What measures can I take in Texas if I am having several difficulties with my coworkers and management?

I don't know how high up the food chain you can go.

I don't know if Texas has anything equivalent to the Labor Relations Board. It's unlikely, if it does, that it works in really short time-spans.

Sometimes you have to live with a bad situation for a month.

You could go to the media, but that might put your future job in jeopardy.

You've already disallowed any of the usual things that can be done -- saying you can't trust anyone; that "Sally" has everyone in her pocket.

Try to make amends with Sally -- though you've probably already made it clear you loathe and despise her, so that wouldn't be easy.
