Oh, I just remembered something I think I should add. If you've already been doing this, wonderful, but if someone else is reading this and is being harassed, I wanted to stress the point to you that you should document everything! Like, seriously, bring a notepad and write down anything that can make your case if you have to go to your manager or HR!
At my previous job right before I took my current job, our unit secretary started nursing school, and a few months after that, she got too big for her britches, developed a rude, holier-than-thou attitude, and started condescendingly "suggesting" to very experienced nurses (like, they've been nurses 15+ years) how to do their job. Yeah, I'm not kidding.
I left before it got too bad, but my friends on the unit kept me in the loop because they wanted me to go to HR with them to report everything I had to deal with before I left. My friends filed a hostile work environment claim. The secretary found out about their claim and immediately filed a sexual harassment claim against them. Why? Well, in her mind, if they were filing a claim against her and trying to get her fired, it was most likely because they didn't like her because she was gay. Her behavior had nothing to do with her being gay. No, they didn't like her because she was a crazy, mean b*tch!
Anyway, her claim fell through because she didn't have any documentation that anyone was sexually harassing her (which makes sense, because no one was harassing her!). Unfortunately, my friends who had good reason to report her lousy behavior never thought to write every rude thing down that she did or said, and since they had nothing in writing, the unit secretary was allowed to come back and work after stretch of administrative leave. My friend told me it made for a very awkward work environment until the secretary transferred to another unit some months later.
HR told the unit that they could see right through the secretary and felt something was off about her, and she definitely would have definitely been fired if someone wrote down dates, times, who said what, who did what, etc. But from a legality standpoint, no one in that situation had a real leg to stand on because it was basically all heresay. Backing up your claims with everything in writing definitely gives you more clout to the powers that be. If you don't, it seems to really keep their hands tied and they cannot give the appropriate punishment. Okay, off my soapbox!
