: Hugo Sinzheimer Institute for Labour and Social Security Law
Research in labor and social security law with a focus on the freedom and dignity of working people
About the Institute
The Hugo Sinzheimer Institute for Labour and Social Security Law (HSI) is a research institute of the Hans Böckler Foundation based in Frankfurt am Main (Germany). In the spirit of Sinzheimer, the HSI cultivates an understanding of labour and social security law research that integrates different aspects and includes sociological, legal policy, international and comparative law elements. International law plays a special role, especially the Europeanisation of labour law.
Research Areas and Expertise
The institute's fields of work cover the entire field of labour law, with a focus on collective and international labor law, as well as related social security law. It does not only want to pursue fundamental questions and conduct research, but also to deal with topics of current and practical importance for employees, trade unions and works councils in general. It makes an active contribution to the legal policy debates and aims to make the discussion more objective with scientifically substantiated arguments. To this end, the HSI organises conferences and commissions expert opinions from renowned legal scholars. In addition, it participates in scientific and legal policy discussions by giving lectures, issuing statements, participating in various committees and workshops, and publishing its own papers.

The HSI Report provides conveniently arranged and concise quarterly information on current proceedings before the CJEU and the ECtHR, which are of interest from a labour and social security law perspective. It is an extract from the German-language ‘HSI-Report zum Europäischen Arbeits- und Sozialrecht’, which was recently published in its new format in mid-May 2020 and which also includes political developments in the EU as well as in international labour and social security law. The report is edited by Prof. Dr. Christina Hiessl (KU Leuven), Prof. Dr. Daniel Hlava (Frankfurt University of Applied Sciences) and Dr. Ernesto Klengel (Scientific Director of the HSI).
