Bullies are incompetent
Last week, a UK government minister was fired for bullying. Mysteriously, the new Prime Minister brought Mr. Williamson back into government after he had already been fired as a minister twice before over other scandals.
Bullies are often trying to cover their own lack of competence by putting others down. In a cut-throat environment where everybody is fighting everybody else, there will be much more bullying. When looking for a job, ask about their bonus system. A company with large individual bonuses will have more bullying, no matter how many anti-bullying policies they have.
