Except as otherwise provided in this section, the term of a collective bargaining agreement must begin on July 1 of an odd-numbered year and must end on June 30 of the next odd-numbered year. If the parties cannot agree to a new collective bargaining agreement before the end of the term of a collective bargaining agreement, the terms of that collective bargaining agreement remain in effect until a new collective bargaining agreement takes effect.
