A major company requested our advice on how to deal with anonymous complaints against managers in the organization. The had fear to speak up and there was a significant loss of productivity. We adviced the organization how to approach the matter in a multidisciplinary way and avoid a pure procedural approach to the situation. We met with the complainants in order to build confidence to speak up. By doing so, we could investigate the complaints and give the other parties the opportunity to share their viewpoint. We were able to explain the dynamics of the behavior and adviced the organization what kind of interventions, both preventive and protective, could be taken besides the legal interventions.
