Changes in working hours and the associated time and energy consumed during work can exert an important influence on people’s fitness. However, the effects of such changes on health behaviour and obesity are not well understood. This column examines the effects of a 2001 French national reform that reduced working hours on employee obesity and overweight. Although reduced working times could, in theory, be used for health-promoting activities, in practice it had different effects on white- and blue-collar workers. Policies to reduce working hours alone do not necessarily produce better fitness for everyone.

Many firms are replacing traditional working hours with more flexible arrangements, reflecting new thinking on employee motivation. This column presents evidence from Germany that trust-based working time is associated with increased innovation. However, trust-based working hours also contribute to the blurring of workers’ professional and private lives, and may lead to excessive overtime. Careful design of trust-based working arrangements is required to reap the innovations gains while avoiding the health pitfalls.
