Workplace bullying is a phenomenon that is attracting increasing interest from researchers throughout the Western world. To date, most of the research into workplace bullying has focused on managers and colleagues as the perpetrators of bullying in the workplace. By contrast, little is known about ‘upwards bullying’, where managers are the targets. We argue that in order to more fully understand workplace bullying as a whole, the phenomenon of upwards bullying requires research attention. In the present study, upwards bullying was explored in interviews conducted with 24 managers from public and private organizations, with the data coded and arranged thematically. Results indicate that potential contributing factors towards upwards bullying include the current work environment, change within organizations and power issues. We recommend that organizations identify the occurrence and processes of upwards bullying as important steps in developing comprehensive workplace bullying policies.
