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.
