Ask why there are so many strikes in France and you will get opinions. This guide gives you the rules instead: what makes a strike legal, why you read about one days before it starts, and the words a strike headline uses. We don't rank France against other countries here, because the figures depend on how you count. Every legal point below comes from official sources, checked October 2026.
Learners tell us, in these words, "I read the news, but not what's behind it." Strike stories are a good example. Préavis, reconductible, intersyndicale: each word stands for a rule or a habit that French readers know and nobody explains.
A Right Written Into the Constitution
The Preamble of the 1946 Constitution says it in one line: « Le droit de grève s'exerce dans le cadre des lois qui le réglementent. » The right to strike is exercised within the laws that regulate it. Today's Constitution, from 1958, refers back to that Preamble, so the line still applies (Conseil constitutionnel, checked October 2026).
It goes back further. A law of 25 May 1864 ended the offence of coalition, so that workers who stopped work together were no longer committing an offence (Légifrance, checked October 2026).
Service-public.gouv.fr defines a strike as « la cessation collective et concertée du travail en vue d'appuyer des revendications professionnelles ». In plain English, three things: people stop work together, they agreed to do it, and they are backing demands about their work. Pay, staffing and working conditions fit. In the public services, the same site adds, a purely political strike is not allowed.
The word itself comes from a place. Larousse traces grève to the Place de Grève in Paris, where workers without a job gathered to be hired.
Why You Read About a Strike Before It Happens
In the private sector, a strike can start at any moment and needs no notice (service-public.gouv.fr, checked October 2026). Many strike stories are about public services and transport, though, and there the rules make a strike visible days ahead.
The préavis
In the public services, a strike must be announced by a préavis, a formal notice filed by a representative union. It gives the reasons, the area covered, the start time and whether the duration is limited or unlimited. It must arrive at least five clear days before the strike, and both sides are expected to negotiate during that time.
A public agent does not have to stop work for the whole period the notice covers. That explains notices that run for weeks: they cover a period, and staff choose the days.
The 48-hour rule in transport
A 2007 law on regular land passenger transport, now in the Code des transports, requires the employees it covers to tell their employer at least 48 hours before they take part in a strike. With those declarations, the operator knows who will work, and stories about a transport strike often carry a traffic forecast before the day itself.
Teachers in nursery and primary schools also declare 48 hours ahead. When at least 25% of a school's teachers have declared, the commune (the town) organises a childcare service for the pupils.
So a single strike can reach you three or four times: the notice, the forecast, the day, and sometimes the decision to carry on.
One Day, or Renewed
A journée de mobilisation is a single day of action, often with marches in many towns. A grève reconductible is renewed, often day by day, until the strikers decide to stop. Larousse defines reconductible as something that can be renewed, which is why headlines say the strikers reconduisent le mouvement.
Some forms are not allowed in the public services, such as the grève tournante, where groups of staff stop work one after another. A grève perlée (working slowly) and a grève du zèle (applying every rule to the letter) are not strikes in the legal sense. Some public agents may not strike at all, including police officers, some prison staff, judicial magistrates and the military.
Grève or Manifestation?
The two words often share a headline, and they mean different things. A grève is stopping work. A manifestation, or manif, is a march or gathering on the public road (Larousse). A striker may march, and a march can take place on a Saturday with nobody on strike.
When several unions act together, the press calls the group l'intersyndicale, from the adjective Larousse defines as concerning several unions.
Three Strike Stories as They Ran in Better French
On 29 August 2026, a story about firefighters began:
« Une alliance de neuf syndicats de pompiers a déposé un préavis de grève du 8 septembre au 20 octobre. »
Tap un préavis de grève and Better French Context reads: « Mandatory warning before stopping work. » Then the note: « Notice must be filed 5 days ahead. » On the headline's Grève des pompiers, the note is the one from the Place de Grève: « Named after Place de Grève in Paris. »
Ten days later, on 8 September 2026, the strike itself:
« Les pompiers commencent ce mardi une grève de six semaines dans toute la France. »
The note on une grève: « Work stoppage to demand specific changes. » and « Striking is a constitutional right since 1946. » You can see the sequence from the section above: a notice in August, a strike in September, both covering the same weeks.
On 28 September 2026, the headline was about public servants:
« Grève des fonctionnaires : plus de 170 manifestations prévues ce mardi en France »
Here the strike and the marches share one headline. Tap plus de 170 manifestations: « Protest marches organized throughout the territory. » and « More than 170 gatherings were announced that day. » The same story said the SNCF and the RATP expected « un trafic presque normal », the traffic forecast in action. One of its Quiz Me questions comes with a "Did you know?" that explains a phrase found in many public pay stories: « French public sector base pay relies on a common multiplier known as the 'point d'indice'. »

Where Better French Helps
Every day, Better French picks fourteen stories from 40+ French sources and rewrites each one once in clear French, with the original one tap away. Strike stories come in with the rest, and we explain the words without taking a side. Tap préavis or reconductible and Better French Context gives the meaning and the cultural note, in English, French, German or Spanish.
Read in Your Language flips a story into English when you need it. Quiz Me asks three questions on what you read, with a short "Did you know?" about France along the way. VocaMatch helps you learn the vocabulary from what you read: the story's real words and expressions, at your level.
An honest limit: Better French will not tell you whether your train runs tomorrow. Check the operator for that. What it gives you is the background, so that the next strike headline reads as a sentence and not a puzzle.

Frequently Asked Questions
Why are there so many strikes in France?
We don't rank France against other countries, because the figures depend on how you count. The rules do explain why strikes are so visible: the right is in the Constitution, public service strikes are announced by a préavis, and transport workers declare 48 hours ahead, so a strike is reported before, during and after.
Is striking legal in France?
Yes. The Preamble of the 1946 Constitution says the right to strike is exercised within the laws that regulate it. A strike means stopping work together, as agreed, to back demands about work. Some public agents, such as police officers and the military, may not strike.
What is a préavis de grève?
A strike notice. In the public services, a representative union must file it at least five clear days before the strike, with the reasons, the area, the start time and the duration. In the private sector, a strike can generally start without notice.
What does grève reconductible mean?
A strike that is renewed, often day by day, instead of being set for a single date. Strikers decide whether to carry on, which is why a headline may say they reconduisent le mouvement.
What is the difference between a grève and a manifestation?
A grève means stopping work. A manifestation, or manif, is a march or gathering on the public road. They often happen on the same day, but either one can happen without the other.
