For decades, the 40-hour, five-day workweek has been a fixture of American business culture. But in recent years, an old idea has made a bold return: the four-day workweek. Around the globe, companies are putting the traditional model under the microscope; experimenting with reduced schedules, without slashing pay, and seeing surprisingly strong results.

The question is no longer just whether a shorter workweek can work, but whether it should be the next evolution of the modern workplace.

Global Trials Are Challenging the Status Quo

In 2022 and 2023, high-profile pilot programs in countries like the UK, Iceland, Japan, and New Zealand tested a four-day model with promising outcomes. One of the most extensive studies came from the UK, where over 60 companies took part in a six-month trial coordinated by 4 Day Week Global and academic researchers.

The result? 92% of the participating firms decided to continue with the shorter week. Employees reported lower stress levels, improved work-life balance, and reduced burnout, while companies maintained—or even improved—productivity and revenue.

Iceland’s earlier national trial showed similar outcomes. Between 2015 and 2019, around 2,500 workers shifted to a reduced work schedule. Productivity either stayed the same or improved in most workplaces, and employee well-being rose across the board.

The evidence is stacking up, and it paints a compelling picture: more time off doesn’t necessarily mean less work gets done.

So Why Hasn’t the U.S. Jumped on Board?

In the United States, the idea is gaining traction, but slowly. While some companies, particularly in tech and creative industries, have adopted the four-day workweek, large-scale implementation is still rare. Skepticism remains, especially in industries that rely on hourly work, client service, or traditional expectations of availability.

For many U.S. employers, the concern boils down to feasibility. Can productivity really be maintained with fewer hours? Will customers suffer from reduced service windows? And is the workforce ready to make that shift?

These are valid concerns, but they may not be dealbreakers.

What U.S. Companies Should Consider

Before deciding if a four-day workweek is viable, leaders need to look inward. What are the key metrics driving business performance? Is your team’s productivity outcome-based, or time-based? Can workflows be streamlined, or meetings reduced to make better use of time?

A trial period, such as a 3-6 month pilot, could offer insights without long-term commitment. During the pilot, companies can monitor employee satisfaction, client feedback, and business outcomes. It’s not a one-size-fits-all model, but for organizations open to flexibility and innovation, it might just be a game-changer.

The Bottom Line

The global four-day workweek experiments have made one thing clear: rethinking the structure of work doesn’t have to mean sacrificing results. For U.S. businesses willing to challenge old norms and embrace data-driven experimentation, there’s real potential here.

As talent expectations evolve and burnout remains a concern, the question isn’t just whether the four-day workweek can work, but whether companies can afford not to try it.

Would your business benefit from a four-day workweek? It may be time to find out.
