the same nature.
What few people know: this decision confirms established case law (e.g., Cass. soc., 10 May 2006, No. 04-46.694). It is therefore not a reversal, but a firm reminder to lower courts not to mix categories.
What This Changes for You — Practically
For the employer or HR manager: you must check that your company agreement grants rights at least equivalent to the collective agreement, benefit by benefit. If you remove seniority leave by replacing it with RTT, you risk being ordered to pay damages. Example: an employee at Le Cannet accumulates 12 RTT days per year. The collective agreement provides for 3 seniority days after 20 years. You cannot say that 12 > 3, so it's more favourable. You need to see whether the company agreement itself provides an equivalent benefit to seniority leave (for example, a bonus).
For the employee: if you believe your employer is not granting you a benefit provided for by the collective agreement on the pretext that the company agreement is more favourable, ask for a detailed comparison, benefit by benefit. If they aggregate, they are probably wrong. You can claim the untaken seniority days, subject to a limitation period of 3 years (Article L.3245-1 of the Labour Code).
For trade unions and employee representatives: when negotiating a company agreement, ensure that each benefit of the collective agreement is taken over or substituted by a benefit of the same nature. A "globalisation" clause (global comparison) would be ineffective.
undefined, I have come across cases where an employer in Sophia-Antipolis had removed seniority leave by integrating it into a flat-rate days package. Result: 3 years of back pay for 15 employees, totalling approximately €45,000 in damages.
Four Tips to Avoid This Type of Dispute
- Conduct an audit of your collective agreements: list all benefits provided by your collective agreement (seniority leave, bonuses, allowances) and compare them one by one with your company agreement. If a benefit is not taken over, check whether there is a benefit of the same nature that compensates for it.
- Draft precise substitution clauses: if you wish to replace seniority leave with RTT, state clearly that these RTT have the same object and the same cause. Otherwise, the substitution will be ineffective.
- Inform employees individually: provide each employee with a summary document of the applicable benefits (collective agreement and company agreement) specifying which is the most favourable for each right.
- If in doubt, consult a lawyer lawyer: legal advice upstream costs far less than a trial. A 30-minute initial consultation (€45) can save you months of proceedings.

Further Analysis: Related Case Law and Developments
This decision is part of a consistent line of the Court of Cassation. As early as 2006 (decision No. 04-46.694), it had ruled that recovery days and seniority leave are of a different nature. More recently, in a ruling of 13 March 2013 (No. 11-27.872), it specified that the comparison must be made "benefit by benefit", and not globally.
However, be aware: since the 2016 Labour Law (Law No. 2016-1088), the company agreement can now derogate from the collective agreement in many areas, even to the employee's disadvantage, unless the collective agreement expressly prohibits it. But for seniority leave, the collective agreement often retains a mandatory character ("locking" clauses). So you need to check the wording of your collective agreement.
The trend of the courts is clear: they are very strict on the method of comparison. Employers who try to bury benefits in a "global package" are systematically ordered to pay damages.
Key Points to Remember
FAQ:
Q: Can I cumulate recovery days and seniority leave?
A: Yes, because they do not have the same cause. Recovery days compensate for overtime, seniority leave rewards your loyalty.
Q: Can my employer remove seniority leave if the company agreement gives more RTT?
A: No, not without an express substitution. They must compare benefit by benefit. RTT does not automatically replace seniority leave.
Q: What are the time limits for claiming untaken seniority leave?
A: 3 years from the day you became aware of your rights (Article L.3245-1 of the Labour Code).
Q: What should I do if my employer refuses to grant me seniority leave?
A: Bring the case before the industrial tribunal. Gather evidence (collective agreement, company agreement, payslips).
Q: Does this decision apply to all sectors?
A: Yes, the principle is general. But each collective agreement may have specificities. Check yours.
