It is the public policy of this State and the purpose of this Act to promote orderly and constructive relationships between all educational employees and their employers. Unresolved disputes between the educational employees and their employers are injurious to the public, and the General Assembly is therefore aware that adequate means must be established for minimizing them and providing for their resolution. It is the purpose of this Act to regulate labor relations between educational employers and educational employees, including the designation of educational employee representatives, negotiation of wages, hours and other conditions of employment and resolution of disputes arising under collective bargaining agreements. The General Assembly recognizes that substantial differences exist between educational employees and other public employees as a result of the uniqueness of the educational work calendar and educational work duties and the traditional and historical patterns of collective bargaining between educational employers and educational employees and that such differences demand statutory regulation of collective bargaining between educational employers and educational employees in a manner that recognizes these differences. Recognizing that harmonious relationships are required between educational employees and their employers, the General Assembly has determined that the overall policy may best be accomplished by (a) granting to educational employees the right to organize and choose freely their representatives; (b) requiring educational employers to negotiate and bargain with employee organizations representing educational employees and to enter into written agreements evidencing the result of such bargaining; and (c) establishing procedures to provide for the protection of the rights of the educational employee, the educational employer and the public.
