Summer labor struggles are failing to reach a resolution, and strikes are occurring consecutively at Hyundai Motor and POSCO, spreading the threat of strikes throughout the entire industrial sector. Hyundai Motor has entered a full-scale strike for the first time in 10 years, and POSCO has secured its first right to collective bargaining since its establishment. This situation is attributed to the increasing demand for negotiations between head offices and subcontractors following the implementation of the Yellow Envelope Act. As head offices often refrain from participating in negotiations, there are growing concerns about the prolonged labor-management conflicts. The labor community plans to escalate its struggle ahead of the September regular National Assembly session and state audit, and is scheduled to hold a resolution meeting urging head office-subcontractor negotiations.
