I really like to stay under the radar at work, because I had the crazy-office-lady latch onto me. I genuinely liked her, we had a lot in common, she made me laugh. She began to spread rumors about our co-workers making me complicit because she would always get caught talking about someone to ME. I began to distance myself from her outside of work, but maintained a friendly work camaraderie. She noticed my distance, turned against me, spread rumors about me, gave me the silent treatment at work and then got me WRITTEN UP for promoting a hostile work environment. I requested a promotion to get out of her department but we still worked in the same building. Pretty soon she found herself totally without friends at work, accused her supervisor of being prejudiced against her, and walked out on her job with no notice.

Wow, that was a really long thread hijack, I apologize. As I was alluding, if you make her too angry she can bring punitive action against you at work. If you don't want to report her for harassment you could try what was done to me. Her malicious rumors about your coworkers are promoting a hostile work environment. I would make triple sure I wrote down every occurrence, date, time, any witnesses, and the gist of the conversation. Once you have evidence take it to your supervisor or HR every single time. Having worked with her this long, they must know what she's like by now, and probably don't have just cause to discipline her.

This is tough, good luck to you!
