I never heard anyone getting sick from the temps. I'd rather have it warm than cold!
What you should do: Call off and use sick days. Or tell them you want to get trained in pfresh.
I have been heat sick, it isn't pretty and its dangerous.
You can't use sick days for the entire summer.. And you don't have a pfresh work at if you don't have the rest of the store working..
ThebeastPMT, better than having your check lane people puking cause they are starting to suffer heat stroke and people passing out in the back cause its close to a 100F inside the building.
