Here is a dilemma. I work alone, outside, in rural America. The heat index is well above 100° all summer. (sometimes 130°+ ) I spend most days in the sun doing physical work. My employer allows a fifteen minute break in the morning, another in the afternoon, and an unpaid hour for lunch. I must keep the truck locked with the windows up while I work. But I am not permitted to crank the work truck and run the air conditioner. Ever. They even installed electronic devices on all the company vehicles to record "idle time." So when break time rolls around, I can either rest in the sun, or rest in the hot truck. (I can have the windows down while I am in the truck.) If I were to fall victim to the heat, no one would know until knock off time.
