Let’s say you decided during an all-hands company meeting to publicly accuse your bosses of being bribed. You have no evidence to back up this claim, but you go ahead and attempt to humiliate them on a daily basis anyway. 

Let’s also say you’re running a division in the company that is losing $40 million per year. You have a bloated staff of more than 100 people while your competitor has a staff of less than 10 to produce a rival product, and that competitor is kicking your butt while actually making money for its parent company.
