It is the public policy of the State of Illinois to grant public employees full freedom of association, self-organization, and designation of representatives of their own choosing for the purpose of negotiating wages, hours and other conditions of employment or other mutual aid or protection.
It is the purpose of this Act to regulate labor relations between public employers and employees, including the designation of employee representatives, negotiation of wages, hours and other conditions of employment, and resolution of disputes arising under collective bargaining agreements.
It is the purpose of this Act to prescribe the legitimate rights of both public employees and public employers, to protect the public health and safety of the citizens of Illinois, and to provide peaceful and orderly procedures for protection of the rights of all. To prevent labor strife and to protect the public health and safety of the citizens of Illinois, all collective bargaining disputes involving persons designated by the Board as performing essential services and those persons defined herein as security employees shall be submitted to impartial arbitrators, who shall be authorized to issue awards in order to resolve such disputes. It is the public policy of the State of Illinois that where the right of employees to strike is prohibited by law, it is necessary to afford an alternate, expeditious, equitable and effective procedure for the resolution of labor disputes subject to approval procedures mandated by this Act. To that end, the provisions for such awards shall be liberally construed.
