Good Leaders Prevent Bullying
Workplace bullying happens much more often in organizations with poor management. An article in the Journal of Occupational Health Psychology examined hundreds of bullying complaints and found that bad people management greatly increased the risk. That might be why anti-bullying strategies focusing on the individual has had so little effect. It also explains why bullying is much more common in organizations where the team leader is simply the person who has been doing the work the longest.
One positive aspect of this finding is that good leaders can prevent bullying. If you are a victim of workplace bullying, you might not need to quit the organization. You might be able to transfer to a team with a good leader instead.
