For the spouse with the little children: MY SO has spent 40 years in the auto industry at two different OEMs. our family has been through at least a half dozen RIFs -- some deeper than this one. We have been on both sides of the RIF. My advice to those of you with small kids is this. In every crisis there are the adult issues and the kid issues. Sometimes they are not the same.
You are totally justified in being stressed and worried for your future and for the toll this is taking on your spouse. Sometimes this translates into the oddest worries in you kids. One RIF, our son somehow got worried that he wasn't going to get to go to kindergarten (of all things!) We wen t to K-mart about bought him a backpack and assured him that come September he would be in kindergarten. Another time our daughter was worried that we wouldn't get to spend a week up North. (the vacation was already paid for so I could assure her that come what may the camping week was going to happen.
This is REALLY tough for you and your family --you are TOUGHER. I have been there. During past RIFs, I would dig deep and say to my spouse (and myself) "We had a life before GM and I will be there to have that life with you after GM." I am am very blessed to be able to say that we do.
Good luck!
