Strikes are not fare. Majority of people have jobs where they cannot hold people as hostages. This gives those who are in such position and unfair advantages over everybody else as they can negotiate with the employer pay and conditions above what the market would give them.
Next time a pilot goes on strike why not go and look into the eyes of the families (many with children) at check-in who just realised that their only holidays are cancelled?
Would the striking pilots dare to explain to the children whose holidays they destroyed that this year they don't have the holiday they were looking forward for several month? Somehow I supposed they would prefer to leave these to check-in staff...
