Det følger af de ovenstående betragtninger, at under hensyn til såvel formålet med direktiv 93/104 som dets opbygning, udgør en årlig betalt ferie af mindst tre ugers varighed i den overgangsperiode, der er fastsat i artikel 18, stk.
It follows that, with regard to both the objective of Directive 93/104 and to its scheme, paid annual leave of a minimum duration of three weeks during the transitional period provided for in Article 18(l)(b)(ii) and four weeks after the expiry of that period constitutes a social right directly conferred by that directive on every worker as the minimum requirement necessary to ensure protection of his health and safety.
