ANSES warns atypical working hours pose serious health risks

The French Agency for Food, Environmental and Occupational Health & Safety (ANSES) has issued an advisory warning that atypical working hours significantly harm worker health and social well-being. The agency estimates that between 55% and 75% of the workforce engages in such schedules at some point in their careers.

ANSES defines atypical hours through three main categories: weekend work, long shifts exceeding eight hours a day or 40 hours per week, and staggered shifts occurring between 5:00–8:00 and 19:00–00:00. These patterns affect a wide range of sectors, including healthcare, retail, agriculture, and public service.

Scientific analysis of 172 studies indicates that these schedules increase risks for cardiovascular disease, anxiety, sleep disorders, and metabolic issues, while also raising the frequency of workplace accidents. Henri Bastos, ANSES scientific director for health and work, noted that these rhythms cause a desynchronization from collective social patterns, leading to reduced recovery time and strained family and social lives. The agency is calling for better regulatory frameworks and protections, similar to those provided for night workers, to mitigate these risks.
