I am not privy to the situation in SAS, so I don't know if the strike is justified or not but I have one thing to say to the colleages.
If you really believe this is the best solution to solve the problem for everyone, stand your ground!!
Sure, you may loose your job, but it is easier to work for another airline, and be able to look at oneself in the eyes when shaving in the morning, than to be ashamed not to have had the guts to do something.
Best of luck, guys and girls.
