I tried not talking to her (she works in the same department as I do and is a new girl), and she complained to management that I was "refusing to speak to her," and I had to have a long discussion with the bosses about it.
I can't win for losing!
She sounds a lot like Holly from my college 3 years ago.
That girl RUINED my ENTIRE college experience. Just like you, I "thought we were getting along, too".
Then the threatening email, and the security guard's visit the next day.
I must say, that was a very low point in my life. Since then, I have found it VERY difficult to say much to a woman I am not sure of.
As far as I know, however a person CANNOT get someone for a "bad remark" if they don't make any!! SO...just say NOTHING to her, that is not necessary for work!!
LEARN from my heartache, and don't allow yourself to be crushed as I was!!
