This one was good, though: We got a new NCOIC (the sergeant in charge.) He wanted my space for his office, until I pointed out all the equipment I had that would have to be moved (special printer, modem, two computers, two file cabinets, my books. I stayed where I was.
Unlike you, Evil Coworker (ECW) coveted my spot so she got Evil (Now Former) Supervisor (ENFS) to trade our cubicles (and she lied that she was the one that prompted this trade since it made absolutely no sense -- our cubicles were next to each other and shared a wall). Because I was put in her old cubicle, the lighting was a lot stronger and was causing me physical difficulty (caused increasing pressure in my head). So, I did what I was told (by another party) would be okay -- I contacted maintenance to reduce the lighting above my cubicle. When maintenance showed up to do so, ECW had a major cow on the floor then, as always, ENFS came out and started berating me right in front of the maintenance guy (also a hospital employee so someone who could file an internal complaint regarding what took place). Nice Coworker (who, I didn't know, had been witnessing the harassment and bullying of me since day one of my employment) finally had enough, went to our department director and not only told him what happened but how long it had been happening (which finally confirmed my complaint 1.5 years prior that ENFS was harassing me -- he lied when confronted and I couldn't prove it so, except for a few months of peace, he went back to what he was doing as it brought pleasure to ECW).
Anyway, happy ending, since I finally had someone who could corroborate my story, I knew I could go in with power behind my complaint, insisted that ENFS be removed as my supervisor since he had proven he could not be trusted to be an impartial supervisor and I got moved to the other end of the office. Life has been much better for over 1.5 years now, and that has chapped ECW's hide even more. All this took place just because she had to try to stick it to me yet again and take my cubicle (and given that my area had to decide among them who would be my supervisor, the entire office knows what those two had been doing for 2.5 years).
BTW -- if someone here is wondering why NCW (and others around us who I didn't realize could hear everything) didn't step up and say something sooner -- I really don't know. It never occurred to me when I first complained that there were any witnesses to what was going on, and I can't/won't fault them for not getting involved (and, since I didn't talk to any of them about what was going on, they might've wondered why in the world I was putting up with it). I think it was when I got berated in front of someone from an outside department, thus making OUR department look horrible, that it was the last straw for NCW.
