But getting in and out of an air conditioned vehicle can be very bad on a body. It would make more sense for them to get an early start and finish up earlier.
Nothing has changed in Arizona, summers are HOT.
A/C out here only works if the doors are closed, They hardly ever close their doors so it is pointless without a full body spacesuit. It’s not a cushy indoor job, it’s an outdoor job. Those like myself who have to work outside in Az carry lots of water and stay soaking wet, cloths and all. In a stiff breeze you can actually feel cold at times.
