Louisiana Revised Statutes Tit. 29, § 404. Discrimination prohibited

A. A person who is a member of, applies to be a member of, performs, has performed, applies to perform, or has an obligation to perform service in a uniformed service shall not be denied initial employment, reemployment, retention in employment, promotion, or any benefit of employment by an employer on the basis of that membership, application for membership, performance of service, application for service, or obligation.

B. An employer shall be considered to have denied a person initial employment, reemployment, retention in employment, promotion, or a benefit of employment in violation of this Section if the person's membership, application for membership, service, application for service, or obligation for service in the uniformed services is a motivating factor in the employer's action, unless the employer can prove that the action would have been taken in the absence of such membership, application for membership, performance of service, application for service, or obligation.

C. An employer may not discriminate in employment against or take an adverse employment action against any person because such person has taken an action to endorse a protection afforded any person under this Part, has testified or otherwise made statement in or in connection with any proceeding under this Part, has assisted or otherwise participated in an investigation under this Part, or has exercised a right provided for in this Part. The prohibition provided for in this Subsection shall apply with respect to a person regardless of whether that person has performed service in the uniformed services and shall apply to any position of employment, including a position that is for a brief, nonrecurrent period and there is no reasonable expectation that such employment will continue indefinitely or for a significant period.
