(A) If an employee of a local school district makes a written request for a leave to be employed at a charter school, the school district shall grant the leave for up to five years as requested by the employee. The school district may require that the request for leave or extension of leave be made by the date provided for by state law for the return of teachers' contracts. Employees may return to employment with the local school district at its option with the same teaching or administrative contract status as when they left but without assurance as to the school or supplemental position to which they may be assigned.
(B) During a leave, the employee may continue to accrue benefits and credits in the South Carolina Retirement System by paying the employee contributions based upon the annual salary of the employee, and the charter school shall pay the employer contribution. The South Carolina Retirement System may impose reasonable requirements to administer this section.
(C) The provisions of this section do not apply to teachers and other employees of a converted school whose employment relation is governed by Section 59-40-100(C).
