Won't cross a picket line...oh, the horror. If the mechanics had any sense of reality you wouldn't be in the position of having to consider crossing a picket line. Regardless of any actions management may/may not have taken, the unions were going to have to make concessions to ensure the long-term survivability of the airline. IMO, the degree of concessions is not as important as the fact that they were going to have to be made...and the mechanics union wasn't going to make them.
