Charles minor was not a bad guy.

People give him flack for being mean to jim but truthful jim did spend more time playing pranks goofing then working. Jim was not use to a compitant boss who is does not fall for his charm. Charles Minor felt a real life person brought to the office world and calls the show on its error how this is not how a real office should be like similar to frank grimes. What does jim expect when charles catches him on his pranks normal bosses would not put up with it. Plus jim tells him about the fake position he was appointed. When charles asks him the position entitled jim could not answer. SO charles did give jim time to explain. HE even gives jim chances to prove he is good actor by making rundown but jim does not know. Jim should know what it is . Dwight is the top salesman he is odd buthe puts more dvotion in work then jim so I do not blame him for treating dwight better. Aside from blaming jim in the soccer incident after accidentally kicking it coworkers face which was charles fault charles was a fair boss.
