I ran outside crews for 20 years in the FL heat. IMO - that's about as hard as it gets. As others have said though - UPS drivers don't get to work at their own pace. They don't go home until their packages are delivered. You dick around, you go home late - and not on the clock or overtime. On you. It's a very tough job here in FL. I imagine it isn't a picnic in Thief River Falls in the winter either.
“UPS drivers don’t get to work at their own pace.”
Did you happen to read the rest of my post? 400 addresses, three heavy trash cans per stop, and they all had to be done in a twelve hour shift because as commercial drivers we were still regulated by hours of service laws.
We I started that job I couldn’t even drive the 30 miles home after work for the first two weeks. Had to grab something from the C-store across the street for sustenance and die in my car for the night.
