Do More in Four: Why It's Time for a Shorter Workweek

An impassioned—and data-driven—case for a four-day workweek.

The five-day workweek is a pillar of modern life, but it isn't backed by science, ancient wisdom, or divine decree. It's simply a relic of the industrial age—and it's time for an upgrade. What if we could accomplish more while working fewer days?

A shortened workweek once seemed like a radical idea. Today, it's embraced by innovative business leaders, forward-thinking politicians, and a new generation of workers demanding more meaningful work.

In Do More in Four, Joe O'Connor, a pioneer in designing and leading four-day-workweek pilots around the globe, and journalist Jared Lindzon, whose work has appeared in the New York Times, Fortune, and TIME magazine, present a groundbreaking, data-driven exploration of why a four-day workweek isn't merely possible—it's necessary in the age of artificial intelligence.

O'Connor and Lindzon draw on extensive research, compelling case studies, and personal interviews with experts—including a Nobel Prize–winning economist and Bill Gates—to reveal how organizations are reimagining work. From a consumer products giant in New Zealand to a global nonprofit, a Canadian law firm, and a Midwestern architecture firm, they take readers inside the companies transforming their work models to improve employee outcomes while driving revenue growth.

Do More in Four offers a battle-tested blueprint for a smarter, more humane approach to work.
