Strikes 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.
