Today, more than 34 million US adults telecommute at least occasionally. Fueled by broadband adoption, better collaboration tools, and growing management experience, the US telecommuting ranks will swell to 63 million by 2016. Those 29 million new telecommuters lined up five abreast would stretch from New York to LA! Leading the surge are occasional telecommuters and regular telecommuters who work from home between one and four days a week. The impact of this expanding remote workforce is far-reaching: It will force firms to expand their digital footprints, harness new social software, crisply define their culture, and examine their real estate and energy policies.
