Jim, I had a couple people working under me a couple years back - I was the Internal Comms manager for an IT firm [before I opted to become a professional bum] and I NEVER knew that the bloke was a lazy twat, cos everything I asked him and the bird to do was done.

ANYWAY, he had 2 weeks holiday and I was expecting to have to do some of his sh!t whilst he was away, turns out the bird got on better without him there and actually had more time to spare???

To cut a long story short, there wasn't a great deal I could do to get rid of him as he always met his targets and personal objectives [it was a American wannabe company]

So when I left, I helped find my replacement and helped get the bird my job. She got a nice £8k payrise, car allowance and flexible benefits for her trouble. He got a new boss and lasted just over 2 months before he left

HAVING SAID THAT, if she'd whinged to me about him, I'd have got annoyed cos I was busy as feck, she did mention it whilst he was away, in confidence, in a very well angled way.... maybe you should try that to your boss? Don't whinge else you'll just get a black mark......

But these type of people always get found out sooner or later
