I don't know whether this will translate into French because it's an alliteration in English. This is so common, moving someone who has been found to have been a sexual harasser to another job. We call it pass the perpetrator. It happens all the time and it's completely inappropriate.
Individuals who have some sort of pattern of harassing either need to be educated....There needs to be an intervention of some sort for the person, not simply a sanction, but also some sort of intervention if you're going to keep them in the workplace, because if they have not changed their behaviour, obviously they are going to do it somewhere else.
Having said that, I'll recommend another researcher to you. His name is Dr. John Pryor. He has done research which shows that men differ in their likelihood to sexually harass, but even men who have a high likelihood to sexually harass, based on a measure he developed, will not harass if they are in an organization where there are sanctions and things he calls management norms, where the managers are modelling this. Sometimes it's the manager who is actually doing the harassing. That's communicating to the men in the organization that if their boss is doing it, they can do it too.
Dr. John Pryor has some good things to say about offenders.
