In praise of boundaries. A conversation with Miss Manners. Interview by Diane L. Coutu

The past three decades have been a time of increasing informality in the American workplace. It's easy to characterize this growing comfort with the casual as a positive step for workplace culture, an outgrowth of the American democratic belief in workers' equality. Informal environments are said to be more trusting and open, and workers who are free to express their personalities are more comfortable and thus more creative--right? According to etiquette guru Judith Martin--known far and wide as Miss Manners--informality in the workplace may do more harm than good. Without some formality in social intercourse, Miss Manners argues, human interactions end up being governed by laws, which are too heavy-handed to serve as a guide through the nuances of personal--or professional--behavior. Since our earliest beginnings, we have developed formal rules to accompany shared human experiences, such as eating and mourning. Yet, says Miss Manners, something in us rebels against form and etiquette, and every so often, an anti-manners movement takes hold, and people come to believe that following etiquette is unnatural. One recent such movement has led to the belief that a distinction between our work life and our professional life is unnecessary. If we hope to reassure our customers that we are indeed professional, however, we need to be aware of the boundaries of professional behavior. On the whole, Miss Manners argues, informality in the workplace leads to a host of problems, from making employees feel pressured to "socialize" with coworkers during weekends and evenings to sexual harassment. Despite the shortcomings of informality in the American workplace, though, Miss Manners believes that we have the best code of manners the world has ever seen-in theory. In practice, American etiquette is undoubtedly still a work in progress.
