China’s largest travel agency Ctrip recently did a fascinating experiment. The company’s leaders had half their employees work from home for nine months, and the other half work only from the office. The results? Those who worked from home had a 13 percent improvement in performance from people working at the office. They found that people at home actually work their full shift whereas those at the office might be delayed by traffic or may take a long lunch break. Those working at home were also able to concentrate better away from the office. For firms, having employees work at home boosts profit. For society, there’s a huge reduction in congestion, commuting times, and ultimately, pollution.
