funny, here in Germany many offices and most homes don't have AC. Granted it's usually not that hot during the summer, but right now it has been around 85 since April and a lot of people are suffering at work, but nobody would quit because of that.
That’s the same as asking, “Who would seriously just switch jobs because of more money?”
It’s a quality of living thing. If you don’t loose anything but can gain something, why not do it?
I mean if your job only allowed you to sit on a small unpadded stool, wouldn't that motivate you to find a new job?
