Lindsey, it sounds like them man needs help really bad. If he's this angry at work and continues to hold onto this anger at home...then at one time or another, he's going to blow. You read in the paper all the time anymore about someone shooting up their place of employment.

I would seriously take copies of his MSN messages (if possible) and show the management. He sounds really scary to me and I would try my best to get him out of there.
