Employees don't need to be addicted to alcohol to cost companies money. Light and moderate drinkers cause 60 percent of alcohol-related incidents of absenteeism, tardiness and poor quality of work, while dependent drinkers cause 40 percent. The primary business costs of problem drinking are from the treatment of alcohol-related injuries and health conditions, lost time from work and reduced productivity. For example, employees are nearly two times more likely to call in sick the day after drinking heavily than on other days. These costs could be decreased if substance abuse treatment, which is highly cost-effective, were more available.
