The book deals with the phenomenon of platform work and contains national reports (Belgium, France, Germany, Italy, the Netherlands, Spain and the United Kingdom), other more transversal reports dealing with the issue of fundamental (collective) workers' rights, as well as the applicable European legal framework. The idea of the book is to underline differences and similarities between the Member States' Systems and the UK System and to understand if there is a common ground of rights and protections for platform workers in the EU. As far as Belgian law is concerned, the classification of the relationship between platforms and app-based workers is not governed by any Belgian-specific regulation. Ordinary law rules are therefore the only ones that qualify this relationship. A specific piece of legislation concerned almost exclusively the taxation of the income made through platforms and the social charges. It did not regulate the relationship between workers and the platform. Th is legislation will be presented in brief. Th is chapter starts by discussing the importance of the phenomenon of platform workers in Belgium (section 1) before turning to the classification of the work relationship by case law (section 2) and by statutory law (section 3) and addressing legislative projects (section 4). Before concluding, a short section presents, in a few words, the organisation of the defence of platform workers’ interests (section 5).
