When I worked, I seldom worked 8 hours a day. I was a legal secretary. If the boss was in trial, it was not unusual to work more than 12 hours a day. Weekends too. The few times I did leave at 5:30 (my supposed quitting time), people would joke that I was leaving early.
Most of the young people I know would never work so much. They think I must have been nuts to work like that. Of course, for the most part, my generation didn’t have the labor saving devices and the concept of working from home was just beginning to catch on toward the end of my career. But the work ethic my generation and previous generations had just isn’t there today.
I am a legal secretary and I still work hours like that.
