The person who really hates working at their job and
treats all their fellow employees
like crap. They usually start lots of fight, yell a lot, and never ever
smile or have anything good to say.
Husband: I hate my new job.
Wife: Whats wrong?
Husband: Well they put me working with Jim and he's my department's
work jerk. He hates everything and he hates me for no reason. I mean I just started!
