I am in a rather frustrating situation at work. My mat leave cover has been kept on in a temp position, reporting to me. She has been nothing but a pain in the neck. I think she is sour as she wants my job.
She spent first 3 months being moody, not doing things I asked and challenging me. However she made friends with a key person who sings her praises.
I then went on leave and returned to her trying new tactics which are to be extra friendly to all my team, to the point where staff ask me in confidence why she's changed. However she still challenges me and has tried to put me in a situation where she is good cop and I'm bad cop a few times.
I've let my boss know and they are fully backing me up but say that it's just a case of her temp cover ending. However there is a very big chance that the role will become permanent. It will have to be advertised but as she's been in the role not sure how she couldn't get it.
I hate working with her, she causes me stress, accuses me of micro managing (she makes mistakes a lot) and is very passive aggressive. I've tried to point this out to her and she then gets upset saying she can never please me and feels she's always in the wrong. She constantly puts blame on me and won't accept any responsibility. She accuses me of performance managing her and when I ask her why she's so defensive she says she doesn't know what I'm talking about.
How do I get through the next few months without blowing a fuse and more importantly how can I try to prevent this becoming a permanent arrangement!?!
