S.C. Code § 8-17-360
Once an appeal has been made to the State Human Resources Director and has been determined to meet all jurisdictional requirements, but before forwarding the appeal to the committee, the State Human Resources Director shall appoint a mediator to the appeal of the following adverse employment actions: terminations, salary decreases based on performance, demotions, suspensions for more than ten days, and reductions in force when the State Human Resources Director determines there is a material issue of fact regarding inconsistent or improper application of the agency's reduction in force plan or policy. The mediator must be an impartial third party who shall act to encourage and facilitate the resolution of the dispute through mediation. The mediator shall review the documents which have been submitted by each party and shall schedule a time to meet with both parties, jointly or independently, to attempt to resolve the matter. Mediation conferences are confidential and limited to the parties and their representatives. Other persons may attend only with the permission of the parties and the mediator. The parties or their representatives attending a mediation conference must have full authority to negotiate and recommend settlement. Failure of the covered employee or the employee's representative to attend a mediation conference without reasonable justification constitutes a waiver of the employee's rights to further pursue the appeal. The State Human Resources Director shall determine whether or not reasonable justification exists based on documents submitted by the parties.
The mediator may not be compelled by subpoena or otherwise to divulge records or discussions or to testify in regard to the mediation in any adversary proceeding or judicial forum. All records, reports, documents, discussions, and other information received by the mediator while serving in that capacity are confidential.
