Ask:HN How to deal with people who take false credit from your work?

True the way he codes proves that he is unfit for the postion, it's not that I want to steal his job, but I want credits for what I do! Can't raise bug for everything, say for ex: He is working on something which he can't fix and the solution is so clear for him, he takes my help and in team meetings he says we did it and later on when he is reporting to the higher auth he claims that he only did the major part and I did nothing :\
