I used to date a girl some years back and her father worked for GM and was a UAW member. He had been with them for close to 20 years and,No joke, he made almost $80 an hour and guess what his job was..He covered for people on their breaks and lunches and the rest of the time..he and others that did his “job” slept in the break room. He told me himself he only really worked about 3-4 hours a day, the rest of the time he watched TV or slept.
I was talking with a guy at a gov’t site with union construction guys (gov’t employees). He was at a meeting and the boss was pleading with them to “just give me 4 hours of work a day and we can get back on schedule”. He had to plead though - anything more would be harassment.
Oh - they “work” 10-hour days with Friday-Sunday off.
