Any provision of a collective bargaining agreement which is ratified by the School Board and affects collective bargaining members shall prevail over any School Board rule conflicting with the agreement. The School Board rule shall be deemed to be amended during the term of the agreement. If such agreement expires prior to ratification of a subsequent agreement, the provisions of the expired agreement shall be in effect until ratification of a subsequent agreement or approval by the legislative body by a Resolution of Impasse.

Collective bargaining may not preclude a district school board from carrying out its constitutional and statutory duties as defined in F.S. 1012.22.
