Four-day week
Also called: 4-day workweek, compressed workweek
The two distinct models
“Four-day week” is overloaded — distinguish:
- 32-hour week, same pay: most common in published European trials. Employee works 32 hours across 4 days for the same salary as the 40-hour-week peer.
- Compressed 40-hour week: employee works 4 × 10 hours instead of 5 × 8. Same hours, different schedule.
In hiring, the first is a benefit; the second is a schedule preference. Confusing them in the job posting is a common candidate-experience failure.
What the European data shows
The 100 Companies (UK, 2022-23), 4 Day Week Global Foundation (Iceland, Belgium, multiple EU pilots) consistently find:
- Retention up by 20-30%.
- Application volume up when 32-hour weeks are advertised — sometimes 2-3x.
- Output broadly maintained in knowledge-work roles; in customer-facing roles results are more variable.
- Quality of hire: harder to measure cleanly, but no studies show degradation.
The mechanism for the volume effect: candidates see “32-hour week” in the posting and self-select toward it.
What it doesn’t fix
A four-day week doesn’t fix bad management, broken processes, or compensation below market. Companies adopting it for retention reasons sometimes find that the underlying retention problems were not about hours.
Where Join fits
