Okay. Here goes.
I have worked in my current role for six years, having spent seven years working in the sector elsewhere. I am highly qualified and am relatively senior. I was the first 'new' person appointed at any level for years (internal promotions had happened almost by default) and no-one new has been appointed since so I am still the new girl. In these 6 years I have gone p-t and had one 8 mo mat leave. This is all relevant.
One colleague (been there longer than me but a lower grade) decided during my first week that I was incompetent. Let's call her T. At every opportunity she has criticised not in a constructive manner, always in front of others and has what she picks on is crazy: I used a split infinitive once and she pulled me up on it. It's laughable but she is very unpleasant with it.
In 2010 I had my dc2. T went for my cover but was not appointed. Her campaign intensified and she got into the habit of e-mailing me with 'urgent' things when I am going home, as in, she sees me with me coat on. I should say that I have been part-time for 5 years and T is under the impression that I am expected to work on my day off: this is not the case at all. She also informed me that I was contractually obliged to deal with messages on my days off. Again not true!
Eighteen months ago we had a major restructure and I find myself in a more senior position. I am not paid a penny extra and I am relishing the opportunity to gain this experience. My manager is being very supportive - almost taking on a mentoring role.
T is being awful. Just awful. She has decided that I should not be in the position I am in because I don't know about one tiny thing. True, but nothing a five minute conversation would resolve. She refuses to do anything, but instead blames me for everything that goes wrong. She has responsibility for one particular area where she truly is an expert, but has decided it should all come down to me. She is rude in meetings - finger pointing, aggressive language - and sends urgent messages to me on my days off, then follows up with another message asking why I haven't done what she passed to me!
All this has been witnessed but so far my manager hasn't done anything because I can to a point defend myself and don't tend to put up with it. But I cannot cope anymore. I do not deserve it. I am trying to find a new job but that job hasn't materialised yet. Resigning is not an option and the bottom line is why should I!
I don't know what to do.
