Yes, they came to me for "work related" injuries if we can use that term loosely. But they were the only group of people that didn't use their own time for this. Most people would come before or after work. They would also use the shower/sauna facility and take their time getting dressed before heading back.
As far as vacation time, my MIL works for UAW. She does not work at a plant and gets those 2 weeks off like everyone else paid. This is in addition to a generous vacation schedule. In comparison, my college educated DH who works in IT has 3 weeks off paid, and will not get more no matter what his seniority. MIL has 5 or 6 weeks off total.
I just came back from Michigan today. I have family that still lives there, work in the industry and I lived just south of there 93-05. I worked with my patients in 04 when everyone was upset because they would have to pay a portion of their own benefits and a co-pay for Dr. visits (under a new contract). This concept is not new to anyone else, but the auto workers thought it was unreasonable to participate in the health care costs.
As far as hiring out of high school, I know it's harder now than before. In the 90s I know several families that got their kids into Chrysler making 60k+ out of HS. I know there are plenty of college educated people working in the auto industry. They should not have as much trouble finding new employment if needed, compared to the ones who thought the industry would always be there for them. We have many friends in their 40s looking at a career change without any other skills and no way of making this kind of income as a line worker somewhere else.
