Strikes in Spain: Notice Rules and Minimum Services in Barcelona
How strike notice works, who decides how many trains and buses run, what designated workers must do and where to check service before you travel.

Strikes in Spain must be announced at least five calendar days in advance, or ten days when they affect a public service such as transport, health or schools. For those services the government sets servicios mínimos (minimum services): in Barcelona the Generalitat fixes them for the Metro, buses, Rodalies and public schools, and the Spanish Ministry of Transport for long-distance trains and airports. Workers named to cover them must work.
Who can strike and how much notice is needed?
The right to strike is in Article 28 of the Spanish Constitution. The procedure still comes from a 1977 law, Real Decreto-ley 17/1977 on labor relations, as interpreted by the courts:
- A strike can be called by workers’ representatives, unions or the workers themselves by vote.
- The employer must be notified in writing at least five calendar days before it starts.
- When the strike affects companies providing public services, the notice is ten calendar days, to both the employer and the labor authority, and the strikers must publicize it so users know.
- The notice must state the aims, the steps taken to resolve the dispute, the start date and the strike committee.
That ten-day rule is why strikes on the Metro, Rodalies or at El Prat are usually announced more than a week ahead, which gives you time to plan. Employees’ rights during a strike, including pay and protection from replacement, are covered in our guide to employee rights in Spain.
Who sets minimum services in Barcelona?
For public services and those of “recognized and urgent need”, the 1977 law lets the government authority set the measures needed to keep them running. Which government decides depends on who is responsible for the service:
| Service | Who usually sets minimum services | Where they are published |
|---|---|---|
| Metro and TMB buses | Generalitat de Catalunya | TMB website and app, Generalitat announcements |
| Rodalies regional trains | Generalitat de Catalunya | Rodalies and Renfe websites |
| High-speed and long-distance trains (AVE, Avlo and others) | Spanish Ministry of Transport | Operator websites, ministry announcements |
| El Prat airport and air traffic | Spanish Ministry of Transport | Aena, airlines, ministry announcements |
| Public schools and public health centers | Generalitat de Catalunya | Department notices and the DOGC, Catalonia’s official gazette |
Minimum services are usually expressed as a percentage of normal service, often higher at rush hour. In recent Rodalies strikes the Generalitat set around two thirds of trains at peak times and one third the rest of the day, but every order is set for that specific strike. Unions can and do challenge them in court.
Do workers have to cover minimum services?
Yes. Workers whom the company designates to maintain the minimum services must work during the strike. The 1977 law treats refusing as a fair cause for dismissal, on top of other liability. Everyone else on strike does not get paid for the strike hours and cannot be replaced by outside workers hired for the purpose.
Workers who choose not to strike can keep working. The employer cannot force them to strike, and strikers cannot stop them from working.
How do you check services on a strike day?
- Look for the official minimum services order a few days before. The Generalitat publishes its resolutions, and operators repeat the percentages on their sites.
- On the day, check the operator’s live service page: TMB for Metro and buses, Rodalies for regional trains, Renfe or the private operator for long-distance trains, and your airline for flights.
- Expect the protected percentage at rush hour, not a full timetable. Trains that do run tend to be crowded.
- For El Prat, cancellations are announced by the airline. Ask it directly about rebooking.
- For schools, the school informs families about the minimum staff and whether classes run.
See our Rodalies guide for the regional lines and how service updates work.
Can you get a refund?
It depends on the ticket and the operator. For train tickets, operators often announce free changes or cancellations for strike days, with conditions set in each announcement. For flights cancelled because of a strike, EU air passenger rules give you the right to a refund or rerouting; whether compensation is also due depends on whose staff went on strike. Check the operator’s notice for that strike before you buy a new ticket.
What about general strikes?
A general strike (vaga general in Catalan, huelga general in Spanish) is called by unions across sectors on the same day. Minimum services are then set for each public service, so the Metro, buses and trains run at reduced levels while shops and offices may close.
Bottom line
When a strike is announced, look up the minimum service percentage for your line and plan around rush hour, when protection is highest. For flights and long-distance trains, change your booking early, because seats on running services fill quickly once a strike is confirmed.
FAQ
Can a strike be called with no notice?
The law requires five days’ notice, or ten for public services. A strike called without notice can be declared unlawful.
Are minimum services the same for every strike?
No. Each order is set for a specific strike, depending on the service, the dates and the duration.
Can I be fired for going on strike?
No, a lawful strike suspends the contract but does not end it. The exception is a worker who refuses to cover assigned minimum services.
Where can I read the full strike law?
Royal Decree-law 17/1977 is on the BOE website, with later court rulings shaping how it applies.
