S.C. Code Ann. § 8-11-120
In addition to any other requirement provided by law, when a job vacancy occurs in any state office, agency, department, or other division of the executive branch of state government, the appointing authority must post a notice with the Office of Human Resources of the State Budget and Control Board and the South Carolina Employment Security Commission at least five working days before employing a person to fill the vacancy. The posting must give notice of the job vacancy, describe the duties to be performed by a person employed in that position, and include any other information required by law.
For purposes of this section, "appointing authority" shall have the same meaning as in Section 8-11-220.
