N.M. Code R. § 11.1.4.111
When the LRD has information about an alleged violation that affects multiple employees, which the director, in his sole discretion, believes involves a systemic violation of the wage and hour laws of the state of New Mexico by an employer, the director may direct the LRD to undertake a directed investigation. A directed investigation is a workplace-wide investigation into an employer's wage payment practices, which is not limited in scope to the claims of the individual reporting the alleged violation of the law. Among other investigatory methods, a directed investigation may include interviews with individuals having information and obtaining and reviewing all employment records for the time period under investigation. It may also include enforcement action against the employer to collect wages, damages, or penalties owed, based on violations uncovered as to any employee.
