Australia Four-Day Work Week Study Data Shows Boosted Productivity

A new study published in Nature’s Humanities and Social Sciences Communications journal has confirmed what many workers have quietly hoped for: companies can switch to a four-day work week and not only survive, but thrive.

The research tracked 15 Australian companies that trialled the 100:80:100 model between 2022 and 2024.

The model is simple: workers receive 100% of their pay , work 80% of their previous hours , and commit to maintaining 100% of their previous output.

14 of the 15 companies chose to continue with the four-day week after the trial ended.

Not a single one reported a drop in productivity.

Six companies saw productivity actually increase.
