Being a UPS driver is hard work - and well compensated work at that. Ours at work makes well over $100K.
Maybe the wife should pack a cooler for her husband every morning so he doesn’t get heat stroke.
What kills you in the desert heat or in the heat and humidity of Houston when you are working, is not being able to respond to your internal thermostat, that is why you hear of people dying when they are doing an activity that is forced on them, like football practice or basic training.
On a good construction crew you monitor your men when heat is a problem, let them work at their own pace and if you see one overworking his body’s ability to cool him then you slow him down or pull him off for a bit.
The UPS drivers are working at a forced pace, a constant pace, and they need to be trained in some of the basic medical about heat problems and made to take a break if their body temp is climbing, an A/C blaster focused entirely on the driver would help them between stops and it would also serve for a cooling place to sit if they were forced to stop for a bit to let their internals settle down.
The problem that not everyone faces when working at their own pace is their internal thermostat getting out of control and they die.
“Being a UPS driver is hard work.”
Not really when compared to other professions like home construction or road work. I had to take a gig in the garbage business for 7 years. When I started I was 52 years old. The company was still hand loading old school trashcans. They didn’t have any automated trucks yet.
One truck with one driver on the routes. We drove to an address, jumped out of the truck, dumped 3 HEAVY cans, climbed back into the truck and drove to the next house to repeat the cycle. Every route was an average of 400 homes a day.
And this was in the desert southwest with no air-conditioning in 116 degree heat during the summer. Air conditioning was detrimental because the quick back and forth cool-hot temp changes would kill you.
The only way I could stay hydrated was to drink at least two gallons of water a day.
