Mapshift - I agree with you, why jump into another man's dispute? No-one would, or I think does, unless they themselves have a desperate need to work. If a job is vacated by a disgruntled employee then it's going to be eyed up by the hungry unemployed..
Strikes unfortunately don't turn lousy employers into good ones - it just makes them look for the next chance to get their own back.
It is very sad when just one group of workers ignore the other groups within the same company and decide to bring it to it's knees. Who fights for all the other employees who are not so disgruntled and want to stay working? (and I am not suggesting the scabs do)
