More Americans than ever are staying connected to the office while away this holiday season, but not all are complaining about it, according to a survey released Dec. 12 that was commissioned by Lexmark. Surveyed “knowledge workers”–defined as individuals who use a computer at work for word processing, database, spreadsheet, Internet or email applications–say that they are more stressed at work than they were a few years ago, but they blame longer hours and not wireless technology. Though 61 percent of workers are committed to a 40-hour workweek, the majority said they work at least five hours more each week, with 10 percent reporting working an additional 20 hours weekly.
