Abstract:The platform economy poses a challenge to the exercise of collective labor rights for online workers. The mechanism for the exercise of collective labor rights was set up in the era of large-scale industry, in which union membership was closely integrated with labor relations. The platform economy has overturned the traditional employment methods of enterprises. However, online workers are facing the dilemma of identifi cation of laborers. It is diffi cult for them to join enterprise trade unions and to negotiate collectively with platform enterprises operating across regions through the grassroots trade unions. The study insists that, in the face of the challenges posed by the platform economy, it is necessary to break the myth of labor relations by including online workers in the category of employees, establishing or approving cross-regional high-level industries trade unions for them, exploring ways to conduct collective consultations with platform companies, and responding to the demands of online workers for collective labor rights protection with the modernization of union governance.
