One who makes a point of always letting people know that he is now part owner of the company. One that makes a point of telling people that he doesn't ever raise his voice. One that dissects everything in life to either find a problem or find out how he can personally benefit from something?

Ya, I work for that asshole. My only bosses (2 of them) are the owners. I run the rest of the show and NEVER have a problem with anyone else. If there is a problem, I work on finding a solution instead of wasting time bitching.

How do I deal with this fucking asshole aside from shooting him?

I vote you blow him and your business up.

Give him pinworms.

ooh.. that's better.
just dont walk where he poops.

Hahahahahaha...where do I get them?
