seriously, tell her to grow up and snap out of the immature high school drama bullS***. Youve been there way longer than her, so why put up with her crap? You should have more authority than her, and the boss should trust you way more than her. With me, I give the respect I get. If someone wants to have attitude with me then the respect stops, and I can be just much a b*tch than them. With my last job I put up with one managers attitude thinking maybe he just is having a bad week, but when it continued and continued I left an hour early, got into a fight with him in the front of the restaurant - he started it and I finished it by quitting, he went back in the restaurant if he continued it I definatly would have started punching. I don't have any problem admitting that, no person has the right to be in my face about an issue I didn't start. But I think what would work for you for now, is the next time she tries to start something just smile and walk away. Don't say anything, ignoring those type people is usually best way to get them back. Really thats all their looking for, is attention.
