Network configuration taking longer than you imagined? Go ahead, turn the air blue. That's the advice of Yehuda Baruch, a professor at England's University of East Anglia, who led a study on the use of profanity in the workplace. Swearing can ease stress and boost team spirit, according to Baruch's study. He said the researchers found that "swearing was used as a social phenomenon to reflect solidarity and enhance group cohesiveness, or as a psychological phenomenon to release stress." Baruch does emphasize, however, that workers should not swear in a "negative, abusive manner," and it's best to clean up your language around customers and managers.
