Wow, if HR has spoken to her and she has become worse... she must be a real (something starting with "B")!! I am very glad I don't have to work with her as she just sounds awful in every way. It seems so petty... I remember thinking in high school that things would be better when we are all grown up... but people still act much the same.
I wonder what her problem is? Maybe she is threatened by you? Or jealous? or maybe just a sociopath!!
It is so hard at work because in other situations it is simple, if someone acts like that you just cut that person out of your life. At work we are stuck with these people and have to tolerate them somehow. It would be nice if you just never had to see her again. How are the other people you work with? Hopefully they see what she is like and realise what she is doing to you, hopefully they understand how she is making you feel and support you. If they don't, I wonder is this problem worth leaving this workplace for? It might not seem like it now, but the longer it goes on the worse you will feel, it might be a good idea to look for a better work environment elsewhere.
If you do need to stay and leaving isn't an option, I would definitely keep a record of her behaviour... anything unprofessional that she does, the time and date etc and if HR are ineffective, maybe you could go above them? If you like your job and are otherwise happy where you are, perhaps with the evidence you give it would be grounds for them to fire her?
The last option I can think of is to confront her... but this is a bit scary and could make things better or worse... in a perfect world, you could explain how she makes you feel, she would understand and apologise and change her behaviour. She doesn't seem like the type.... but I guess sometimes you can't predict what people will do?
What do you think?
