I only know his history in broad strokes. He has a "reputation," I just don't know the specifics. He hated the guy that I replaced - 3 months later and he is still publicly bad mouthing the guy. Very unprofessional, makes for a hostile work environment.

Is taking him out for a beer an option? I'd recommend nipping this kind of thing in the bud as quickly as possible; or it'll just spiral out of control.

If you can: be diplomatic, take him out for drinks after work one day and have a heart-to-heart. He wields a significant amount of power, and it'd be in your best interest for him to like you alot.

i'm not sure if that would work with him, but i will give it some consideration.

"How he talks about his ex-girlfriend is how he will talk about you."

Word substitute accordingly. There's a reason it's a bad idea for candidates to bad-mouth their current employer, and it's the reverse of this situation.

So true. Best to stay clear of those kinds of people.

A general policy of mine is to avoid people who are frequently bad-mouthing other people. I think this is your key indicator of his character, and yes it does make for a hostile, and corrosive, work environment.

i am quickly adopting it as my general policy, too. i'm tired of the insecurity, neediness, and negativity that accompanies that mentality (along with the things you mentioned).

I regularly bad mouth people, but in an equal opportunity humorous way. Myself included.

Do what you like. Are you aware of the impression you give ofyourself when you badmouth others?
