I used to work with UAW in the 90s and it was excruciating. I'd be on the floor with one of our machines and I wasn't allowed to even take a panel off with a screwdriver. There was one guy whose job allowed him to unscrew the panel and he was somewhere else, or on a smoke break. I spent so much time sitting around twiddling my thumbs, waiting for this or that person. It was the opposite of having a productive day, I'd never want to work like that.
