Who could have predicted that people would like a shorter work week?

Utah planners say they have not seen the energy savings they expected when a four-day, 10-hour-a-day schedule was ordered for state employees, but there has been another benefit: an uptick in productivity and worker satisfaction. Though some don't like the longer days, seventy percent of Utah state employees prefer the shorter work week. Not only that but, good for their employer, they are taking less leave and working less overtime.
