Among the most important working life innovations brought about by the technological developments are the new working relations. They differ significantly in their structure, compared to the classical contract types. Crowdwork, a sub-title of platform work, is among them. It is a way of working through the platform where customers and service providers meet over the internet. There is a trilateral relationship in crowdworking: the user (principal), the web-platform and the user (worker). In some crowdwork relationships, the work activity is performed completely on the computer and on the Internet, while in others the work activity is performed in the physical world. Crowdwork raises conflicting issues in terms of private international law. With crowdwork the company or person who is ordering work could be located in one state, the platform itself could be located in another state, and the workers could be located in many other states. In addition, crowdwork companies are often multinational companies. This new business relationship with an international element clearly falls within the scope of private international law. Crowdworking is characterized differently in different jurisdictions. Currently, cases are being heard around the world on the question of whether crowdworkers are “employees” or “independent contractors”. It is mainly the aspects of substantive law that interest legal doctrine. However, questions of private international law are central. My study seeks to answer the question of whether current conflict of laws rules can respond to technological developments. Large multinational companies (e.g. Uber, Deliveroo.) are fighting against a recharacterization of their activities as employment relationships, on the grounds that their business model would not be profitable in this case. “Workers” are bound by standard contracts containing choice of court and choice of law clauses which they can not negotiate and which de facto prevent them from bringing legal proceedings. These issues are worth examining in depth from a comparative law perspective. In addition, other types of “employment relationships” are formed solely on the internet, through internet platforms, which makes it difficult to attach these activities to a particular state. For this type of fundamentally international legal relationship, it is necessary to rethink the criteria of international jurisdiction of the courts and the applicable law regarding crowdworking.
