Liquor can be sold by persons 18 to 20 years of age only in licensed establishments where selling or serving the intoxicating liquor is part of the minor's employment, and where there is proper supervision of these minor employees to ensure that the minors shall not consume the intoxicating liquor.

Persons under 21 years of age employed to sell or dispense malt, vinous, or spirituous liquors are required to be supervised by another person who is on premise and has attained 21 years of age.

Disorderly Premises If you are an on-premises licensee, you must not allow your establishment to become disorderly. Disorder includes fights, disturbances, the use or sale of controlled substances, prostitution, lewd and indecent conduct and excessive noise.

Of course, this means you must be at least 18 years of age. So as long as you are 18 or older, you can work as a bartender, server, or cashier in the state of Oregon.

Tied House Laws These restrictions are commonly known as the "tied house" laws. Licensed manufacturers and wholesalers are prohibited from having any interest, direct or indirect, in any premises where alcoholic beverages are sold at retail.

Working in a restaurant or bar under 18 You can serve alcohol in a restaurant if you're 16 or 17 as long as the licence holder or bar manager has approved the sale. You may be restricted to selling alcohol in sealed containers (such as cans or bottles) in some areas.

Applicants must be at least 18 years old and pass an in-person or online alcohol server education course certified by the OLCC. Oregon was the first state in the country to require all alcohol servers to be trained.
