The compensation and employer contributions of any new personnel employed for the purpose of implementing specific provisions of the South Carolina Education Improvement Act of 1984 must be paid from funds appropriated for that purpose by the General Assembly from funds derived from increased revenue provided for in the Education Improvement Act of 1984 Fund. This may not be construed to preclude any school district from providing additional compensation and employee contributions for the purpose of implementing specific provisions of the South Carolina Education Improvement Act of 1984. School district employees are not entitled to receive any across-the-board pay increases or employer contributions provided for other state employees in the annual general appropriation act unless otherwise authorized by the General Assembly in that act.
