ADVERTISEMENTStrikes are a regular occurrence in Europe, as employees withhold their labour to fight for better pay and conditions.
Walkouts are sometimes planned months ahead but others are announced last minute, showing that it always pays to check before you travel.
Luckily, we have gathered all of the strike information together below.
Read on to find out where and when are walkouts taking place.
If your flight or train is cancelled or delayed, you will be entitled to a new ticket or compensation. Read our guide for the full details.
France: Flights cancelled from Paris and Marseille
France’s civil aviation authority has told airlines to cancel flights at airports in Paris and Marseille on Friday 13 October, as part of a broader union push for wage increases.
Around 40 per cent of flights in and out of Paris Orly will be cancelled, 25 per cent in and out of Marseille-Provence airport and 15 per cent in and out of Paris Beauvais.
Airlines tend to protect long-haul flights in these situations, so short-haul journeys are more likely to take the hit. But anyone with a trip booked between 12 October evening and 14 October morning is advised to check with their airline.
Cancellations are also likely on the railways and Metro on Friday, as the relevant unions have voiced their support for the strike.
A full strike timetable is expected from SNCF and Paris public transport network by Thursday afternoon to help people plan.
