The European Platform to Business (P2B) regulation, adopted on 20 June 2019, was designed to provide a framework for the transparency of algorithms used in online intermediation platforms. Although it was not initially intended to regulate labour platforms, it has proven to be relevant in responding to the challenges raised by this phenomenon. Using a comparatist method of “functional equivalence”, a similarity can be seen between the traditional protections given under European labour law and those that could be provided by the P2B regulation in view of certain issues with labour platforms. Although its individual scope of application, as it currently stands, does not allow for including all labour platforms, its content gives rise to reflection on future European regulations. In future, an equivalent tool would make it possible to consider the labour platform from a global perspective and to find solutions to several process-based issues that are faced by platform workers. Between economic law and labour law, a more comprehensive reflection that includes the protection of workers is being carried out in the legal field.
