I am in Texas working in a retail store and the AC has been out 12 days now. It has been over 100 degrees all of those days and is usually around 95 in here. The AC guys came for the first time today and said the whole system has to be replaced and it will take 10 days to do. I am being told by people in the company that they are totally within the law and there is no potential legal or lawsuit liability or anything. I am hearing something very different from customers, some of which are business owners and such. We only have 3 employees at any given time, and one quit because of the heat. So the two of us have been working 12 hours shifts, and we're not allowed to leave to get food or water, and the company isn't paying for drinking water. The other employee had to take a day off from work because they had heat exhaustion. My gf has noticed that I seem confused and dizzy and that I seem to have heat exhaustion when I get home, and I've almost fainted or thrown up at work. Is this really legal? Is this a thing?
