The technologist and writer Kevin Kelly has argued that studies have consistently shown that productivity improves as the numbers of work hours per week decrease, and that this pattern is so strong that it is unlikely that we will reach a point of diminishing returns with regard to working less. So maybe a four-day week is the way to go. There are certainly challenges to making one work—including managing clients' expectations and ensuring that vital tasks are completed on time—but perhaps it’s time to start experimenting.
Technologist and writer Kevin Kelly argues that reducing work hours consistently results in increased productivity. This pattern holds so strongly that there is unlikely to be a point of diminishing returns when working less. Therefore, it may be beneficial to implement a four-day workweek. While challenges such as managing clients' expectations and meeting deadlines must be considered, experimenting with a shorter workweek may be worth considering.
