When a female chief executive at a medium-sized health tech firm sat down to redesign her company's work schedule, she wasn't chasing profits—she was chasing her employees' wellbeing. That decision, to trial a four-day work week across 15 Australian companies, has upended a century-old assumption about how work gets done.
The stakes feel particularly urgent right now. A 2025 Beyond Blue survey found that one in two Australian workers face burnout, with young people and parents bearing the heaviest burden. Meanwhile, research shows Australian workers are regularly donating an extra 3.6 hours of unpaid labor each week—a gap that grows wider as AI promises to reshape productivity entirely. Last month, OpenAI itself called on employers to experiment with four-day weeks as a way to fairly distribute the gains that artificial intelligence is predicted to deliver.
Over two years, researchers interviewed 15 Australian firms that implemented the 100:80:100 model: full pay, fewer hours, same output. The companies spanned industries from logistics and property management to healthcare and publishing, ranging from tiny operations with two employees to medium-sized firms with 85 staff. What they discovered challenges the productivity-obsession that has long defined modern work.
The motivation to switch, surprisingly, had little to do with efficiency. Six of the 15 companies explicitly named burnout reduction as their primary driver. One financial services executive captured the philosophy plainly: "We felt that when we sat down with clients every day, and we were encouraging them to live their good life, that it was a little rich if we didn't do the same." The health tech CEO measured success not in revenue metrics alone, but in attrition rates, absenteeism, and the number of employees taking mental health days—a refreshingly human framework for assessing organizational health.
By the time researchers wrapped up interviews between early 2023 and late 2024, 14 of the 15 participating firms were still running the model, either extending their original trial or moving to permanent adoption. One firm stepped back, but acknowledged that timing—not the model itself—had made the shift impossible. A different organization had already been operating the four-day week for nearly eight years.
The productivity question, which looms largest in most policy debates, answered itself quietly. Six organizations reported that productivity actually increased. The remaining firms said it stayed roughly the same. Not a single company reported a productivity decline. These assessments drew from each firm's own metrics—revenue, profit, on-time project delivery, customer loyalty scores—making the consistency of results even more striking.
When asked to grade the experiment overall, participating firms awarded the four-day week an average success rating of 8.5 out of 10. One firm's extended eight-year commitment speaks louder than any score.
The research does acknowledge its limitations: the 100:80:100 model remains relatively new, and the number of Australian organizations running it is small. But as burnout rates climb and AI reshapes what "productivity" means, these 14 Australian firms have quietly demonstrated something radical—that working less, paid fairly, can actually work better. The question now is whether the rest of the world is paying attention.
