People in full-time employment work 40-hour weeks (usually 8 hours per day) from Monday through Friday in numerous nations across the globe.
However, other nations have shorter work weeks.
In Belgium, for example, workers generally work 38-hour weeks (7.7 hours each day), Monday through Friday. In Norway, workweeks are 37.5 hours long.
Companies in various areas of the globe, however, are increasingly experimenting with short weeks to examine how they effect employee productivity and general well-being.
For example, one New Zealand firm trialed a 4-day work week (32 hours) in 2018, and the results were so excellent that the company decided to transition to this model permanently.
Despite the fact that such tests seem to be effective, little study has been conducted to determine how many hours of paid labor per week are good to a person's mental health.
To examine this topic, academics from Cambridge University in the United Kingdom have started the project Employment Dosage.
"We have effective dose guidelines for everything from vitamin C to hours of sleep to help us feel better, but this is the first time the subject of paid employment has been posed," says research co-author Brendan Burchell, Ph.D.
Burchell and colleagues examined how changes in hours spent performing paid job affected the mental health and levels of life satisfaction of 71,113 persons in the United Kingdom from 2009 to 2018.
