- Global trends, from Iceland's public sector to Dubai's 98% satisfaction.
📝Summary
ℹ️Quick Facts
đź’ˇKey Takeaways
- Four-day trials consistently show 100% pay for 80% time maintains or boosts output when paired with smart work redesign.
- Employee wellbeing improves dramatically: 71% less burnout, better mental/physical health, 62% less sick leave.
- Retention skyrockets—turnover down 57%, job apps up 88%—making it a hiring edge.
- Success requires commitment beyond just cutting a day; poor planning leads to failures like service backlogs.
The largest study ever, spanning 141 companies and 2,896 employees across six countries, slashed hours 20% without pay cuts. Results? 90% kept it permanently, stress plummeted, burnout fell 71%, and productivity spiked up to 40%. Even revenue soared—UK firms saw 130% jumps, US/Canada averaged 37% yearly gains.
Boston College researchers confirmed: nearly 33 companies reported productivity growth, less turnover, and lower health costs. 'Everything moved as expected,' said Prof. Wen Fan—no intensified work needed. Trials since 2019 by 4 Day Week Global show 92% retention rate worldwide.
Microsoft Japan gave Fridays off to 2,300 staff in 2019: sales per employee rose 39.9%, power costs dropped 23%, printing fell 59%, satisfaction hit 92%. Buffer's three-year run: 22% productivity gain, 88% more job apps, 66% less absenteeism, 91% happier staff.
BrandPipe's revenue exploded 130% during trial; CEO hailed wellbeing and performance wins. In US/Canada, 35 firms saw 8% revenue rise mid-trial.
Dubai govt hit 98% satisfaction, extending pilots.
Workers slept 16% more, mental health scores climbed 0.39 points, job satisfaction up 0.52. Trials cut turnover 57%, sick days 62%, with 58% of employees preferring it over raises.
Recruiting boon: apps surged as firms touted it.
Employers saved on healthcare, retained talent in high-burnout fields like teaching. 55% felt more able to excel in fewer hours—work ability sustained over six months.
UK now has 2.7M on four-day weeks (11% workforce).
Not a magic fix. Companies just 'lopping off' a day struggled—UK's Krystal faced backlogs and quit; Bolt reversed citing execution gaps. Success demands restructuring work, not shortcuts.
Critics note early-stage data; need longitudinal studies for full picture. Sector mismatches possible in shift-heavy roles, though pilots succeed in healthcare/manufacturing with planning.
Still, 90%+ stick rate shows it's no nightmare for most.
Evidence tilts hack: steady output, happier teams, business gains without extra grind. Iceland locked in shorter hours govt-wide; Tokyo boosts women via options.
As knowledge economies evolve, output-over-hours mindset wins.
To thrive, commit fully—redesign for efficiency. With trials proving transformative, the four-day week edges toward standard.
⚠️Things to Note
- Not all sectors adapt equally; works best in knowledge-based roles but needs tweaks for healthcare/manufacturing.
- Greater hour cuts (full 8 hours) yield bigger gains than minor reductions.
- Data is strong from pilots but critics call for more long-term, randomized studies.
- Some companies like Bolt reversed due to execution gaps, not the concept itself.
