3151 hrs of overtime.

78.775 full-time 40 hour weeks there.

So assuming 2 weeks of vacation, he somehow managed to work 128.775 weeks in a year?

128.775/50 - let’s see how many work weeks he had to work each week to get there - 2.5755

So each week he had to be working about 2.6 normal weeks, or about 103 hours a week.

Assuming he worked 7 days each week, he was doing 14.7 hour shifts every day of those 50 weeks of working 7 days with no breaks.

Hmm.
