Even as gas prices hit historic highs in the United States, most residents can't telecommute, according to a new survey released by advocacy group Telework Exchange.

Nearly all of the respondents in a recent survey by Telework Exchange expressed an interest in telecommuting and 92% said they believed their jobs could be done from home. But only 39% of the respondents, culled from 377 registrants of the Telework Exchange Web site, said they were able to telework at least part time.

"Telework Exchange registrants (both government and private-sector employees) do have a clear interest in telework," Cindy Auten, Telework Exchange's general manager, said in an e-mail. "We find that this is an accurate sample of the full population."

Even with people in much of the United States paying $4 a gallon or more for gas, telecommuting seems to be facing an uphill battle. Telework Exchange has pushed for more telework options for U.S. government workers, but a survey released in March by CDW-G found only 17% of federal employees telecommuting.

Surveys have shown that management resistance to telework remains a barrier, Auten said. "What we found was that as managers become exposed to/involved in telework, their approval of the operating practice improves significantly," she added. "Encouraging managers to telework is a critical step to achieving overall agency telework adoption. Further, agencies must educate and train management on telework drivers and benefits."

Thirty-eight percent of the survey's respondents said they they're willing to pay any amount for gas. More than eight in 10 respondents said they rely on their vehicles to get to work, with only 13% using car pooling and 10% using public transportation.

However, 78% of survey respondents said they were making lifestyle changes because of high gas prices. More than seven in 10 said they were limiting car trips or consolidating errands. Another 62% said they were spending less in general on other things and 53% said they were eating out less often.

An average U.S. resident spends $2,052 a year for gas to commute, and spends 264 hours on the road, according to the survey.

"We are seeing a tipping point for people to start looking for other alternatives to commuting," Auten said.
