The author attempts to answer whether the Polish labour law permits to terminate a part of a collective bargaining agreement. The provisions of Chapter XI of the Labour
Code provide for the possibility of amending the collective bargaining agreement only by an additional protocol concluded by both parties. According to the labour law jurisprudence so-called partial termination of the collective bargaining agreement is possible. This view is supported by referring to the provisions of Section XI of the Labour Code regulating the rules of termination of collective bargaining agreements and by the claim that the right of each party to terminate the agreement in its entirety includes the right to unilaterally terminate a part of the agreement, i.e. some of its provisions. A maiori ad minus inference is invoked
to support this position. The author formulates a thesis that none of the parties is entitled to terminate certain provisions of the agreement. This thesis is based on the detailed analysis of the provisions regulating the amendment, termination, and suspension of the collective
bargaining agreement as well as the Supreme Court’s case law. A party to a collective bargaining agreement that receives a partial termination of the collective bargaining agreement is not entitled to appeal to the labour court against the termination. Neither is a party to a collective agreement entitled to lodge a claim for unjustified termination of a part of the collective bargaining agreement.
