So you live in his apartment? and he is your employe? not sure if I'm getting that right. Then he could evict you and you could fire him? Big conflict of interest here.

At some point people have to learn the respect lesson the hard way. He could choose to do things differently. There is no reason why you need to sacrifice your health when he doesn't appreciate it. I'd give him the boot even if he would evict you - especially if you can afford to get your own place. You don't deserve the crap he's dishing out. He's being a bully. The other employees don't deserve that either.
