A new study shows that workplace cultures affect the incidence of alcoholism in workers. Specifically, the study found that workers in workplaces that discouraged the use of alcohol had a 45 percent lower chance of being a heavy drinker than among employees who did not. The report suggests that drinking is a cultural norm rather than a knowledge issue; therefore, employers who are concerned about worker alcohol use should actively discourage drinking at lunch, enforce rules about drinking at work and exercise discretion in the use of alcohol at both business affairs and routine informal get-togethers. (Source: Journal of Occupational and Environmental Medicine.)
