5.5 to 6 Days of Work: Is It Time to Seriously Change?

Thailand ranks 3rd globally for longest working hours — yet productivity per hour tells a very different story.

Nearly 46.7% of Thai workers exceed 48 hours per week. Thailand ranks 96th out of 100 countries for work-life balance.

Real-World Case Studies

Microsoft Japan tested a four-day workweek and saw productivity rise by 39.9%. Similar trials across Iceland and Europe show improved wellbeing without productivity loss.

“The majority of the Thai workforce already experiences burnout symptoms. The cost of replacing burned-out employees often exceeds the cost of prevention.”
