    Collective agreements made compulsory by Royal Decree (i.e. sanctioned under criminal law) 

    In case of posting of workers in Belgium, only the collective agreements that have been made compulsory by Royal Decree (i.e. sanctioned under criminal law) must be applied.

    The provisions of collective agreements made compulsory by Royal Decree are concluded under the Act on collective agreements of 5 December 1968 (with regard, inter alia, to wage/salary scales). 

    Such collective agreements made compulsory by Royal Decree  have either a national scope either a sectorial scope.

    1. National collective agreements are adopted by the National Labour Council and apply to the whole private sector.

      A consolidated version of such national collective agreements can be found by using the following links : in French language  : and in Dutch language :
    2. Sectorial collective agreements are concluded within joint committees and apply to a branch of economic activities.

    Which collective agreements made compulsary by Royal Decree are applicable in the sector which is concerned by posting depends on the principal activity of the company concerned, as carried out during the posting in Belgium. 

    This principal activity indicates under which joint committee the company concerned falls, which in turn determines which sectorial collective agreements are applicable.
