Which term best describes an individual who has been consuming alcohol at work?

The term that best describes an individual who has been consuming alcohol at work is "not permitted on the job." This is because consuming alcohol in a workplace setting is typically against policy in most organizations due to the safety risks and impairment it causes. Alcohol consumption can significantly affect an individual's ability to perform their job duties safely and effectively, making them a risk not only to themselves but also to their coworkers.

The terminology around safe work environments emphasizes accountability and maintaining a professional standard, which includes being fit for duty. When alcohol is involved, it undermines that ability, leading to policies that prohibit such behavior. Therefore, a person who has been drinking on the job is not only likely to be in violation of workplace safety policies, but they are also typically sent home or reassigned until they are sober and can return safely to their duties.
