Yeah I understand that. But are they lazy or don't know how to do their job? I mean if they don't really know how to do their jobs, perhaps they really aren't lazy at all but clueless. If they are truly lazy then they must know how to do their jobs but just don't. One solution is they need training the other is they need to be reprimended. Just trying to help.

Nothing is worth getting upset over like this if you can step back and approach it with an objective mind. If it's affecting your job I'd report it. If it's not and you can't realy do much about it, It'll do you good to just let it go. No one is worth the energy we spend on being upset at them. No one. and I say "we" because I'm not guilt free here either.
