Private international law: an appropriate means to regulate transnational employment in the European Union?

The regulation of transnational employment in the European Union operates at the crossroads between private international law and internal market rules. The private international law rules are currently laid down in the Rome I regulation. This regulation is complemented by the Posted Workers Directive, a directive based on the competences of the EU in the field of free movement of services. The current contribution first describes the rules which determine the law applicable to the employment contract under Article 8 Rome I Regulation and the way these rules are interpreted by the CJEU before critically analysing these rules and the reasoning that seems to lie behind the court’s interpretation (section 2). The law applying to the contract is, however, only of limited relevance for the protection of posted workers. This is due inter alia to the mandatory application of certain rules of the country to which the workers are posted, even if a different law governs their contract. This
application of host state law is based on Article 9 Rome I Regulation in conjunction with the Posted
Workers Directive. Section 3 describes the content of these rules and the - to some extent still undecided - interaction between the Rome I Regulation and the PWD. The conclusion will be that there is an uneasy match between the interests informing private international law and the interests of the internal market, which is not likely to be resolved in the near future.
