S.C. Code § 41-15-520
A private sector employee believing that he has been discharged or otherwise discriminated against by any person in violation of Section 41-15-510 may, within thirty days after the violation occurs, file a complaint with the Director of the Department of Labor, Licensing and Regulation alleging the discrimination. Upon receipt of the complaint, the director shall within fifteen days forward the complaints that allege violations of Section 41-15-510 and violations of a federal statute other than 29 U.S.C.A. Section 660(c) to the United States Department of Labor Whistleblower Program. For other complaints, the director shall cause an investigation to be made as he deems appropriate. If upon such investigation the director determines the provisions of Section 41-15-510 have been violated, he shall institute an action in the appropriate court of common pleas against such person. In any such action the court of common pleas shall have jurisdiction for cause shown to restrain violations of Section 41-15-510 and order all appropriate relief including rehiring or reinstatement of the employee to his former position with back pay. A public sector employee believing that he has been discharged or otherwise discriminated against by any person in violation of Section 41-15-510 may proceed with a civil action pursuant to the provisions contained in Chapter 27, Title 8.
