The emergence of the platform economy is the most recent model of outsourcing practices and the flexibilization of the organisation of production supported by the development of information and communication technologies. The spread of this business model has led to the expansion of different precarious forms of employment, the most common being the bogus self-employed. The business model based on digital platforms also has the effect of limiting the capacity of trade unions to represent and defend workers, preventing or limiting, for example, resource to collective bargaining. This article compares the trade union revitalisation strategies deployed in Spain and Portugal in the rider sector by traditional trade unions and associations of delivery workers and precarious workers. The article shows how, in both countries, unions have combined organising and mobilisation strategies with actions aimed at influencing political and regulatory expectations. However, there is evidence of a greater experimentation of practices in the Spanish case, as well as a greater impact and influence of their strategies in political terms. The article also reveals important differences between the two countries regarding the relationship between traditional trade unions and delivery workers' associations.
