This implies the concurrent action of several actors beside the occupational health physicians, such as ergonomists, psychologists, sociologists, educators, legislators, as well as managers and workers.
This is the only way to avoid an acritical assessment of mal-adaptation and/ or in-tolerance to shift and night work based on sectorial aspects (i.e. some individual characteristics or behaviours) not sufficiently supported by scientific data and longitudinal studies. This can also drive to a risky and even dangerous (i.e. for employment) attitude for selection of shift workers, without taking into consideration the whole context in terms of (shift) work organisation and social conditions, which in many cases are the major intervening factors and are more profitable interventions for subjects, companies, and the whole society.
