S.D. Codified Laws § 3-6C-21
A permanent employee who is a certified disaster service volunteer of the American Red Cross may be granted leave from work with pay not to exceed ten days in any one calendar year to participate in disaster relief services for the American Red Cross during a State of South Dakota declared disaster, upon the request of the American Red Cross for the services of the employee and upon approval of that employee's appointing authority. However, an employee who is needed by the employee's appointing authority to perform job-related disaster services may not be granted this leave. The appointing authority shall compensate an employee granted leave under this section at the employee's regular rate of pay for regular work hours during which the employee is absent from work.
