In this economy..and particularly their industry, I would have to say ANY job, even if it isn't that great, is better than NO job. Believe me, there aren't that many jobs out there, so I wouldn't throw it away unless I had something else lined up.
Hopefully, somehow, things will get worked out. There has got to be a way to get costs more soundly aligned and have a place where people would like to work (unions or not).
