In an era where burnout and blurred work-life boundaries have become commonplace, the four-day workweek is emerging as a promising solution. A large-scale global study, conducted by researchers from Boston College and University College Dublin and published in *Nature Human Behaviour*, has found that a shorter workweek can enhance employee well-being without sacrificing income. The study involved nearly 3,000 workers from 141 companies across the US, UK, Australia, New Zealand, Canada, and Ireland that implemented a four-day workweek between 2022 and 2024.
The research revealed that shifting from a five-day to a four-day workweek led to notable improvements in various metrics of employee health and satisfaction. Participants experienced a 16% reduction in burnout, a 7% increase in job satisfaction, and enhancements in mental health and physical wellness—improvements of 13% and 9% respectively. Unlike the control group, which maintained a traditional work schedule, companies that participated in the trial provided their employees with 100% of their pay for 80% of their working hours.
Furthermore, the study identified key reasons for these positive outcomes: better sleep quality, reduced fatigue, and an increased sense of work ability among employees. Companies that carried out the trial not only reduced work hours from an average of 39 to 34 per week, but they also restructured workflows to eliminate unnecessary practices and foster greater collaboration within teams.
The findings indicated a “dose-response” effect—the more hours employees cut, the greater their mental and physical health improvements. While smaller reductions in hours still yielded positive results, more significant cuts provided the most substantial benefits.
This initiative aligns well with ongoing discussions regarding employee well-being, as other organizations like the Suva City Council (SCC) also stress the importance of work-life balance. The SCC has allocated $1.5 to $2 million each year for overtime payments, recognizing that excessive work hours correlate with lower productivity. Chair Tevita Boseiwaqa highlighted that balancing workload with employee health is critical for enhancing overall effectiveness.
The momentum behind the four-day workweek indicates a shift toward reimagining work norms that have persisted for over a century—a shift that could help mitigate burnout and promote healthier work environments. While this model may not be a universal remedy, the evidence suggests it could be a valuable tool for improving worker well-being and productivity when implemented thoughtfully.
As discussions around labor practices continue, the hope remains that frameworks promoting employee health and sustainable productivity can emerge, leading to happier, healthier workplaces across various sectors.
