I have heard that it may help GM do something with future benefits. Somebody needs to stand up to the UAW and let them know that it's not unrealistic for the Big Three to take all production overseas.
For one thing, when GM spun Delphi off 6 years ago, the UAW forced GM to guarantee Delphi workers' pensions, etc. Now Delphi is in bankruptcy, and it's dragging down GM with it.
So GM is still feeding the Delphi workers even though they have not been part of GM for 6 years. And now it looks like the Delphi workers are going to strike, which will shut down all of GM in short order.
These union leaders are economic terrorists.
