If you don't find those numbers alarming, consider that the data indicate employers most typically respond to allegations of bullying by denying that it occurred or discounting and rationalizing the conduct. Moreover, the perpetrators are overwhelmingly male superiors.
But perhaps least surprising: minorities, females, and other more vulnerable employees are most likely to suffer bullying in the workplace. (The targets of workplace bullying were most often described by co-workers as compassionate & kind, cooperative and agreeable.)
The good news is that despite employer inaction, slightly more than half of the co-workers of bullying victims do something to try to help.
