The RATP’s Occupational Health and Safety Department has implemented a health promotion program for its employees that addresses work-related risks. This program takes into account the specific characteristics of the company’s working conditions: shift work; night work; prolonged periods of sitting—and thus increased sedentary behavior—; etc. The program was based in particular on the results of an epidemiological study conducted by the Occupational Health and Safety Department in partnership with Santé publique France. As part of an “outreach” initiative, medical teams organize short, interactive prevention workshops at workplaces on various topics, including healthy living in relation to shift work and addiction prevention. This holistic approach to health aims to give employees the tools to take charge of their own health.
