The aim of the present study was to explore preventive strategies and processes to counteract bullying in workplaces. Data were collected by individual interviews and focus group discussions at one hospital and two nursing home wards for elderly, a total of 29 participants. In the analysis of the interviews we were inspired by constructivist grounded theory. Persistent work with a humanistic value system by supervisor and coworkers, raising awareness about the bullying problem, strong group collaboration, and conflict management, along with an open atmosphere at the workplace, appears to be imperative for accomplishing a policy of zero tolerance for bullying.
