Thousands of workers [1] marched through central Seoul near Gwanghwamun Square on May 1, 2026 [2], to demand stronger labor protections.

The demonstration highlights the growing tension between South Korea's temporary workforce and primary contractors. As living costs rise, non-regular workers seek legal frameworks that allow them to negotiate wages and conditions directly with the companies that control their employment.

The rally was organized by the Korean Confederation of Trade Unions (KCTU). Participants focused their demands on the right to collective bargaining with primary contractors, arguing that current structures leave temporary employees without sufficient leverage. The KCTU said the event was timed to coincide with International Workers’ Day to amplify their message on a global stage.

Protesters called for a shift in how the law treats non-regular employees. These workers often face precarious contracts and lower pay than their permanent counterparts, a disparity that has fueled recent labor unrest in the capital. The KCTU said that stronger legal protections are necessary to prevent the exploitation of the temporary workforce.

While the rally remained focused on policy changes, the scale of the turnout reflects a broader systemic struggle within the Korean economy. The demand for collective bargaining is central to the movement, as it would allow workers to negotiate not just with staffing agencies, but with the primary firms where they actually perform their labor [1].

This mobilization signals an intensifying push to dismantle the 'two-tier' employment system in South Korea. By demanding bargaining rights with primary contractors rather than secondary agencies, the KCTU is challenging the legal shield that allows large corporations to avoid direct responsibility for the welfare of a significant portion of their operational workforce.
