The essence of the SA Reserve Police Service system is that of a voluntary service. The tariffs at which reservists are compensated when called for duty are based on a sliding scale depending on a rank level per eight-hour shift. Constables are paid R128,72; sergeants are paid R162,88; inspectors are paid R206,09; captains are paid R260,77; superintendents are paid R329,96; and senior superintendents are paid R451,62. Thank you.
