The Four-Day Formula : Dale's Vision for Modern Work Culture For Better Health, Dr. Dale Whelehan, Founder @ Four Day Work Week

In this episode I had the opportunity to interview a fascinating behavioral scientist and former CEO of Four Day Week Global about the concept of reduced working hours- Dr. Dale Whelehan. He explained how his interest in this field began when observing surgeons suffering from impaired decision-making and emotional regulation due to excessive working hours. What struck me most was his insight that today's workforce has fundamentally changed since the five-day workweek was introduced – we've shifted from physical, repetitive labor to highly cognitive work, yet human attention spans remain limited to about 3.5 hours of optimal performance daily. He emphasized that a four-day workweek isn't merely about cutting hours but redesigning work to eliminate unproductive time, with pilot studies across multiple countries showing reduced stress, better recovery, increased productivity, and improved business outcomes.

During our conversation, I was particularly moved by his observations about the broader personal and societal impacts of reduced working time. People report sleeping more, exercising more, and having greater time for family, friends, and community engagement. Women especially report higher levels of wellbeing, helping close persistent gender gaps. He shared a compelling perspective on how work has become a "de facto religion" in our society as we worship productivity at the expense of human connection. When I asked about the future of healthcare, his response was thought-provoking: AI will transform knowledge requirements for healthcare professionals, creating an opportunity to refocus on interpersonal connections and compassionate care. He cautioned that we must address systemic issues of recruitment and retention rather than simply attracting healthcare workers from countries that need them most – a perspective that left me contemplating the global ethics of our current healthcare systems.
