The 4-Day Workweek: Why the Business Case Doesn't Hold Up and Won't Anytime Soon

April 29, 2026: Bill Gates is predicting a 2-day workweek. Jamie Dimon says 3.5. Eric Yuan, the CEO of Zoom, says 5 days is over. Fortune just amplified a major study claiming we waste a full day every week procrastinating. The 4-day workweek movement has never had more wind at its back. In this episode, I'm making the bulletproof business case against it. I'll walk through eight reasons the case doesn't hold up — and why the policy isn't likely to spread broadly anytime soon, even with all the keynote energy behind it. I'm covering the studies that don't measure what they claim to measure, the Iceland myth, the company failures that get scrubbed from the data, the AI rhetorical pivot, why the happiness data isn't actually a business case, the wage math nobody talks about, the competitive reality at the country and company level, and why even the countries running pilots are voting against legislating it.
