If you feel that your boss is kind, chances are you look forward to going to work every day, you’re more likely to put in a little extra effort, and you might even delay that search for a new job. But if you work for a boss who is a bully, all bets are off. That’s according to new survey conducted by American Management Association (AMA) that examines how a boss’ character affects employee performance and retention rates.

AMA surveyed 662 members and customers on a number of workplace issues and character traits. First the good news: 75% of respondents regarded their supervisors as “kind.” Now the bad news: 14% of respondents indicated that their supervisors were, in fact, “bullies.” The remaining 11% were neutral about their bosses’ character. According to the survey results, kind managers are associated with superior performance along a number of dimensions.
