I'm going to go up to a coworker and call them a rat-faced goblin.
Why are you going to insult your coworker?
He has given me much trouble lately so I think he deserves it
You shouldn't call your coworkers names. First off, it can get you fired, secondly, it could cause problems with other people at work.
Yeah, I agree. I should try to get along with others.
It's great that you are willing to see the change that needs to be made. By not calling your coworker names you will able to maintain a professional appearance at work.
