A DUI/DWI conviction will appear on a criminal background check requested by a prospective employer and may adversely affect employment opportunities in some professions, industries, and occupations—especially jobs (1) for which a commercial driver’s license (CDL) is required, (2) for which a person must operate heavy equipment or machinery, or (3) in which a person is entrusted with ensuring the safety of others (air traffic controller, police officer) or safeguarding sensitive information or data. Generally, the only way to remove a DUI/DWI conviction from appearing in some or all of such background checks is to have it expunged or sealed—which is only possible in limited circumstances.

In states in which employment is at-will an employer may terminate an employee for a DUI/DWI arrest or conviction. If the employee has a written employment contract there may be limitations on the grounds on which the employee may be terminated, and a DUI/DWI arrest or conviction may fall within those grounds of termination for cause—in other words, termination for an identified reason, and not for no reason, which is permissible under employment at will.

In Oregon, a DUI (Driving Under the Influence) or DWI (Driving While Intoxicated) conviction will indeed appear on a criminal background check. This can negatively impact employment prospects, particularly for positions that require a commercial driver's license (CDL), involve operating heavy machinery, or entail responsibility for public safety or sensitive information. Oregon law allows for the expungement of certain criminal records, including DUI convictions, under specific conditions, such as the passage of time and the absence of subsequent convictions. However, expungement is not guaranteed and is subject to court approval. Regarding employment, Oregon is an at-will employment state, meaning employers can terminate employees for any lawful reason, including a DUI/DWI arrest or conviction, unless there is a written employment contract that specifies the conditions under which termination is permissible. In such cases, a DUI/DWI could be considered a 'for cause' reason for termination if it is specified in the contract.
