The term “moonlighting” refers to a person who works a primary job but also works a secondary job on the side. People traditionally moonlight to earn extra money.

For example, a person who is a teacher during the day and works as a cook at night is considered to be moonlighting as a chef. Although many people moonlight to make extra money, others do it to sharpen their skills in another field of expertise or even to fight boredom. The biggest drawback associated with moonlighting is fatigue or getting burned out from working too much.

The health care industry often looks for moonlighters because they need people to work late shifts. People who moonlight in the health care industry make scheduling easier for hospitals and clinics by helping them keep their regular employees happier with better shifts.
