[Editorial] Concrete Mixer Truckers’ Collective Refusal to Transport Undermines Contract Order and the Rule of Law

The Seoul metropolitan area ready-mixed concrete transport union (Jeonunryeon) began a collective refusal to transport on the 8th, and on the 11th, it even physically blocked the operation of mixer trucks directly run by ready-mixed concrete manufacturers. Concrete pouring has been halted at Samsung Electronics’ Pyeongtaek Campus, and construction on the SK Hynix Yongin semiconductor cluster is also facing disruptions. This situation goes beyond the nature of a wage dispute between labor and management and raises serious concerns about undermining contractual order and the rule of law.

The core of this situation is the breaking of an agreement. Under mediation by the Ministry of Land, Infrastructure and Transport, Jeonunryeon and ready-mixed concrete manufacturers officially reached a provisional agreement on a 4,200 won fare increase (about 5.5%). However, citing its rejection in a union member vote, the union reversed its position and continued the transport refusal. Nullifying an agreement formally reached by the bargaining representatives through a subsequent vote shakes the very foundation of bargaining order. Trust between labor and management and the effectiveness of negotiations can be maintained only when the binding force of agreements is upheld. Furthermore, blocking manufacturers’ legitimate self-operated transport with passenger cars constitutes interference with another party’s lawful business activities, making it difficult to avoid legal responsibility.

The structural background of this situation must also be addressed. In principle, a collective shutdown by independent contractors cannot be regarded in the same way as workers’ constitutionally guaranteed right to collective action. In addition, ready-mixed concrete transport operators, though independent contractors, are demanding integrated bargaining. If integrated bargaining takes place, an upward equalization of transport costs will be unavoidable, and this could further lead to demands for direct bargaining with primary construction contractors. If the system is expanded in a way that collapses the boundary between independent business operators and workers, the resulting cost burden will ultimately be passed on to consumers and industry as a whole. This situation should serve as an opportunity for careful discussion grounded in market realities and contractual order, rather than for hastily broadening the application of status issues for workers in subcontracting and transport sectors.

Ready-mixed concrete has no substitute because it must be poured within 90 minutes of mixing. Process disruptions at construction sites for semiconductor fabs, housing, and infrastructure projects in the Seoul metropolitan area are an issue directly tied not only to construction sites themselves but also to national industrial competitiveness. In the difficult reality of a ready-mixed concrete industry operating at less than 14% capacity utilization, the damage caused by breaking an agreement and blocking worksites will ultimately be borne by consumers, small business owners, and the broader national economy.

The government should actively support the resumption of negotiations while responding firmly, in accordance with law and principle, to illegal acts such as obstructing the operation of company-run trucks. It must recognize clearly that past precedents of overlooking repeated illegal acts have allowed similar situations to worsen. It should be made clear that collective transport refusal and physical obstruction are acts outside the bounds of the law. Amid high inflation and a construction downturn, taking core national industrial sites hostage can never be justified for any reason, and honoring agreed promises is the starting point of contractual order and the rule of law.
