When a trade union or employers’ organisation that is representative within the scope of the agreement adheres to all the clauses of a branch agreement or a professional or inter-professional agreement, this organisation has the same rights and obligations as the signatory parties.
In particular, it may sit on joint bodies and participate in the management of institutions created by the branch agreement or the professional or cross-industry agreement, as well as take part in negotiations concerning the amendment or revision of the text in question.
