With ready-mix concrete transport drivers in the capital area halting all deliveries to demand higher transport fees and protection of collective bargaining rights, tension is rising across the construction sector. Builders are responding by adjusting work schedules, but they say prolonged disruption would inevitably lead to construction delays and increased expense.
The National Ready-Mix Concrete Transport Workers' Union stopped deliveries across the capital area starting at 8 a.m. on the 8th. The union said 8,000 members and about 11,000 units of ready-mix concrete transport equipment are taking part in the work stoppage.
The union is demanding a collective wage agreement to raise haulage fees, job security for transport workers, and implementation of collective bargaining. It held a rally in Yeouido, Seoul, on the same day and urged employers to join talks.
The construction industry first moved to respond by adjusting concrete pouring schedules. There have been no confirmed cases yet of a full site shutdown, but if ready-mix supply disruptions drag on, observers say core structural work will inevitably take a hit.
Because ready-mix concrete must be delivered to sites immediately after production, deliveries stopping effectively halts supply itself. If concrete pouring is delayed, subsequent processes will inevitably be affected in sequence.
In particular, large industrial construction sites such as the Samsung Electronics Pyeongtaek Campus and the SK hynix Yongin semiconductor cluster are expected to fall within the impact zone. The industry says it can reshuffle work sequences in the short term, but worries that if the stoppage is prolonged, schedule delays and rising construction costs could materialize.
Ready-mix manufacturers say drivers are independent contractors and therefore not eligible counterparts for collective bargaining. The union, however, is demanding protection of bargaining rights based on court rulings and recognition of the union's establishment by the Ministry of Employment and Labor (MOEL).
Industry officials say a prolonged stoppage could affect not only construction sites but also dwelling supply timelines and move-in plans, and they are closely watching the course of future labor-management talks.
