I've been in IT Industry since 1999 and been working with many people, however there was always that one co-worker that just rub me the wrong way..

For me it was always one of those co-workers "Know it All" or "Let me try to put you down upfront of 20 people and act like I know sh**"

So what's your most disliked attitude in workplace?
