On July 15, 2019, scientists from Trier and several Austrian universities met at the University of Salzburg for an informal exchange on legal issues of platform-based work. Prof. Dr. Dr. h.c. Monika Schlachter, Dr. Thomas Klein, Katrin Treppschuh und Dominik Leist represented the IAAEU. At the event, short keynote speeches on various aspects of the main topic were presented from both a German and an Austrian perspective, followed by a cross-national discussion. Dr. Thomas Klein gave a lecture on civil law issues of platform-based work. A German perspective on the labour law aspects was provided by Katrin Treppschuh with a contribution on individual law and by Dominik Leist with a presentation on collective labour law issues in platform-based work. Dr. Thomas Spitzlei (University of Trier) examined the social law aspects from a German perspective. The discussion revealed similar problems in German and Austrian law, especially with regard to civil law and individual labour law issues. Collective labour law raises different questions, given the different systems at the national level. At the European level, however, these are overlaid by competition law aspects, so that there are also common points of contact in this respect.
