I am a manager, fairly senior position but within a large organisation so there are still quite a few layers of management above me. I get on really well with most of my team, but have been dealing with a particularly difficult team member for over two years now. The root of the problem is that the employee lacks the skills to do her job properly, not just in a few minor areas but in a serious and all-encompassing way. To put it simply, she adds no value to the organisation, and most people regard her as a liability.
My organisation moves at a very slow pace, and although I am going through the capability process with this woman, it keeps getting put on hold for various reasons - because she has taken out a grievance, because she has appealed against something, or because she goes off on long periods of sick leave. She has mental health problems, so we have tried to make reasonable adjustments, we have provided training, additional equipment and all sorts of other support, but nothing seems to make any difference. She just can't do the job.
HR is dictating the pace at which we move, and I feel like I am just a puppet - doing all the dirty work but taking all the flak. I have asked to take her through disciplinary, because she completely ignores all of my insructions, but HR have told me to focus on capability instead.
This woman is incredibly hostile and aggressive towards me, and I know that she has spread all sorts of unfounded rumours about me to others in the organisation. She is very personal and persistent in her attacks, and doesn't hesitate to tell blatant lies about me. Rationally, I don't think anyone really listens to her, but it hurts nonetheless and I feel constantly compelled to defend myself and refute her claims. I have also had to take on a lot of extra work to cover what she should be doing for me, and I am working very long hours as a result.
Basically, my job is making me ill. I feel physically sick when I see her, or read her emails etc, and increasingly when I just think about her. I can't sleep properly, and am getting lots of tension headaches. I can't switch off at the end of the day, and suspect my blood pressure has probably rocketed! I am also suffering from eczema again, after being clear of it for years. :(
I am just feeling so tired and low, constantly on the verge of tears. Friends have advised me to go off on stress-related sick leave, and I know I probably could, but I really don't want to - I just want to get on with my job. I really hate the unpleasantness of it all, and don't want to go to work to fight nasty personal battles. I have never felt this awful about anything in work before.:(
What can I do to keep the stress under control?
