Thank you for the question. There are models around the world. The one I personally prefer is the Belgian model. It requires une personne de confiance, whose full-time or part-time job, depending on the size of the organization, is to be the person to whom everybody can go to anonymously to address concerns. When they first adopted the law, it was only for psychological harassment and sexual harassment, and now they also include psychosocial hazards, which come before the actual manifestation of violence. The personne de confiance would be the first person who would be able to address it.
