I ratted my friend and coworker out to management.
What happened to make you do this?
First I compared his products to the manual, he got so mad at me, but I still included him in my report. He got fired.
It's understandable to want to have competent co-workers, buts its immoral to rat someone out if it gets them fired over something so petty. He may need that income to afford bills or support a family.
I know, but he started it.
It is rude to snitch on people if they are having a hard time and not hurting others. You could have taken him aside and shown him the proper way to do things before getting him fired.
