If you're on the same team and supposed to be working together why does a coworker say the most rude insanely mean spirited crap day after day?

The boss says she doesn't like a tattletale.

@FloorGenAdm: Sorry to hear that. But at least the boss is aware of the problem. So if anything else happens down the line. She knows full well what is going on. Maybe let HR know about the problem coworker.

@bhatjc: I'll keep that in mind, however the boss and HR are the same person.

@FloorGenAdm: Ah damn that sucks. Just keep plugging a long. Maybe the boss will get tired of the coworker
