There was a time back in the day when I worked for this retail store.
They were not open 24/7 like some big stores, but we actually worked there overnight.
They would lock us in the store so we were not permitted to go anywhere, otherwise the alarm would sound and the police would show up. You had to bring your own lunch and snacks, otherwise you would starve. They at least brewed coffee though and had vending machines. I thought the temperature control settings were alright, but there were a few times when the HVAC system broke down. I guessed that they were not getting regular maintenance from the HVAC professionals. I don’t know a whole lot about commercial HVAC systems, but I know they need to be maintained just like any other HVAC system around. When we had issues with the HVAC, I also noticed the air quality wasn’t so great. Sometimes I would start to feel sick and I wished that we could open some windows or something, but no, I felt like I was locked in a cage when I would work through the night. Eventually, I brought my own air purifier and everybody thought I was nuts, but it actually did help me feel better. Of course, I quit working that job a long time ago. As a matter of fact, that particular retail store isn’t even in business any longer these days, all the locations have closed down for good. I have to wonder how many other businesses are going to shut down, seeing as a ton of businesses had no choice but to close during the pandemic.
