Imagine you are the owner of a real estate agency in Saint-Vincent-de-Tyrosse. You have negotiated additional leave with your employees through the collective agreement, thinking you were doing the right thing. But then one day, one of them claims a different remuneration for these rest days. Who is right? How to calculate these conventional leave days?
This situation, although drawn from employment law, indirectly affects all real estate professionals who employ staff. Because behind the walls of agencies, law firms or development companies, remuneration issues are at play that can generate costly disputes.
The Cour de cassation, in a 1997 ruling that remains relevant today, provides a clear answer: the protective rules of the French Labour Code also apply to additional leave. But what exactly does this change for you, as a property owner, tenant or professional in the sector?
The facts: a story as it happens every day
In this case, we are in 1993. Mr. Dupont, an employee of a company in the transport sector, benefits from a collective agreement that grants him six additional days of paid annual leave. These days are added to the statutory leave and are spread over three quarters outside the main holiday period.
The employer, a company based in an industrial region similar to that of Tarnos with its business zones, applies an internal practice to remunerate this additional leave: it pays salary maintenance, i.e., the normal salary, without applying the one-tenth rule provided for by the French Labour Code for paid leave.
Mr. Dupont challenges this practice. He believes that the one-tenth rule (which consists of calculating the paid leave allowance by taking 10% of the total remuneration lost during the reference period) is more favourable and must apply. The employer resists, arguing that since this leave is conventional, it can apply its own rules.
The dispute goes up to the industrial tribunal (specialised jurisdiction in employment law), then to the Court of Appeal. At each stage, positions clash. Finally, the Cour de cassation is seized. The judicial process will have lasted nearly four years, a typical timeframe for this type of litigation.
The court's reasoning — dissected
The judges of the Cour de cassation analysed the case with impeccable logic. They relied on Article L. 223-11 of the French Labour Code (which determines the method of calculating the paid leave allowance). This article provides for two methods: salary maintenance or the one-tenth rule, retaining the one most favourable to the employee.
The crucial point? The court qualified these provisions as being of public policy. In other words, they are binding on everyone and cannot be overridden by less favourable agreements. What few people know is that this notion of public policy protects the employee against provisions that would disadvantage them.
The court then extended this principle to additional leave of conventional origin. In short, even if this leave is not provided for by law but by a collective agreement, its remuneration must respect the protective rules of the French Labour Code. The employer cannot invoke an internal practice to impose less advantageous conditions.
In this case, the one-tenth rule proved more favourable. The court therefore confirmed that Mr. Dupont could claim the benefit of this calculation method. This decision represents a confirmation of the protective case law for employees, but it has the merit of clarifying a grey area: the application of legal rules to conventional benefits.
What this changes for you — concretely
If you are a landlord employing staff to manage your properties in Tarnos, this decision directly concerns you. You must check how you remunerate your employees' additional leave. For example, for an employee earning €2,000 gross monthly with additional leave, the calculation can vary by several hundred euros.
For a tenant, the impact is indirect but real: if your landlord employs a caretaker or maintenance agent, disputes over leave could affect the management of your building. undefined, I have come across cases where employment disputes delayed essential works in co-ownership.
Real estate professionals (agents, developers, surveyors) must pay particular attention to their collective agreements. How to react? First, conduct an audit of your practices for remunerating leave. Secondly, anticipate potential regularisations that could go back three years (limitation period for salary matters).
Be careful, however: this decision does not create new rights, but it reminds us of the strict application of existing rules. If you are in this situation, you must systematically compare the two calculation methods and retain the one most favourable to the employee.
Four tips to avoid this type of dispute
- Check your collective agreement: Precisely identify the additional leave provided for and their indicated remuneration method. Do not rely on internal practices.
- Systematically calculate both methods: For each employee, compare salary maintenance and the one-tenth rule. Document this calculation to prove your good faith in case of an inspection.
- Train your HR staff: Ensure that the people in charge of payroll know this legal obligation. A repeated calculation error over several years can generate significant arrears.
- Consult a specialised lawyer: Before changing your practices or responding to a claim, have your situation checked by a professional. A preventive consultation costs less than a lawsuit.
Deep dive: related case law and developments
This 1997 decision fits into a consistent line of case law. Already in 1985, the Cour de cassation had affirmed the public policy nature of the rules on paid leave (ruling No. 83-40.187). It has since regularly recalled this principle, notably in a 2015 ruling concerning the construction sector.
The trend of the courts is clear: maximum protection of the employee, with an extensive interpretation of favourable rules. Judges consider that conventional benefits must not be used to circumvent legal guarantees.
For the future, this case law remains solid. Reforms of employment law have not called these fundamental principles into question. However, the increasing complexity of collective agreements and the multiplication of special statuses make the verification of calculations more and more technical.
In practice: what to do
FAQ: Frequently asked questions
1. How to know if the one-tenth rule is more favourable?
Calculate: 1) Salary maintenance = normal salary during leave. 2) One-tenth rule = 10% of the total remuneration lost during the reference period. Compare the two amounts.
2. Does this rule apply to self-employed individuals?
No, only to employees bound by an employment contract. Self-employed real estate agents are not concerned.
3. What risks does an employer face if they do not comply with this rule?
Salary arrears for up to 3 years, late payment interest, and potentially damages for moral prejudice.
4. Can the collective agreement be modified to circumvent this rule?
No, any less favourable clause would be void as contrary to public policy.
5. How to check retroactively?
Keep the payslips for the last 3 years and recalculate with an accountant or lawyer.
