workatrollic 

A colleague at work who is constantly negative about other colleagues' work. This person is also good at making you look bad in front of influential people such as managers.

Amir: So that guy actually told me my work is crap and his son designs better...! Later I heard from my manager that I should perhaps reconsider my position!
Elton: Gheez, he's such a workatrollic, he does this with every body.
