Union tradesman here, heavy industrial. The most I ever pulled in one week was 102 hours. It was for a time sensitive, round the clock, “once we start this we can’t stop until it’s done” kind of affair. Imagine two 12 hour shifts, but when you’d normally leave, you’d stay as long as you could to help get the night shift guys up and running.

It only lasted the one week, and we all made an obscene amount of money, but any longer than that and I would have had to tell them I had to go back to my usual 60 hours. I had to force myself to stay sharp because there was dangerous shit that needed to be done, I couldn’t imagine 4 weeks of it. No one should be forced into it, even commuting home after work like that is dangerous.
