BOOK REVIEW
Do More in Four: Why It's Time for a Shorter Workweek, by Joe O'Connor and Jared Lindzon, Harvard Business Review Press, 13 January 2026, 240 Pages, $32.00 (Hardcover), ISBN 9798892791458
It begins not with a manifesto about leisure, but with a small, almost banal observation repeated across workplaces that experimented with a four-day week: nothing collapsed. Clients did not revolt. Deadlines did not implode. Meetings did not suddenly become sacred. Instead, people worked differently. They cut what never mattered, delayed what never should have been urgent, and protected the few hours where thinking actually happened. This deceptively modest insight animates Do More in Four: Why It’s Time for a Shorter Workweek by Jared Lindzon and Joe O’Connor, a book that treats the four-day week less as a lifestyle perk and more as a structural correction to a century-old mistake.
The timing of this argument matters. Today, 1st May 2026, marks one hundred years since Henry Ford introduced the five-day, forty-hour workweek in his factories. When Ford shortened the workweek in 1926, reducing the prevailing six-day grind, the move was hailed as progressive and humane. It was also ruthlessly strategic. Ford understood that exhausted workers were inefficient workers, and more importantly, that workers without leisure could not become consumers (Raff & Summers, 1987). The two-day weekend created time to rest, but also time to spend, particularly on Ford’s own automobiles. What followed was not a moral awakening but an economic cascade. Other firms followed to prevent attrition, and by 1938 the Fair Labor Standards Act formalized the forty-hour week in US law. The five-day workweek was not designed for knowledge work, creativity, or care labor. It was designed for factories, assembly lines, and physical output measured in hours.
Lindzon and O’Connor argue that we are still living inside that industrial scaffold long after the scaffolding stopped making sense. Do More in Four positions the five-day workweek as an artifact rather than a law of nature. The book’s core claim is simple but unsettling: if the structure of work was historically contingent, then it can be historically revised (Kipping & Üsdiken, 2014). The four-day week is not framed as a utopian fantasy, but as a pragmatic response to how work actually happens today, especially in knowledge-intensive, digitally mediated, and AI-augmented environments.
One of the book’s strengths is its refusal to romanticize time-off. The extra day is not presented as a gift, nor as a wellness indulgence. Instead, Lindzon and O’Connor insist that reducing the workweek forces organizations to confront how much of their time is wasted by default. Meetings expand to fill calendars. Emails substitute for decisions. Visibility masquerades as productivity. When a day is removed, these habits are no longer affordable. The four-day week becomes an organizational stress test, revealing which practices create value and which merely create noise.
This is where Do More in Four aligns closely with Cal Newport’s Deep Work (2016). Newport’s central argument is that high-value cognitive labor requires sustained, distraction-free concentration, yet modern workplaces are structurally hostile to such focus. Open offices, constant messaging, and performative responsiveness reward shallow work while crowding out deep thinking. Lindzon and O’Connor extend this insight from the individual to the organizational level. A four-day week, they suggest, is not simply compatible with deep work; it actively incentivizes it. When time is scarce, organizations are forced to protect focus rather than squander it. Deep work stops being a personal productivity hack and becomes a collective norm.
The book’s empirical grounding gives this argument credibility. Drawing on large-scale trials coordinated by 4 Day Week Global, the authors document cases where productivity held steady or improved despite reduced hours, while burnout, absenteeism, and attrition declined. These findings challenge the intuitive but flawed assumption that more hours necessarily yield more output. Instead, they echo Newport’s distinction between activity and accomplishment. The four-day week does not ask people to work faster in a frantic sense. It asks them to work more deliberately.
Alex Soojung-Kim Pang’s Rest: Why You Get More Done When You Work Less (2016) provides the physiological and psychological foundation for this claim. Pang’s research shows that elite performers across disciplines structure their lives around cycles of intense effort and genuine rest. Creativity, insight, and sustained excellence depend on recovery, not endurance. Do More in Four operationalizes this logic at scale. The fifth day off is not an absence from work, but a condition for better work. It enables cognitive recovery, emotional regulation, and the kind of mental spaciousness where novel solutions emerge.
What distinguishes Lindzon and O’Connor’s contribution is their insistence that rest must be structural, not discretionary. Wellness programs fail, the book argues, because they place the burden of recovery on individuals while leaving the system untouched. Meditation apps do little when workloads remain unreasonable. Unlimited vacation policies mean little when no one feels safe taking time off. A shorter workweek, by contrast, hard-codes rest into the rhythm of organizational life. It removes the moral ambiguity around stopping work. Everyone stops together.
The book is especially persuasive when it traces how the five-day week became normalized despite lacking any natural or moral foundation. There is nothing inherent about seven-day weeks or five-day labor cycles (Hamermesh & Biddle, 2025). These patterns emerged from religious compromise, industrial convenience, and managerial control, not from human biology or optimal performance. By historicizing the workweek, Do More in Four makes it easier to imagine alternatives. The five-day week is revealed as a habit masquerading as necessity.
This historical perspective also clarifies why resistance to shorter weeks persists. Critics often frame the four-day week as laziness or entitlement, echoing the same objections raised against the eight-hour day and the weekend itself. Lindzon and O’Connor show that such arguments confuse hours with effort and presence with value. In a knowledge economy, output is uneven, nonlinear, and often invisible. Measuring commitment by time spent is not only inaccurate but counterproductive.
The book’s discussion of artificial intelligence sharpens this point. AI tools already allow many workers to complete tasks in a fraction of the time previously required. Yet instead of translating these gains into reduced hours, organizations often respond by raising expectations. Productivity improvements are absorbed upward rather than shared outward. Do More in Four challenges this pattern directly. If technology increases output, the authors ask, why does leisure remain static? Why does efficiency never convert into time?
Here again, the Ford analogy resurfaces. Ford understood that productivity gains had to be redistributed to sustain the system. Lindzon and O’Connor argue that the same logic applies today. In an AI-enhanced economy, the choice is not between working less or remaining competitive. The choice is between sharing efficiency gains or intensifying burnout.
The social implications of this argument are significant. The book devotes sustained attention to gender equity, caregiving, and demographic change. The five-day workweek was designed for a household with a full-time male breadwinner and a full-time female caregiver. That household no longer describes reality. Dual-income families, single parents, and aging populations strain under schedules that assume someone else is always available to absorb life’s contingencies. A four-day week does not solve these problems, but it redistributes time in ways that make care more visible and more shared.
Environmental benefits also emerge as a secondary but meaningful effect. Fewer commuting days reduce emissions. More discretionary time encourages slower, less carbon-intensive forms of living. Unlike many climate interventions, a shorter workweek offers a positive vision rather than a sacrificial one. It frames sustainability as gain rather than loss.
Importantly, Do More in Four does not pretend that implementation is easy. The book is careful to distinguish between naive reduction and deliberate redesign. Organizations that simply cancel Fridays without rethinking workflows tend to fail. Those that succeed treat the four-day week as an operational excellence project. They audit meetings, clarify decision rights, invest in asynchronous collaboration, and redefine productivity around outcomes rather than hours. The extra day is earned, not assumed.
This emphasis on redesign is where the book is most practically useful. Lindzon and O’Connor offer a blueprint rather than a slogan. They show how pilots can be structured, how metrics can be set, and how reversibility can be built into experiments. The four-day week is framed not as an irreversible leap of faith, but as a testable hypothesis. If it does not work, it can be withdrawn. That conditionality makes the proposal palatable to cautious leaders.
Yet the book is not merely managerial. It is also moral, though quietly so. Beneath the data and case studies lies a deeper question about what work is for. The five-day week assumed that work was central and life peripheral. Do More in Four inverts that assumption without rejecting work itself. It argues for a model where work is intense, meaningful, and bounded. Time outside work is not an escape, but part of the same system of human flourishing.
In this sense, the book is best read not as a manifesto against work, but as a manifesto against waste. Waste of attention. Waste of energy. Waste of lives spent proving busyness rather than creating value. On the centenary of the five-day workweek, Lindzon and O’Connor invite us to recognize that yesterday’s innovation has become today’s constraint. The question is no longer whether we can work less, but whether we can afford not to rethink how we work at all.
One hundred years ago, Ford shortened the week to make capitalism more efficient. Today, Do More in Four asks whether efficiency has finally outgrown its container. The four-day workweek, in this telling, is not a retreat from ambition. It is an update to it.
