Study: Work overflowing into home hours SUNNYVALE, Calif., July 9 (UPI) -- The average American puts in more than a month and a half of overtime a year just by making work calls and answering work e-mails from home, a survey found. In a survey of U.S. working adults initiated by Good Technology, more than 80 percent said they worked outside the office for an average of 7 extra hours each week, or almost another full day of work. Almost half said they felt they had no choice because their work demanded it. Thirty-one percent said they kept working once home as they found it hard to "switch off." Half of Americans can't even put their phone down while in bed, as they read or respond to work e-mails after climbing under the covers, the survey found. "In today's 'always on' mobile environment, secure access to corporate e-mail and apps is a 'must have' versus a 'nice to have' for nearly all companies," said John Herrera, Good Technology vice president of corporate strategy. The survey of 1,000 U.S. adults was conducted May 18-28 by OnePoll on behalf of Good Technology.
