This includes an hour nap in his car, lunch for 2 hours, and running errands/personal things outside the office for a few more hours.
If he sat down and worked straight, we figured he would only need to be in the office no more than 8 hours
(Now if he claims he works 14-hour days, that's a bit dishonest.)
Suddenly my work hours were an issue. They started hard enforcing a department-wide policy where if you weren't seen at your desk, you're assumed to be not working. Under the threat of being fired, I was forced to sit at work from 9am to 7pm. I suspect managers also had "monitors" assigned to keep a watch over employees like me and hours we were at our desks.
It was a massive waste of my time as I was now spending a additional 20 hours a week at the office to do the same amount of work as before.
