5. The Antagonist:

You can find many such people in an office who have the capacity of finding mistakes in the work you do. You can find such an attitude in your boss as well as in your co-worker. This kind of people will be desperately waiting for you to commit some mistakes from which they can get a chance of blaming you. An antagonist is the person who can find out the 1 mistake that has gone wrong and popularize it even though the rest 99 are good jobs. So, you must be very careful about such people.
