I work in a fairly large organisation but in a small section; I'm a supervisor with one member of staff under me, our section is very busy.
But, my co-worker has a really, truly, horrible personality, and its getting to me lately. She's 42 but behaves like a sulky 6-year old. She makes a lot of mistakes and I always have to check her work. If I say nothing she thinks she's doing the job ok, so lately I've been (in a non- confrontational way) pointing out her mistakes. But this riles her and she huffs and puffs and makes pointed remarks about how busy she is and how hard she works and how she only gets paid a pittance. She makes a point of peering over my shoulder and questioning whatever I'm doing on screen, why am I doing it, who told me to, etc., but gets very defensive if I ask her the same.
I now feel that I was too nice and too keen not to upset her when I started in the post, and as a result she feels that she can walk all over me.
There was an incident a few months ago when she expressed herself very forcefully to me - told me what to say to my boss (nothing to do with my co-worker at all) in front of colleagues.
I told her the next day that while I knew she hadn't meant to bully me, that I had felt bullied, and that I couldn't put up with that. She was apologetic and was much easier to work with for a few weeks. Now however she prefaces every remark to me with "now I'm not bullying you or anything..." .
I have discussed this informally with my boss and asked for a transfer. I think I may have to speak to my boss again, but I really don't want to go down the route of making a formal complaint; I feel that I should be able to handle this myself.
Last week my boss questioned my co-worker over some silly mistakes she had made; this woman started sobbing after the boss had left and it took me and 3 other people the whole morning to calm her down, and she didn't do any meaningful work all day. She felt she was bullied but I felt she got offended way too easily - because she knew she had made silly mistakes.
She often mentions that she suffers from depression and has made some attempts to take her own life in the past. This makes me very wary of being confrontational with her.
I hope I don't sound unsympathetic but this woman's whole personality is warped. She hasn't a good word to say about anyone including her own family, she's judgemental of other people e.g. their style of dressing (too young for their age, too sexy, too much makeup etc.) and she's obsessed with money - her lack of it, how lucky other people with husbands are as they can "pay for stuff"! (I wish).
Its got to the stage where I dread going to work every day, although I've always loved my job and get on very well with my other colleagues.
Sorry this is such a long rant, but has anyone suggestions for either how to deal with herself, or maybe some coping mechanisms for myself? TIA.
