I've been in my current job for 5 years now, started at the same time as this other girl. We trained together. I did pretty well on the training, she struggled. I only add that in as a guess as to why she's been absolutely awful to me since then.
Unfortunately I sit opposite (diagonally) from her and so we spend hours of the day in each other's eyeline. She talks to other people, always texting other people in the office, calling them up when she's not in, but will barely even look at me. When I talk to her, she'll talk back through gritted teeth. If I come into the office and she's already there, her whole body stiffens and she'll go stony silent for hours.
The other problem is, if she sees me talking/making friends with other people, she'll start being friendly to them and sort of get them under her control, so they end up being mates with her. She's isolating me.
Has anyone got any idea on how to cope with this situation?? I've spoken to my line manager about it who tells me to just carry on doing my job regardless but it makes my days miserable having to put up with this behaviour. He says maybe she's jealous because I did better in the training. But 5 years on and she still bears a grudge??? She is very up the manager's you know what. Other people in the office either can't see what's going on or just turn a blind eye to it.
WHAT am I going to do?? I could leave my job but why the hell should I???
Please Mumsnetters, any advice gratefully received!!
