Alcoholism is a disability under the Americans with Disabilities Act. The EEOC notes here that the ADA may protect a “qualified” alcoholic who can meet the definition of “disability.” What is a “qualified” alcoholic? Someone who can perform the essential functions of the job with or without accommodation.
Allowing an alcoholic to attend AA to remain clean and sober? That works.
But, accommodating an alcoholic who “falls off the wagon,” gets a DUI, and needs time off from work because he is incarcerated? Not so much.
