Here's my not even semi-informed counter speculation based on what I've read about the UAW contract and from the tour of CAAP. The CAAP employees are on average much longer term (higher cost) than rank and file at Chrysler. The guys we talked to had been there for a long time, all 10+ yrs and one since CAAP opened. And to get hired on at CAAP, they had to prove themselves for years at other plants.
Based on new UAW contract, the auto makers can buy out expensive employees and hire new workers at substantially less cost over the long run.
So maybe the new mgmt is doing nothing more than trimming costs, as you would expect them to do, and it has nothing to do with the future of Viper except to make it a more viable/profitable product line for years to come.
Maybe I don't know squat (OK, that's true) and I'm completely wrong. But until proven otherwise I'll stick with the glass being half full.
