S.C. Code Ann. § 41-27-525

If the majority of the weeks of work in an individual's base period includes part-time work, the individual shall not be denied unemployment benefits under any provisions of this act relating to availability for work, active search for work, or failure to accept work, solely because the individual is seeking only part-time work. The phrase "seeking only part-time work", as used in this subsection, means the individual claiming unemployment benefits is available for a number of hours per week that are comparable to the individual's part-time work experience in the base period.
