The rise of the sharing or gig economy has enabled a host of new opportunities for private individuals to sell their labor in a flexible way via online platforms. Initially, these platforms were meant to offer individuals the possibility to earn a little extra money on the weekends and spare time, e.g. by driving others in one’s car. As these platforms have matured, and a growing share of the service providers (“gig workers”) depend on them for their main income, calls have been made for improving their working condition. As each individual gig worker has very little bargaining power vis-à-vis a platform, one way to secure this would be for them to engage in collective bargaining. However, this might conflict with EU competition law. The paper explore this conflict and indicate some possibilities to remedies this. Further, parallels are made to US where identical issues have emerged.
