The posting directive was adopted at the end of the nineties. Since then, the nature of subcontracting and employment has changed significantly. Employers using loopholes, taking advantage of the freedom to provide services and freedom of establishment, have developed practices in many sectors that circumvent the interests of workers and circumvent EU and Member State standards. In principle, the Posting Directive fulfils its purpose in the sense of providing minimum working conditions for posted workers, but practice and case studies continue to show, that wage competition, significant differences in labour costs between Member States and social dumping remain a serious problem regardless of the entry into force of the implementing directive. The amendment of the Posting of Workers Directive was clearly aimed at protecting workers, but only after 30 July 2020 does it come to light whether it will achieve its purpose, and what effect it will have on the cross-border employment relationship of workers between Member States.
