I'm sorry your having so much bad luck with this.

I'm female and I still have this problem. Not to be sexist or anything but females are more likely to start drama in a work place for no reason.
Two of my female co-workers are trying to get each other fired right now.
The only way to get past this is stay at the place longer than the evil rude girls who will eventually quit. Then try and make friends as fast as possible with any new people that are hired.

When I was first hired at the place I work. Like a legal insurance company my co-workers harrassed me all the time. Even the one that would hang out with me after work would be talking horrible things behind my back when I would come to our section. But I've been her over two years and two of the women quit and the new hires have a little more respect for me. I still have the problem with the women harrassing me some times too, but can't say anything about it because they are friends with my female boss. -_-

Just try and be positive and relize women are trying to make friends with as many people as possible in the work place because most of there drama is popularty fighting. So befriend them and listen to all the trash the talk.......... *sigh*...

Good luck, just know when applying for jobs. Past employers are not allowed to say why you where fired so that is a + for you.
