Of course, nothing is so black and white as just firing people based on the below info, but it does have a grain of truth to it.
Fire These Three People In Your Organization Right Away
The victim. This is the person who sees problems as occasions for persecution rather than challenges to overcome. The persecution apparently comes in the form of you name it — humans, processes, and inanimate objects with equal ease. And if there isn’t a problem, the victim will find one. The victim is often angry, usually annoyed, and almost always complaining. Note to HR: After termination, the victim will no doubt look for someone like you for sympathy and agreement that the world is against him.
The nonbeliever. This person lives by the Henry Ford quote: “If you think you can or think you cannot, you are correct.” Winners really believed they can do it; losers (nonbelievers) always doubted it was possible. The link between believing and succeeding is powerful and real. So is the link between nonbelieving and failure.
The know-it-all. The best innovators are learners, not knowers. The same can be said about innovative cultures; they are learning cultures. Those who think they have nothing to learn will invariably be overtaken by learners, or will drag down an organization and let the competition overtake the organization. They never see new things coming because they think there are no new things. That’s how it is when you think you know everything.
