Content Collective agreements can in principle deal with all matters relating to the collective autonomy of the social partners. However, there are a number of exceptions to this principle. On the one hand, the law establishes a positive delimitation of the content of the agreements. Article 5 of the Collective Relations Act stipulates that they may regulate the reciprocal rights and obligations of workers and employers; the relationship between the signatory parties to an agreement; and procedures for the settlement of disputes arising from individual contracts of employment, the introduction of conciliation, mediation and arbitration procedures. This formulation reflects the distinction made by lawyers between the mandatory and normative parts of collective agreements. In addition, the law (in particular in Article 6) contains a negative delimitation of the content of the agreements.
