Many national and international studies show that some effects of the current transformations of work (intensification, production organization ...) affect more and more mental health workers. If the physical health and safety has long been the subject of legislative attention as doctrine, alterations in mental health at work are still not at the centre of specific legal provisions. The concept of "psychosocial risks", however, is apprehended by different scientific disciplines (psychology, medicine, sociology ...). If a few legal studies and research and surveys about social actors were conducted, none have actually attempted a critical comparison of the French legal system to foreign systems in the field.
Moreover, when occupational health issues in France includes the suffering, there is great difficulty in understanding and acceptance of legal framework edited by social and legal practitioners. Before considering the effectiveness, we must in mental health at work to question the reception of legal devices. Basically, the research program will aim at a state of legal recognition, the terms and prevention of harm to mental health at work. The use of comparative analysis (Northern and Southern Europe, Canada, Japan) is on the one hand a broad approach and diversified inventory, the other to highlight the French specificities.
