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 Ohio, a DUI/DWI (known as OVI - Operating a Vehicle under the Influence) conviction will indeed appear on a criminal background check, which can negatively impact employment prospects, particularly in fields that require driving, operating heavy machinery, or positions of trust and safety. Ohio law allows for the expungement or sealing of certain criminal records, but this is subject to eligibility criteria, such as the nature of the offense and the individual's criminal history. Regarding employment, Ohio is an at-will employment state, meaning employers can terminate employees for any legal reason, including a DUI/OVI arrest or conviction, unless there is a written employment contract that specifies the conditions under which termination is allowed. In such cases, a DUI/OVI could be considered a 'for cause' reason for termination if it is specified in the contract.
