My speculation had to do with believing that most IT employees, given this situation, would "work", at job related tasks, for over 40 hours anyway.
Personally, if a job that paid me for 40 hours a week expected me to work 60 for more then perhaps once or twice a year, I would quit instantly, so I've never understood the "mandatory 60-hour" meme.
Perhaps this is where our wires were crossing.
