Four-Day Workweek: The Economic Case, the Pilot Data, and the Roadmap for Getting There

What if the five-day week was never actually correct - just inherited?

The Four-Day Workweek makes the structural case for one of the most contested ideas in modern work: that a meaningful share of the standard week never converts into real output, and that organizations willing to find out where their own slack lives can reclaim a full day without losing a thing.

Drawing on the UK's landmark national trial, Iceland's multi-year public-sector program, and the pilots that didn't hold up to scrutiny, this book treats the four-day week as a claim worth testing - not a lifestyle trend to embrace on faith.

Inside, you'll find:

• 
  
• The economic and psychological research behind why a standard week contains reclaimable slack
• 
  
• An honest, sourced breakdown of every major pilot program - including where the headline statistics don't hold up
• 
  
• A clear map of which industries the model fits today, and which need real structural adaptation first
• 
  
• The strongest objections to the four-day week, taken seriously rather than dismissed
• 
  
• Three practical playbooks: for the employee negotiating their own arrangement, the manager running a real pilot, and the company planning a full rollout
