For the past year, all government employees in Utah have had a four-day workweek. The results of the trial run are in, and they look good: the state says it saved $1.8 million in electrical bills, eliminating 6,000 metric tons of carbon dioxide, while 82 percent of workers say they like the new scheme. One possible downside of the new schedule, reports Scientific American, is that it may encourage eating more fast food, as workers put in 10-hour days to make up for the lost Friday.
