A new study published in Nature's Humanities and Social Sciences Communications journal has examined the practical experiences of 15 Australian firms implementing a four-day work week. The research focused on the '100:80:100' model, where employees receive full pay for 80% of their previous hours while maintaining 100% of their output.
Key Findings from the Trial
All but one of the participating firms decided to continue with the four-day work week, with none reporting a loss of productivity. Six companies even noted an increase in output. A primary motivation for six of the firms was to reduce employee burnout, a significant issue in Australia, with companies observing improvements in attrition and absenteeism.
Success Ratings and Outcomes
Overall, the firms rated the 100:80:100 four-day work week model with an average success score of 8.5 out of 10. The study highlights that the model can be a viable option for companies seeking to improve employee well-being without sacrificing performance.
- 15 Australian firms trialed the four-day week
- 6 companies aimed to reduce burnout
- All but one continued the model
- None reported productivity loss
- 6 reported productivity increases
The findings suggest that the four-day work week could be a sustainable approach for many organizations, offering benefits for both employees and employers.
