Trade unions, in general, considered that it is possible and fully in line with the competences of the Member States to apply the provisions provided in the Directive also to other categories of workers who are not considered as posted according to the Posting of Workers Directive.
Sindikati su općenito smatrali da je moguće i sasvim u skladu s nadležnostima država članica primjenjivati odredbe predviđene Direktivom i na druge kategorije radnika koji se na temelju Direktive o upućivanju radnika ne smatraju upućenim radnicima.
