Strike Rules for Employers in France: Pay, Notice and Rights
When your employees go on strike, or join a national day of action, you need to know what you can and cannot do. French strike law protects the right to strike strongly, and some instinctive employer reactions, such as hiring temps or noting the strike on a payslip, are illegal. This explainer covers notice, pay, payslips, replacement staff and the difference between strikers and staff blocked by transport strikes.
Key takeaways
- In the private sector, employees generally do not need to give advance notice before striking; public services require a 5-day union notice.
- You may withhold pay in proportion to the time on strike, but the payslip must not mention the strike.
- You must not replace strikers with fixed-term (CDD) or temporary agency workers; you may ask non-striking permanent staff to work overtime.
- Staff who cannot reach work because of transport strikes are not on strike: treat them differently.
As of late October 2026, strikes are a live issue for many employers in France. After a nationwide day of action against the cost of living on 17 October 2026, five unions (CFDT, CGT, FO, Unsa and FSU) called a national day of strikes and demonstrations on 5 November 2026. A public sector strike against planned spending cuts has also been running, and yellow vest groups have announced actions on 24 and 31 October.
A national strike call means some of your employees may stop work for a few hours or a full day, even if they have no complaint against you personally. In France, joining a national strike over general economic and social demands can be a lawful strike. Knowing the rules helps you stay compliant, keep the business running and protect working relationships. This article is general information, not legal advice. Check your collective agreement, the Code du travail and service-public.fr, and talk to an employment lawyer for specific cases.
What counts as a strike in France
In French law, a strike is a collective and coordinated stoppage of work to support professional demands that the employer knows about. A few points follow from that definition:
- It must be a full stoppage. Slowing down work or doing it badly on purpose ("go slow") is not a lawful strike.
- It is usually collective. In general, at least two employees must stop work together. A single employee can join a national strike call, though, which matters for small businesses.
- It must support professional demands. Wages, working conditions, jobs and broader social and economic issues such as purchasing power can qualify. Purely political demands with no link to work are more doubtful.
The right to strike belongs to each employee. A union calls a strike, but each person decides whether to join it, and nobody has to be a union member to take part.
Notice rules: private sector vs public services
This is where many foreign employers get caught out. French rules differ sharply between private businesses and public services.
| Sector | Advance notice | Notes |
|---|---|---|
| Private sector (most businesses) | Generally none required | Employees can stop work as soon as the employer knows of their demands |
| Some transport services | 48-hour individual notice | Prior negotiation rules also apply |
| Public services | 5-day union notice | Applies to public bodies and private companies running a public service |
In practice, for a typical shop, agency, workshop or office in the private sector, you may learn on the morning of a strike day who is stopping work. You can ask employees to tell you so you can organize the day, but in general you cannot require advance notice or punish someone for not giving it, unless a specific rule such as the transport rules applies.
Pay and payslips
A strike suspends the employment contract for the time on strike. The employee does not work, and you do not have to pay for that time.
Proportional deduction
You may withhold pay in proportion to the time on strike. If someone strikes for half a day, deduct half a day, calculated according to the usual method for unpaid absence under your payroll rules and collective agreement. Deducting more than the time actually lost, as a form of penalty, is not allowed.
The payslip must stay neutral
The payslip must not mention the strike. Use a neutral line such as "unpaid absence" for the deduction. Keep strike records separately and confidentially, and do not include them in performance files.
No penalties and no discrimination
Penalizing employees for lawfully striking is prohibited. That includes disciplinary action, withholding bonuses only from strikers in a way that targets the strike, worse assignments or blocked promotions. Bonuses that depend on actual attendance can be reduced for any absence, but they must treat all absences the same way.
Common mistake
Writing "strike" or "grève" on the payslip because it seems more transparent. It is not allowed. Use a neutral "unpaid absence" line, and make sure your payroll provider or software is set up that way before the next strike day.
Keeping the business running: what you can and cannot do
You are allowed to try to keep operating during a strike, but within strict limits.
No temps or fixed-term contracts to replace strikers
Employers must not replace strikers with fixed-term (CDD) workers or temporary agency workers. This is set out in Code du travail articles L1242-6 and L1251-10. Breaking the rule can bring a fine of €3,750, rising to €7,500 for a repeat offense.
Overtime for non-striking permanent staff
You may ask non-striking permanent employees to work overtime or to cover tasks normally done by strikers, within the usual rules on working time, rest and overtime pay. You can also reorganize work, adjust opening hours or postpone non-urgent tasks.
Other options
You can use subcontractors in some situations, but this is a sensitive area and should not be a disguised way of replacing strikers with temporary labor. Get advice before arranging outside help specifically for a strike day.
Staff blocked by transport strikes are not strikers
On national strike days, public transport is often disrupted. Many of your employees may want to work but cannot get there. They are not on strike, and you must not treat them as strikers.
Discuss practical solutions with them:
- Remote work where the job allows it.
- Flexible hours, such as starting later or finishing earlier, or making up time on another day.
- Leave or time off, by agreement.
- Car sharing or other transport arrangements among colleagues.
Pay rules depend on the situation and on collective agreements. If an employee works remotely or makes up hours, they are paid normally. If they simply cannot work and no alternative is possible, check your collective agreement and get advice before deciding on pay. Being consistent and transparent with everyone avoids disputes.
Hypothetical example
Imagine a small bakery chain with 20 employees in a large city. On a national strike day, four employees join the strike, six cannot travel because trains are disrupted and the rest come in. The manager, Thomas, reorganizes shifts, asks two full-time bakers to work two extra hours each as paid overtime and shortens opening hours at one shop. The six blocked employees agree to make up their hours over the next two weeks. Strikers' pay is reduced for the hours missed, shown as "unpaid absence" on the payslip. No temps are hired. The business and names are made up.
A strike-day plan for employers
- Watch announcements. Track union calls and announced dates, and note which may affect your staff or transport.
- Check your collective agreement. Look for rules on pay deductions, attendance bonuses, overtime and transport disruption.
- Plan minimum operations. Decide which tasks must continue, who among permanent staff can cover them and which tasks can wait.
- Communicate neutrally. Tell staff how you will organize the day, ask them to let you know if they will be absent so you can plan, and remind them of remote work and flexible hours options.
- Record absences accurately. Distinguish strikers from staff blocked by transport or working remotely.
- Process payroll correctly. Apply proportional deductions only for strike time, with a neutral payslip line.
- Look after safety. If demonstrations take place near your premises, apply your safety plan, such as adjusted hours or remote work.
Pro tip
Brief every manager on these rules before a strike day. Many problems come from well-meaning supervisors who call a temp agency, make an offhand comment about strikers or mark the wrong absence code. A short checklist for managers prevents costly mistakes.

Frequently asked questions
Can I ask employees in advance whether they will strike?
You can ask them to tell you so you can organize the work, but in the private sector you generally cannot require them to answer or punish them if they do not. In some transport services, a 48-hour individual notice rule applies.
Can an employee join a national strike even if there is no dispute in my company?
Generally yes. Employees can join a national strike call on professional, economic or social demands, such as wages or purchasing power, even if they have no specific demand against you. The usual rules on pay and non-discrimination apply.
Can I dismiss an employee for striking?
No. Dismissing or disciplining an employee for lawfully striking is prohibited. Only serious misconduct during the strike, assessed on its own facts, could justify action, and that is a matter for legal advice.
Do these rules apply in the UK or US?
No. Strike law is very different in the UK and US, with rules on ballots, notice and replacement workers that do not match French law. If you employ staff in several countries, apply each country's rules separately.

The bottom line
French strike law gives employees strong protection. In the private sector they usually need no notice, you can deduct only the time actually lost, the payslip must stay neutral and you cannot bring in temps or fixed-term workers to replace them. You can still keep running with overtime by permanent staff, reorganized work and flexible arrangements for people blocked by transport strikes.
Brief your managers, check your collective agreement and set up payroll correctly before the next strike day. When in doubt, check service-public.fr and ask an employment lawyer.
