I work in a large team, and have one colleague who has the same work area as me within the team. The rest of the team do other stuff, so she's my direct counterpart. She has been there a lot longer than I have, but we have the same role.
It quickly became clear after I started the job that she is totally out of her depth and is doing virtually no work. We have a shared workload and she has been working on one project for over a year. I have taken on more and more projects, and people have started to request to work with me and don't even include her any more in their emails. As such, I'm quite in demand and very busy.
We have weekly team briefing meetings where we update our Manager on our progress, and her updates are always full of waffle, she blames others for holding her back on tasks, or pretends she's done something which I know she hasn't. I honestly don't know what she does all week. (We all work from home)
I have raised it with my Manager on several occasions. At the beginning of this year, I raised it formally, and my Manager said she was aware that my colleague was struggling to deliver, and she had told her to focus on her one project and to reject any involvement in anything else to prevent her getting distracted so she could just get her project delivered. Manager promised me it would be finished within 6 weeks. That was in January, and she still shows no sign of finishing it. The latest was she had a deadline next week to submit part of the project, and she announced there was no way she could meet it, and it wouldn't be done until December.
It is driving me nuts. I'm horribly busy, and Manager is trying to protect me by fully supporting me in turning down any extra work. But it still really pisses me off that I'm so busy while my colleague goes from week to week delivering nothing, and lying during meetings about how busy she is.
I tried to raise it again with my Manager last week, but she just brushed it off. I have a constant turmoil of wanting to complain, but not wanting to seem petty or vindictive. It's not really impacting directly on me, as I have my own projects to do and I won't take on any more - but it's just so galling that she's getting away with doing nothing.
I realise that my Manager is not at liberty to share any information with me on what is being done about it. She has told me in the past 'We are aware, and it is being dealt with'... but.... I'm not seeing any evidence of anything changing.
What rights do I have to complain about this? And if I do complain - how do I word it without it sounding like i'm just being bitchy?
