In France, working hours are at the heart of many professional relationships and constitute one of the main sources of disputes before the Conseil de prud'hommes (French labour tribunal). Whether you are a French employee or a foreign worker living in France, understanding how overtime (heures supplémentaires) works is essential to protect your rights and ensure you are fairly compensated for your work. Between applicable overtime pay rates, collective bargaining agreements, and the sometimes complex burden of proof, this comprehensive guide provides you with all the legal and practical keys to mastering the subject of overtime.

Before addressing how overtime is paid, it is necessary to precisely define what constitutes overtime. In French labour law, the statutory working week for a full-time employee is set at 35 hours per week (which equates to 151.67 hours per month).
Any hour of work performed beyond this statutory weekly limit, at the request of the employer or with their implicit agreement, is considered overtime.
Overtime is calculated within the same calendar week. Unless otherwise specified in a collective agreement, the calendar week begins on Monday at 0:00 AM and ends on Sunday at 12:00 PM (midnight).
However, there are maximum limits beyond which an employee cannot work, even with overtime:
Please note that not all employees are subject to the 35-hour week. Senior executives (cadres dirigeants) are excluded. Furthermore, many executives (and some autonomous non-executives) sign a convention de forfait en jours (flat-rate day agreement, often 218 days of work per year). For these employees, the concept of daily overtime does not exist, as their working time is counted in days or half-days. On the other hand, for employees on a flat-rate hourly agreement (forfait en heures), overtime hours are integrated and paid on a smoothed basis each month.

The principle is simple: every hour of overtime worked entitles the employee to an increased rate of pay or, under certain conditions, equivalent compensatory rest time.
According to Article L. 3121-33 of the Code du travail (French Labour Code), a company-level collective agreement or accord (or, failing that, an industry-wide branch agreement) can set the overtime pay rate. However, this rate can never be lower than 10%.
In the absence of an applicable collective agreement or company accord, the default statutory rates set by Article L. 3121-36 of the Code du travail apply:
The annual quota (contingent annuel) is the volume of overtime hours an employer can request an employee to work over the year without specific authorization. In the absence of a collective agreement, the regulatory quota is set at 220 hours per year per employee.
Any hours worked beyond this quota of 220 hours automatically trigger, in addition to the overtime pay rate, a mandatory compensatory rest period (contrepartie obligatoire en repos or COR) equal to:

To help you better understand the financial impact of overtime on your payslip, here are two calculated simulations.
Let’s take the case of Jean, an IT technician. His gross hourly rate is €15. He usually works 35 hours per week. During a high-activity week, Jean works 45 hours.
Here is the breakdown of his calculation for that week:
1. Normal hours: 35 hours paid at the normal rate of €15, which is €525.
2. Overtime hours paid at +25% (the first 8 hours, from the 36th to the 43rd hour): 8 hours x (€15 x 1.25) = 8 x €18.75 = €150.
3. Overtime hours paid at +50% (hours beyond the 43rd hour, i.e., the 44th and 45th hours): 2 hours x (€15 x 1.50) = 2 x €22.50 = €45.
For this 45-hour week, Jean will receive a total gross salary of €720 (€525 + €150 + €45) instead of his usual €525. His extra earnings from overtime amount to €195.
Let’s take the case of Maria, an administrative assistant in a company covered by a collective agreement that sets the overtime pay rate at the statutory minimum of 10% for all hours. Her gross hourly rate is €12. She works 40 hours in a week.
1. Normal hours: 35 hours paid at the normal rate of €12, which is €420.
2. Overtime hours paid at +10%: 5 hours (from the 36th to the 40th hour) x (€12 x 1.10) = 5 x €13.20 = €66.
For this week, Maria will receive a gross salary of €486. Thanks to the company agreement, the employer legally applies the minimum 10% rate instead of the default 25% provided by law.

This is the most crucial and conflict-prone point in French labour law. If you believe you have not been paid for your overtime hours, how do you prove it in court?
Contrary to popular belief, it is not solely up to the employee to prove that they worked overtime, nor is it solely up to the employer to prove the contrary. Article L. 3171-4 of the Code du travail establishes a shared burden of proof mechanism:
1. The employee must first present elements that are sufficiently precise to support their claim, allowing the employer to respond.
2. The employer must then provide the judge with elements justifying the hours actually worked by the employee (badge system records, timesheets, etc.).
The Cour de cassation (French Supreme Court) strictly ensures that lower court judges do not place the burden of proof solely on the employee. If the employee provides initial elements of proof, the employer cannot simply deny the claim; they must provide their own records.

If you notice that your overtime hours are unpaid or undervalued, here is the recommended procedure to assert your rights.
Do not wait for a conflict to arise to gather your evidence. Keep a daily record of your hours. The following items are accepted by courts as "precise elements":
Schedule a meeting with your Human Resources department or your employer. Calmly present your summary of hours. Sometimes, it is simply an entry error or an administrative oversight.
If verbal discussions fail, send a formal letter of demand via lettre recommandée avec accusé de réception (registered mail with acknowledgement of receipt, or LRAR) to your employer. In this letter, formally claim the payment of your overtime hours, attaching your detailed breakdown. Set a reasonable deadline for a response (for example, 15 days).
If the employer refuses to pay or does not respond, you must file a claim with the Conseil de prud'hommes. You can do this on your own or be assisted by an employment lawyer or a union representative (défenseur syndical). The court will analyze the documents provided by both parties to make its decision.

To act effectively, you must keep in mind the time limits and financial rules set by French law:
---
---
Yes, performing overtime decided by the employer is mandatory for the employee within the limits of the annual quota. A systematic refusal without a legitimate reason (such as compelling family obligations or non-compliance with mandatory rest times) can constitute professional misconduct that may lead to dismissal.
Yes. A company or branch collective agreement can provide for the replacement of overtime pay (and the corresponding increase) with equivalent compensatory rest (known as repos compensateur de remplacement). For example, an overtime hour with a 25% increase can be compensated by 1 hour and 15 minutes of rest.
If your employer intentionally fails to mention your overtime hours on your payslip and fails to pay the corresponding social security contributions, they commit the offense of concealed work (travail dissimulé, Article L. 8221-5 of the Code du travail). Upon termination of your employment contract, you can claim a flat-rate indemnity equal to 6 months' salary before the Conseil de prud'hommes.
Absolutely. French labour law applies in the same way to all employees working on French territory, regardless of their nationality or the regularity of their administrative status. You are entitled to the same pay rates and the same rules of proof as French employees.
