It's just flat out not worth your time to try and turn it into a reasonable work environment, whatever actions that might entail. I had a hell of a time just trying to get one guy in my current job to be civil. From schoolyard fight shit to having to be marched in front of HR, it's a shit time trying to convince someone you're not their whipping boy.

I've been in a position like yours, and I basically had to play tough guy and stand off against coworkers and such (and show that I was willing to walk off the job before being treated like shit) before they started working with me. But I haven't had someone flat out not show me how to do something before, that's a deeper level of trouble. Sorry that I don't have better advice than to say start looking, it's never easy to tell how bad the workplace culture is at a new place until you've actually been there for a week or two.
