Strikes in Paris: how Americans can cope

A strike (une grève) in Paris is almost never a surprise: the law forces several days of notice, and you'll usually know the night before which trains are running.

The short version

Public transit strikes need notice. A union must file a strike notice at least five full days before a public-service strike starts [1].
Transit workers must declare 48 hours ahead whether they're striking, so operators can plan a reduced schedule [2].
"Minimum service" isn't a guarantee. The 2007 transit law organized notice and planning, but it didn't create a true obligation to run a minimum level of service [2].
Check the night before in the IDFM, RATP or SNCF apps, and have a plan B: bike, walk, work from home or leave very early.
Big national strike days can hit flights, schools and garbage pickup too, as Paris saw in 2023 [3].

Why Paris strikes so much (and why locals shrug)

Back home, a transit strike is front-page news because it's rare, and in many states public employees can't legally strike at all. In France the right to strike is part of the constitution, and transit, rail, teachers, air traffic controllers and garbage collectors all use it. The State Department's France page puts it plainly: peaceful demonstrations and strikes "occur regularly and can disrupt transportation" in Paris and across France [4].

The rhythm is predictable once you've lived through one. National unions call a "day of action" (journée de mobilisation), often against a reform like the pension changes of 2023. Strikes and a big afternoon march happen the same day. Sometimes a rolling strike (grève reconductible) follows, renewed day by day by worker votes.

Parisians grumble, adapt and mostly support the right to strike even when they don't love the strike. You'll do better if you treat it like a snow day in Chicago: annoying, survivable, and best handled with a plan.

How strikes are announced

The five-day notice

In public services, which include the RATP (metro, buses, most trams) and the SNCF (RER lines, suburban trains, intercity trains), French labor law requires a strike notice (préavis) from a representative union. It must reach management "five clear days" before the strike starts and state the reasons, the area covered, the start time and whether it's open-ended [1]. During that notice period, both sides are supposed to negotiate [1].

That's why you'll often read a headline like "préavis de grève déposé pour le 5 décembre" a week or more ahead. Some unions file long open-ended notices covering weeks or months, so a notice on its own doesn't mean anyone will actually walk out.

The 48-hour declaration

The real signal comes from a 2007 law on continuity of public transport, now part of the Transport Code. Each transit worker who plans to strike must tell the employer 48 hours in advance, so the operator can reorganize routes with non-striking staff [2]. Operators then publish a forecast traffic plan, typically by late afternoon the day before.

Here's what that looks like in practice:

When	What happens	What you do
A week or more out	Unions file a strike notice; national days of action are announced in the news [1]	Mark the date; warn your boss and your kid's school
48 hours out	Workers declare individually whether they'll strike [2]	Start thinking about plan B
Evening before	RATP and SNCF publish line-by-line forecasts	Check your lines in the apps and plan your route
Strike morning	Service runs as forecast, often thinner at rush hour	Leave early, or don't go

What "minimum service" really means

You'll hear "service minimum" a lot. It's a bit of a misnomer. The law organized advance notice, negotiation and priority routes, but, as French commentators point out, it did so "without setting up a real obligation of minimum service" [2]. Agreements between unions and transit authorities can set rush-hour priorities, but if most drivers on a line strike, that line can still shut down or run a train every half hour.

Automated lines tend to hold up better. Metro lines 1 and 14 run without drivers, so they're often the last lines standing on a heavy strike day. In March 2023, on the biggest day of the pension strikes, only two metro lines ran normally [3].

Where to check before you leave

Bookmark these and turn on notifications:

The Île-de-France Mobilités app: the regional transit authority's app, with traffic alerts for all operators and digital tickets.
The RATP's Bonjour RATP app and website: line-by-line forecasts for metro, bus, tram and the RATP-run parts of RER A and B.
SNCF Connect and the Transilien pages: forecasts for RER C, D and E, suburban lines, TGVs and intercity trains.
Your airline's app for flight cancellations when air traffic controllers or airport staff strike.
The US Embassy in Paris alerts via STEP: the embassy sends demonstration alerts to Americans enrolled in the Smart Traveler Enrollment Program.

French news sites and radio run live strike blogs on big days, and the hashtag of the day on social media is often more current than any official page. And our community group for Americans in France tends to light up the night before with "is the 9 running tomorrow?" questions.

A game plan for strike days

Read the forecast the night before. Look up your exact lines, not just "the metro." A line can run every third train, or only during rush hour.
Talk to your employer early. Many Paris offices allow remote work on big strike days. Ask now so you're not negotiating at 7 a.m.
Have a bike plan. Paris has added a lot of bike lanes in recent years, and Vélib' bikeshare stations fill up fast on strike mornings. Owning a bike, or even a scooter, pays for itself in one bad week.
Walk more than you think. Central Paris is compact: crossing from the Bastille to the Eiffel Tower is roughly 6 km (about 4 miles). Comfortable shoes are a strike-day essential.
Avoid the marches. Big demonstrations usually run in the afternoon between landmarks such as République, Bastille and Nation. Metro stations near the route may close. The State Department warns that demonstrations can turn violent and that police have used tear gas and water cannons [4].
Expect crowds on whatever does run. If only a couple of lines are working, they'll be packed. Travel off-peak if you can.
Rideshares and taxis get pricey and slow on strike days, since everyone has the same idea and traffic backs up.

Long-distance trains and flights

SNCF strikes often target holiday weekends. If your TGV is canceled, SNCF normally offers an exchange or refund; check your booking in SNCF Connect. Air traffic controller strikes can ground flights at Orly and CDG even when your airline isn't striking. In March 2023, authorities asked airlines to cancel a fifth of flights at Paris airports [3]. If you're flying home for Thanksgiving or Christmas, build in a buffer day.

Kids and schools

Teachers strike too, and public schools must tell parents ahead of time when a teacher will be out. Many towns run a minimum childcare service on strike days, but in practice that varies by school, so watch your child's school notebook or app and line up a backup sitter.

When the garbage piles up

Sanitation strikes are rarer but memorable. In March 2023, Paris garbage collectors struck for more than two weeks, trash piled up in the streets, and police eventually ordered a minimum service [3]. If it happens again, keep your trash inside as long as you can and hold off on that Costco-size shopping run.

Money and refunds

If you pay for a monthly or annual Navigo pass, a strike doesn't automatically get you money back. After some major strikes, IDFM has offered partial refunds to pass holders, but that's a case-by-case decision announced afterward, so watch the news and IDFM's site. For single tickets, there's nothing to claim. A Navigo Month pass cost EUR 90.80 (about USD 101) in 2026 [5]; USD conversions use the Federal Reserve H.10 rate of October 30, 2026 (EUR 1 = USD 1.1163).

For train tickets, use the SNCF's own exchange and refund options, and for flights, EU air passenger rules may entitle you to rebooking or a refund, though compensation rules have exceptions for extraordinary circumstances. Your airline will spell out your options.
