The Legislature finds that the Bureau for Social Services is having extreme difficulty retaining child protective service workers, youth service workers, adult protective service workers, and other related workers, including necessary casework support personnel and managers at the county level, who assist in the provision of services to vulnerable populations. To retain qualified employees in these crucial positions, there is no requirement for uniformity regarding the pay scale for the same classification between regions of the state to account for market rates and demand for specific positions. The provisions of § 6C-2-1 et seq. of this code shall be applicable to the employees of the merit-based system as set forth in § 49-10-102 of this code, however, there is no right to a grievance for any such regional pay disparity for the same job classification.
