Ind. Code § 22-9-2-6
Every person shall keep true and accurate records of the ages of all persons employed by the person as reported by each employee, and shall upon demand furnish to the commissioner of labor, or to the authorized representative of the commissioner of labor, a true copy of any such record, verified upon oath. Such record shall be open to investigation by the commissioner at any reasonable time. If on all the testimony taken, the commissioner of labor shall make a preliminary determination that the employer has engaged in or is engaging in unfair employment practices, the commissioner shall endeavor to eliminate such unfair employment practices by informal methods of conference, conciliation and persuasion. If voluntary compliance cannot be obtained, the commissioner of labor shall be empowered to issue a complaint stating the charges and giving not less than ten (10) days' notice of hearing before the commissioner of labor at a place fixed in the notice. Any complaint issued pursuant to this section must be so issued within four (4) months after the alleged unfair employment practices were committed. The respondent shall have the right to file an answer to such complaint and may appear at such hearing with or without counsel to present evidence and to examine and cross-examine witnesses. Upon the completion of testimony at such hearing, if determination is made that unfair practices were committed, the commissioner of labor shall state the commissioner's findings of fact and, if satisfied therewith, may issue the commissioner's finding that the employer has ceased to engage in unfair employment practices.
