Aim: Our objective was to develop and implement an intervention program in collaboration with workplace personnel, to evaluate the process as a vehicle to prevent and combat bullying. Methods: The project emanates from a community-based participatory approach. We obtained data from individual and focus group interviews. We used grounded theory methodology, and made a comparative analysis before and after the intervention. Results: Focus group interviews at the three first meetings indicated that those best positioned to prevent and combat bullying were the immediate supervisors, in collaboration with co-workers and upper management. The goal of zero tolerance toward bullying can be achieved if all concerned work together, using a humanistic value system, an open workplace atmosphere, group collaboration and conflict resolution. We developed an intervention, including lecturers and reflection groups, which ultimately resulted in an action plan. Focus group interviews at the fourth meeting, after the implementation, showed that employees were then more aware of bullying problems; the atmosphere at the workplace improved; the collaboration between and within the group was stronger; and the supervisor worked continuously to prevent and combat bullying, using the humanistic values suggested. We propose additional systematic work to implement our action plan and a conflict resolution system. Conclusions: The anti-bullying program implementation in the workplace achieved some success, but the intervention process is ongoing.
