While thankfully that hasn't occurred, today GM announced workforce cuts of around 15% of workers, the closing of five plants, and that the Chevy Cruze, Chevy Impala, Chevy Volt, Buick Lacrosse, and Cadillac CT6 will no longer be produced.
The question, really, is whether this is the UAW tax or something else. In this case, GM asked for 8000 workers to accept buyouts, but only 2250 did. Going way out on a limb, I'm guessing that the huge pension cuts for salaried workers in 2009-2010 made them unwilling to take a buyout that might be snatched from them--and that has everything to do with Obama's UAW bailout, which maintained pay scales that cost GM $25 more per hour than Toyota and Honda pay in our country.
Others might point out that this also has a lot to do with the fact that GM doesn't really have anything to compete with Honda or Toyota sedans, or frankly with Mercedes, BMW, Audi, and Lexus luxury vehicles, and while I'd agree, I'd also point out that engineers worried about being laid off, and who have seen former colleagues get
Sad to say--and I write this as the owner of two GM vehicles and the son-in-law of a UAW retiree--I don't foresee good things for them in the future unless this changes in a major way.
