The five-day rotating workweek was adopted by Henry Ford in 1926, marking the 100th anniversary of the adoption of the five-hour workweek. The authors argue that this shift in work hours was influenced by the Industrial Revolution, a period of rapid economic and technological change. They suggest that by reducing the workweek to four days, organizations can foster well-being and work-life balance, which drives innovative thinking and give workers a reason to embrace new AI tools. They also suggest that AI is already changing how we work, and the types of skills that deliver value. The article also notes that the number of hours worked is less relevant than the quality of those worked hours from 1948.
