According to the American Community Survey, tele-commuting jumped 79 percent between 2005 and 2012. More than 9 million American workers did their jobs exclusively from home in 2010, according to the U.S. Census, and 30 million work from home at least once a week. And TechCast at George Washington University estimates as many as 30 percent of U.S. private sector workers could be working from home by 2019. For sales professionals, that proportion is certainly higher. The Telework Research Network found in 2011 that 70 percent of those working from home are in management, professional, sales and office jobs. If you’re in sales, you probably spend a considerable amount of time on the go. And why shouldn’t you? Smartphones offer constant, pocket-sized connectivity. Ubiquitous Wifi threatens to render the cubicle obsolete, and the right social networking strategy can sup-plant a hundred individual pitch meetings.
