I was not speaking about Amazon in particular. We have labor laws for a reason unless you never studied such a subject in school and have no idea of what working conditions were like in the 19th and early 20th centuries.
If Amazon is forcing people to work without air conditioning, they should be held accountable. It’s as simple as that.
A lot of people work without air conditioning; construction workers, road pavers, roofers, in steel mills…etc.
No one to my knowledge is forcing anyone to work for Amazon. If they don’t like the working conditions, they are free to find work elsewhere.
