The International Labour Law demands against the background of increasing numbers of cases with international regard higher standards for legal advice: Which law is applicable, what is laid down by law, what is standardised in Europe? The handbook „International Labour Law under the Rome Conventions“ offers a full academic examination of the conflict-of-laws questions in Labour Law, as far as they are standardised in Europe (Rome I and for industrial action Rome II). It also deals with the unregulated or only partial regulated field of the law referring to the applicable employment law and answers detailed conflict-of-laws questions of the international Labour Law, especially: classification law governing formal validity connection factors for capacity and contractual capability connection factors for the employment contract special connecting rule for overriding mandatory provisions creation of the contract subject matter of the contract termination of the contract Post-termination effects of the employment contract industrial action Especially practically oriented are the numerous legal comparative advices, which make a conflict-of-laws classification of the various institutes of the different legal systems possible. Advice in cases with international reference is often given in English and therefore the English version helps to acquire the presumed professional vocabulary. Professor Dr. Olaf Deinert is director of the Institute of Labour Law at the University of Göttingen and one of the most prominent jurists in the field of European and International Labour Law.
