On the 10th, the Yellow Envelope Act, which amends labor union and labor relations coordination laws, will come into effect in South Korea. In response, the subcontractor unions under the Korean Confederation of Trade Unions (KCTU) are mobilizing approximately 130,000 members to demand collective bargaining with primary employers. Anticipating the new legal obligations imposed on primary employers regarding negotiations with subcontractor unions, the KCTU announced its campaign plans in a press conference held on the 5th in Seoul. The movement includes a rally urging primary employers to engage in negotiations alongside the formal requests, as they prepare for potential strikes scheduled for mid-July.

In coordination with various industry unions, the nationwide metalworkers' union indicates that 26 subcontractor and non-regular branches will submit negotiations requests to primary employers once again on the 10th. Additionally, workers from public institutions, universities, and different construction job sectors will also join in demanding negotiations, pointing to an expansive mobilization across many sectors including public transport authorities and major construction firms. The varied nature of unions involved demonstrates the broad impact of the Yellow Envelope Act, reinforcing the call for improved labor conditions across the board.

Despite this collective action, the negotiation process may not proceed smoothly. There are indications that primary employers might resist formal negotiations, citing various reasons or refusing to acknowledge their responsibilities. If primary employers do not officially announce the bargaining requests, the involvement of labor committees may be needed to enforce compliance. This complex dynamic highlights the potential obstacles subcontractor unions may face as they seek to secure their bargaining rights in the new legal landscape, putting significant pressures on labor relations in the country.
