Confirming the positive findings of multiple studies across the world into reduced time working arrangement, the results of a medical trial in the UK show the physical and mental benefits for workers.
Researchers from University of Sussex followed workers at Thrive (a technology learning company trialling a four-day work week) for three months, conducting MRI scans, blood tests, sleep tracking and questionnaires with the employees. They also gathered data from customer feedback to assess service quality levels, and sales and product metrics to measure productivity levels.
The results showed a 21% increase in overall well-being, including less stress and emotional exhaustion, while participant sleep problems fell by 20%.
Perceived levels of emotional exhaustion or burnout reduced (14.7%), as did stress (8.6%) and anxiety (5%). Overall, the participants reported an increase of 11.4% in personal accomplishment. Productivity levels were positive, and staff reported a 19.4% increase in goal attainment.
Research Lead, Dr. Charlotte Rae said, “Improved sleep quality and reduced stress and exhaustion are factors that could have a significant impact on our health.”
Four-day work weeks have been growing in popularity over recent years, with the Covid pandemic leading to increased stress, burnout and exhaustion for many employees. In the US some policy makers are pushing to reduce the standard work week to 32 hours, arguing that the change would give workers, including those who can work remotely, a share in the benefits of technological advances and economic growth.
