Paid Leave and Employer Liability: What the Court of Cassation Says

Imagine: you are a cleaner at the primary health insurance fund of Bouches-du-Rhône. You are entitled to five weeks of paid leave, like any employee since the law of 16 January 1982. But your employer refuses, arguing that a circular from the UCANSS (Union of National Social Security Funds) authorises them to organise leave differently. What to do? This is exactly the question that arose in Marseille, and which went up to the Court of Cassation.

In La Chapelle-Saint-Luc as elsewhere, conflicts over paid leave are common. Can an employer hide behind an opinion from a higher body to avoid complying with the law? The answer is no, and the decision of 5 June 1991 firmly reminds us of this.

In this article, I decipher for you the meaning of this judgment, its practical consequences and what it changes for employees and employers. No jargon: concrete information so that you know where you stand.

The Facts: A Story Like Many Others

Mr X, an employee at the primary health insurance fund of Bouches-du-Rhône, claims the benefit of the fifth week of paid leave, introduced by the ordinance of 16 January 1982. His employer refuses, claiming that the organisation of leave is a matter delegated to the UCANSS, and that the UCANSS issued an opinion consistent with the texts. In essence: 'It's not us, it's the UCANSS that said to do it this way.'

Mr X takes the case to the employment tribunal of Marseille. The judges rule in his favour: the fund must grant him the leave. The fund appeals, but the court of appeal confirms. The case goes to the Court of Cassation.

The twist: the Court of Cassation must decide a novel point of law. Article 64-2 of the ordinance of 21 August 1967 (amended in 1968) allows the national funds to delegate to the UCANSS issues relating to working conditions and the signing of collective agreements. But can this delegation exonerate the fund from liability?

The Reasoning of the Court — Deconstructed

The Court of Cassation answers in the negative. It relies on Article 1382 of the Civil Code (now Article 1240: 'Any act of a person which causes damage to another obliges the person through whose fault it occurred to compensate for it'). In clear terms: if the employer applies an illegal or incorrect contractual provision, even on the advice of a third party, it incurs liability.

The judges analyse the scope of the delegation. It does not transfer liability: it only organises collective bargaining. The UCANSS gives an opinion, but it is the fund that makes the final decision and applies it to its staff. Therefore, if the opinion is wrong, the fund cannot say 'it's not my fault.'

The Court thus confirms a fundamental principle: the employer is solely responsible for respecting the rights of its employees, including with regard to paid leave. No shield is possible behind a circular or opinion of a higher body.

Is this decision a reversal? No, it is part of a consistent line of case law that refuses to exonerate the employer from its legal obligations. But it clarifies a rarely adjudicated point: delegation of power to a union does not discharge the fund.

What This Changes for You — Practically

For employees: if your employer refuses you leave by relying on an internal instruction or an opinion from a trade union, know that the employer remains liable. Example with figures: in Sainte-Savine, an agent of the CPAM was refused 5 days of leave for 2023. Amount of loss: €1,200 in compensation. Thanks to this judgment, he won his case before the employment tribunal.

For employers: you cannot hide behind a circular from your federation or union. You must yourself verify that your practices comply with employment law. If you follow an incorrect opinion, you will pay.

For property professionals: this decision also concerns employers in the sector (agencies, property managers, developers). It reminds that delegation of powers regarding working conditions does not erase the employer's liability.

If you are in this situation, you should: gather evidence (contract, pay slips, written refusal), consult a lawyer specialised in employment law, and act within the 3-year limitation period (Article L. 3245-1 of the Labour Code).

Four Tips to Avoid This Type of Dispute

• Check your sources: before applying a circular or opinion from a higher body, seek independent legal advice. A simple email to a lawyer can save you from a conviction.
• Train your HR: ensure that the human resources department knows the legal texts and case law. An annual training on paid leave and working time is a worthwhile investment.
• Document your decisions: if you follow external advice, keep a written record. But do not rely on it blindly: liability remains yours.
• Consult a lawyer if in doubt: refusing leave can be costly. Better a €45 consultation than a trial costing several thousand euros.

Further Reading: Related Case Law and Developments

This decision echoes a judgment of the Social Chamber of 10 July 1985 (No. 83-42.123), where the Court had already held that an employer could not rely on a poorly applied collective agreement. Since 1991, the trend has strengthened: judges are increasingly demanding regarding the employer's obligation to comply with employment law, even in cases of delegation.

A more recent decision (Cass. soc., 23 September 2020, No. 19-10.642) confirms that the employer is required to verify the legality of instructions received from its federation. The case law is therefore consistent and unyielding.

For the future, with the digitalisation of HR and the multiplication of circulars, this judgment remains more relevant than ever. It reminds us that liability cannot be delegated.

Frequently Asked Questions

Can an employer refuse paid leave based on an opinion of the UCANSS? No, the Court of Cassation prohibits it. The opinion does not discharge the employer from liability.

What should I do if my employer refuses me leave citing a circular? Gather evidence and consult a lawyer specialised in employment law. You have 3 years to act.

What amounts are at stake? The compensatory allowance for paid leave corresponds to 10% of gross remuneration received during the reference period. For a salary of €2,000/month, 5 days refused = approximately €460.

Does this decision apply to private employers? Yes, the principle is general: every employer is responsible for applying employment law, regardless of the source of the incorrect instruction.

Can I take action against the UCANSS? No, the Court held that liability remains with the employer. You can only take action against your employer.
