Two Hundred UK Companies Sign Up for Permanent Four-Day Working Week

A century ago, the five-day, 40-hour workweek was a revolutionary idea—one that gave workers a break from the brutal six-day grind of the Industrial Age. It was a system built for factory floors, designed to maximize output in an era where manual labor drove the economy. But in today’s world, where technology allows us to automate, streamline, and complete tasks in minutes that once took hours, why are we still clinging to a schedule that no longer reflects how work actually gets done? If we can accomplish more in less time, does working longer really make sense?

Now, a growing number of UK companies are asking the same question—and rewriting the rules of work as we know it. Over 200 businesses have signed on to permanently adopt a four-day workweek without cutting pay, a move that many once dismissed as unrealistic or unsustainable. Yet, the early results tell a different story. Employees report feeling happier, healthier, and more engaged in their work. Businesses, in turn, are seeing boosts in productivity, better retention rates, and a competitive hiring edge. The traditional belief that more hours equal more productivity is rapidly crumbling, replaced by a model that prioritizes efficiency over exhaustion.

The Shift Towards a Four-Day Week: Rethinking the Way We Work

For decades, the five-day workweek has been seen as non-negotiable—a fixed structure that dictates when and how we work. But it wasn’t always this way. The idea of working Monday through Friday only became the norm in the early 20th century, when Henry Ford implemented it in his factories to improve worker productivity. Before that, six-day workweeks were common, and the notion of a “weekend” barely existed. What was once a radical shift in labor rights has now become so ingrained that we rarely question it. Until now.

The push for a four-day workweek didn’t happen overnight. Over the last few decades, studies have consistently shown that working longer hours doesn’t necessarily mean working better. In fact, research suggests that beyond a certain point, longer hours lead to burnout, lower efficiency, and even poorer decision-making. Meanwhile, countries like Iceland, Japan, and New Zealand have experimented with shorter workweeks, reporting not just happier employees, but also increased productivity and better overall business performance.

Now, the UK is seeing a movement of its own. The 4 Day Week Campaign, a UK-based initiative advocating for reduced working hours, has played a key role in encouraging businesses to make the switch. Their argument is simple: The way we work should reflect modern realities, not outdated industrial-era norms. Companies that have embraced the four-day model are finding that when employees have more time to rest, recharge, and manage their personal lives, they bring more focus and energy to their work. It’s not just about cutting hours—it’s about making work smarter, not harder.

More Work in Less Time? The Surprising Benefits

For many, the idea of working fewer days without a pay cut sounds too good to be true. How can employees be just as productive in four days as they are in five? Wouldn’t businesses lose money or struggle to keep up with demand? These were the concerns when companies first began experimenting with a shorter workweek. But as the results come in, they tell a different story—one that challenges long-held beliefs about work and productivity.

Employees who have switched to a four-day schedule report a noticeable improvement in their work-life balance. With an extra day off, they have more time to rest, spend with family, pursue hobbies, or simply take care of personal responsibilities that would otherwise be crammed into the weekend. This additional breathing room has led to lower stress levels, reduced burnout, and even better mental health. Studies show that happier employees are not only more engaged at work but also more creative and motivated, leading to higher-quality output.

For businesses, the benefits go beyond employee satisfaction. Several companies that have made the shift report increased efficiency, fewer sick days, and higher retention rates. With a condensed schedule, employees tend to work with greater focus, cutting out unnecessary meetings and distractions. In some cases, businesses have even seen a boost in revenue. When Atom Bank transitioned to a four-day workweek, job applications soared, and employee satisfaction increased significantly. Marketing agency Awin, which adopted the model permanently, saw a 15% rise in productivity.

Beyond individual companies, the potential societal benefits of a four-day week are significant. With fewer commutes, carbon emissions decrease. With more time off, local economies benefit from increased leisure spending. And perhaps most importantly, it forces a shift in how we define success—not by the number of hours worked, but by the results achieved. If working less leads to greater productivity, job satisfaction, and even economic growth, it raises an important question: Why hasn’t this change happened sooner?

Who’s Leading the Charge? Key Industries and Trends

Not every industry can easily transition to a four-day workweek, but certain sectors are proving that it’s not just possible—it’s a game-changer. The movement has gained the most traction in fields like marketing, technology, and NGOs, where work is often project-based and results-driven. These industries thrive on creativity, problem-solving, and efficiency, which means that longer hours don’t necessarily lead to better outcomes. Instead, companies are finding that when employees have fewer working days, they become more focused, waste less time in unnecessary meetings, and prioritize tasks more effectively. The result? Higher-quality work in less time.

London-based businesses are at the forefront of this shift, with many adopting the four-day workweek permanently after successful trials. These companies initially approached the idea with caution, concerned about whether it would impact profitability or slow down operations. Yet, time and again, they found the opposite to be true. Employees with more personal time returned to work refreshed, more engaged, and motivated to perform at their best. Some firms, like Atom Bank and Awin, reported higher job applications, increased retention rates, and even revenue growth—clear indicators that a shorter week is more than just a trendy perk; it’s a strategic advantage in attracting and retaining top talent.

However, the biggest question remains: Can businesses in industries like healthcare, retail, and manufacturing make this model work? Skeptics argue that sectors requiring round-the-clock services or customer-facing roles may struggle with the transition. But innovative companies are already exploring solutions. Some are implementing rotating shifts, compressed schedules, or staggered workweeks to ensure full coverage while still allowing employees to enjoy the benefits of a shorter work schedule. The reality is, the five-day week was once considered radical too, yet it became the norm. Now, the four-day workweek is proving that with the right mindset and structure, businesses across various industries can adapt—and thrive.
