Aim of special session This session is expected to be interactive, providing the attendees with both an understanding of the social and physical harm than may come with working shifts, and an evaluation of different countermeasures developed to help ameliorate these problems. The question and answer portion is meant to be both ‘ask the expert’ for those just entering this area of occupational health, and an interchange among the research delivery communities on what else may or may not help and why.
