Therein lies the hang-up, the UAW owns a sizable chunk of GM stock and doubtful they'll be ousted.
Survival sometimes demands sacrifice. There’s no law that says the UAW must exist. It used to be that a kid in the Midwest didn’t have to have a college degree to make a decent living. The UAW has killed that. The old guys in the UAW got what they wanted, but their Grandkid’s friends can’t make a decent living.
