Impairment (also known as unfit for duty/work) resulting from alcohol use can have severe consequences for not only the impaired worker, but also their co-workers, supervisor, and employer.

Employers must ensure that all of their employees are able to perform work safely. Impairment in the workplace due to alcohol consumption is a hazard that employers need to manage through policy and procedures.

The term impairment refers to a variety of conditions and/or substances that impact a worker’s normal ability to work safely. Impairment can come from fatigue, stress, illness, or the use of alcohol, illicit drugs, prescribed and over-the-counter medication.
