One of the largest pilot programs to disrupt the world of work as we know it is underway in the UK. The four-day workweek is growing in popularity, and in most instances, it has been successful where it’s been applied. “There are many people who are spending more time at the office than they need to,” says Juliet Schor, an economist and sociology professor at Boston College. Schor is the author of the book The Overworked American and leads research at 4 Day Week Global.
