Guys partying on the clock at Chrysler...

They'll get fired, grieve the firing with the UAW, get their jobs back after it goes through the grievance process, and get paid back pay for their time off.
New management since the bailout, and UAW will have their backs.
Can't prove anyone was drunk at the time now, nor can they prove they were high. The bottles were in bags, so a decent steward would point out that may just be pepsi. As for the pot, what pot? That was tobacco.
I see it happen all the time, there is a Ford plant not far from here and there is a bowling alley literally at the end of the parking lot. Go in around lunch time and there will be 50 or 60 plant guys there drinking lunch. There is usually 10 or 20 of them there at any other given time.
