NEW YORK---One in five U.S. workers regularly attends after-work drinks with coworkers, where the most common mishaps range from badmouthing another worker to drinking too much, according to a study released on Tuesday. Most workers attend so-called happy hours to bond with colleagues, although 15 percent go to hear the latest office gossip and 13 percent go because they feel necessary, said the survey conducted for CareerBuilder. com, an online job site. As to what happens when the after-work drinks flow, 16 percent reported bad-mouthing a colleague, 10 percent shared a secret about a colleague and 8 percent said they drank too much and acted unprofessionally. Five percent said they had shared a secret about the company, and 4 percent confessed to singing karaoke. While 21 percent of those who attended said happy hours were good for networking, 85 percent said attending had not helped them get closer to someone higher up or get a better position. An equal number of men and women said they attended happy hours with co-workers, with younger workers aged 25 to 34 most likely and workers over 55 least likely to attend. Overall, 21 percent of workers attend happy hours with co-workers and of those nearly a quarter go at least once a month.
