While there is no easy way to address concerns about how (and how much) we work, research tells us that no matter what we do, taking a holistic, long-term focus on the well-being of the workforce is the best path to both happiness and prosperity. Maybe the answer is a four-day workweek. Or maybe it’s something else. But we must start with an honest appraisal of how productivity and time trade-offs impact the well-being of workers. Before trying a four-day workweek, employers need to be aware of two important factors. First, a reduction in hours must also be accompanied by a revision of or even reduction in workload. Second, time at work could become even more intense and stressful for workers, even if there are productivity benefits to be had.
