When I was an operating systems developer for Sperry Univac in the early 1980 (writing in assembly - go Telcon!) the company instituted mandatory 10 hour days. That pissed people off enough that we decide to only work 10 hour days. I was working probably 70 hours a week at the time and dropped to the required 50 (8am to 6pm M-F and managers did a head count at that time).

We didn't get overtime. When I went to work for Boeing in 1984, I was surprised to find that they had to pay overtime due to the federal rules for military contractors.
