I've got an unmanageable deputy, although I am doing my best. She's not very popular at work because she's a bit prickly and sulky, and she is the type of person who runs around looking busy whilst interfering with things she has not been asked to, sometimes causing problems for other people, whilst telling everyone how wonderfully efficient she is and how neglectful of my duties I am (which I am certainly not).
I have broad shoulders and believe it or not quite a good track record with dealing with difficult people, so up until now I thought I was coping with her quite well. However she is now turning very nasty indeed and tomorrow it is highly likely to come to a head and end up in her waving her hands and shouting at me and telling me she does everything around here while I sit at home, whilst I attempt calmly to defend myself point by point in a tit for tat way (hopeless, I know!)
I have found out whilst I was off on maternity leave she started being rude about me behind my back and on my return kept hold of a lot of seasonally related duties without telling me (eg started interviewing and appointing new staff without telling me and presented it as a fait accompli). She also misunderstood some key aspects of the role and made a bit of a mess of things while I wasn't there, which is starting to have a few repercussions (although she is not the sole reason for the problems, I have to say).
If anyone has advice or thoughts on this, I am all ears.
