Directive (EU) 2019/1937 of the European Parliament and of the Council of 23 October 2019 on the protection of persons who report breaches of Union law, in short, "Whistleblower Protection Directive", is to be transposed into national law by the German legislator by the end of 2021. It is intended to improve the legal protection of whistleblowers and harmonize protection standards. In order to create practical protection, labour law, in particular, is required. For this reason, the IAAEU will examine the need for implementation of the Directive in German law as part of a two-year, externally-funded project of the Fritz Thyssen Stiftung für Wissenschaftsförderung. The focus of the study is on the one hand on how to proceed with the implementation of the Directive in order to anchor whistleblower protection in the regulatory system of German labour law. The second focus in this context is the question of the compatibility of whistleblower protection under labour law with the standards of data and trade secret protection law. The project will run for two years and is funded with a sum of € 40,000.
