　　One-quarter of the U.S. work force could be doing their jobs from home if all those able to telecommute chose to do so, and all those people working from home could translate into annual gasoline savings of $3.9 billion, according to the National Technology Readiness Survey. However, many still select to work at the office. The study found that 2 percent of U.S. workers telecommute full-time and another 9 percent do so part-time. But another 14 percent of workers have the option of telecommuting, or have jobs conductive to the practice but choose not to. “The numbers suggest that many people would rather work at the office even if their job allowed telecommuting,” said Professor P.K. Kannan, of the Robert H. Smith School of Business at the University of Maryland. “That seems to suggest that even if employers were to say tomorrow that everybody had the option of telecommuting and you would save a lot of gas, that’s not going to happen. An hypothesis could be that people still need the ‘face time’ with their bosses. Another thing is people miss the social interaction, just being at home.” And with a median one-way commute of 10 miles and a median one-way commute time of 20 minutes, the daily trip for many workers is not that bad, he added. Of those who can already telecommute, most do so only one, two or three days per week, the study found.
