Yes, but that doesnt mean an employer has to put up with an employees drinking. The disease of alcoholism meets the definition of a disability, which means that an employer may not make job decisions based on the fact that an employee is an alcoholic, attends AA meetings, or takes medication to curb the urge to drink. However, an employer may prohibit drinking at work and may generally hold all employees to the same standards of performance and conduct. An employee who cant meet those standards because of drinking may be disciplined and ultimately terminated, even if the employee is an alcoholic.
