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 Louisiana (LA), a DUI/DWI conviction can indeed appear on a criminal background check and may negatively impact employment prospects, particularly in fields that require a commercial driver's license (CDL), the operation of heavy machinery, or roles responsible for public safety or sensitive information. Louisiana law allows for the expungement of a DUI/DWI conviction under certain conditions, which can remove the conviction from public view on background checks. However, expungement is not guaranteed and depends on meeting specific criteria and the passage of time since the conviction. Regarding employment, Louisiana is an at-will employment state, meaning employers can terminate employees for any legal reason, including a DUI/DWI arrest or conviction, unless there is a written employment contract that specifies the conditions under which termination is allowed. In such cases, a DUI/DWI could be considered a 'for cause' reason for termination if it is specified in the contract.
