I have been working at my company for around 9 months. It is small place and I am having problems with a woman I work with. I was brought in with a couple of other people to drastically expand the company. They have a number of long standing staff who like the status quo and this seems to have made this woman feel threatened.
I really am clueless as to how to handle this one! She has been hostile since day 1. She has done numerous things, mainly nasty comments about me, complaining that I am not doing my job properly even though we are above target for this year and my manager is happy with me. She tried to discredit me to our colleagues and managers. She changes agreed procedures randomly in order to complain that I have not followed them. About two months ago, she tried to take over one of my sales relationships (we are both in sales), mess it up so the customer was complaining, and then get me to take it over. I thought it wise to challenge this as such a clear cut example and hopefully if this was bought to the CEO's attention (at the time, was managing both of us and only a small place), she would not risk similar behaviour again. I took this to our manager as this was a clear cut attempt to offload her work onto a colleague but he just agreed I should now take it on. I later found out she went to talk to him earlier before our meeting and lied saying that it was originally my sales relationship (completely untrue and can prove this from email exchanges). The CEO seems to support her regardless, and I am unsure why except perhaps they just don't want to confront her.
Since then, I thought it best to keep away from her and just ignore it. She is fortunately not based in my office so have been trying avoiding her. We recently had a new manager start and understandably he is keen to sort some of the 'systems' that are not working. These are all because she insists they are done a way that does not work. She continually interferes in my work and demands that I do things differently even though it is not in her remit remotely. It is tricky because if I go along with it I will fail to meet my targets as she is normally trying to get me to undertake my work in a way that I know will not work and will ensure I fail.
Since he has started to challenge her, she has responded by dragging her feet with things he needs her to do, and also become increasingly aggressive towards me. She takes my post so I am not able to respond correctly to it, has complained about me to this manager saying I am not doing my job properly because I was not scheduled to work on a day she decided she needed a question answering urgently. I strongly suspect she is trying to hide she is underqualified to this new manager and pull our team down so she doesn't look like she is underperforming as much as she is.
I got upset when manager pulled me into a meeting about this complaint. I said what has been happening and that I felt she wanted to harass me. I know I should have been more professional but it is just one thing after another. He seemed supportive but unsure what to either. He said he did not understand what she had a problem with either or how I was responsible for this.
Any ideas how to handle her or turn this around? I just dont know what to do.
