Duty to Bargain Collectively.
Section 13
SEC. 13. Duty to Bargain Collectively.—In the absence of an agreement or other voluntary arrangement providing for a more expeditious manner of collective bargaining, it Shall be the duty of an employer and the representative of his employees to bargain collectively in accordance with the provisions of this Act. Such duty to bargain collectively means the performance of the mutual obligation to meet and confer promptly and expeditiously and in good faith, for the purpose of negotiating an agreement with respect to wages, hours, and/or other terms and conditions of employment, and of executing: a written contract incorporating such agreement if requested by either party, or for the purpose of adjusting any grievances or question arising under such agreement, but such duty does not compel any party to agree to a proposal or to make concession. Where there is in effect a collective bargaining agreement, the duty to bargain collectively shall also mean that neither party shall terminate or modify such agreement, unless it has served a written notice upon the other party of the proposed termination or modification at least thirty days prior to the expiration date of the agreement, or in the absence of an express provision concerning the period of validity of such agreement prior to the time it is intended to have such termination or modification take effect. It shall be the duty of both parties, without resorting to a strike or lockout, to continue in full force and effect all the terms and conditions of the existing agreement during the said period of thirty days.
