Section 34-12-04 - Collective bargaining1. For the purposes of this chapter, to bargain collectively means the performance of the mutual obligations of the employer and the representative of the employees to meet at reasonable times and confer in good faith with respect to wages, hours, and other terms and conditions of employment, or the negotiation or renegotiation of an agreement, or any question thereunder, and the execution of a written contract incorporating any agreement reached if requested by either party, but such obligation does not compel either party to agree to a proposal or require the making of a concession.2. When there is in effect a collective bargaining contract, the duty to bargain also means that no party to such contract may terminate or modify such contract at the conclusion of its term until sixty days after either party mails notice of a desire to terminate or to modify. A strike or lockout for economic purposes is unlawful until the end of the sixty-day period. The duty to bargain collectively continues despite termination of a collective bargaining contract unless the employee bargaining representative has lost its majority status.
