means A person who compulsively works excessively, often at the expense of health, relationships, or leisure, and feels uneasy when not working.

from A blend coined in the late 1960s by psychologist Wayne Oates, who grafted '-aholic' from 'alcoholic' onto 'work,' deliberately framing overwork as an addiction with its own compulsions and withdrawal symptoms. The '-aholic' suffix later became a reusable joke-template for any compulsion (shopaholic, chocoholic), but workaholic was the original transplant.
