Despite strong evidence to the contrary on television sitcoms and in USA Today, a Northwestern University report released Monday claims that some Americans do not work in office settings. 'The non-office-employed worker, long thought to be a fanciful creation from the realm of business fiction, may actually exist and walk among us,' said Tim Irving, professor at Northwestern's Kellogg Business School. 'Many offices, for instance, receive materials from outside, such as mail and food. While these items are undoubtedly produced in other offices, the people who bring them from one office to another do not necessarily appear to have an office of their own.' It has been further theorized that, given the existence of jobs outside offices, workers may exist who do not wear business suits.
