Korea's National Labor Relations Commission has recognized Hanwha Ocean as the "true employer" of the Welliv branch union, a subcontractor union representing catering workers at the shipbuilder. Hanwha Ocean said it will determine its response after completing a thorough legal review. The ruling is one of the first cases under the revised Trade Union and Labor Relations Adjustment Act — commonly known as the "yellow envelope law" — to broadly recognize a primary contractor's employer status, and is expected to send significant ripples through the shipbuilding industry, where subcontracting is widespread.

The National Labor Relations Commission on Sunday upheld an earlier ruling dismissing Hanwha Ocean's appeal against a decision that required the company to include the Geoje-Tongyeong-Goseong Shipbuilding Subcontractors Branch of the Korean Metal Workers' Union in its bargaining notice. The commission also recognized Hanwha Ocean's employer status with respect to the Welliv branch union — a question left unresolved in the initial ruling.

The commission said that improvements to aging facilities and equipment at workplaces where union members are employed — including kitchens, laundry rooms and commuter buses — "cannot be carried out by Welliv and others alone without Hanwha Ocean's cooperation and approval," adding that Hanwha Ocean qualifies as an employer with the authority to "substantially and specifically control and determine working conditions."

Hanwha Ocean said it received notification of the outcome by text message and plans to finalize its position after a close legal review of the full written decision.

Shortly after the revised labor law took effect in March, Hanwha Ocean published a notice of bargaining demands from subcontractor unions but listed only the Geoje-Tongyeong-Goseong Shipbuilding Subcontractors Branch as a bargaining counterpart. It excluded the Welliv branch union, which has about 450 members and handles catering and facility management. The Welliv branch challenged the exclusion, demanding improvements to working conditions and equal bonus payments. The South Gyeongsang Provincial Labor Relations Commission ruled that the Welliv branch should also be included in the bargaining notice. Hanwha Ocean sought a review of that decision, but the request was rejected — though the question of employer status was left unresolved at that stage.

The ruling has drawn attention because it recognizes a primary contractor's obligation to bargain even over support functions such as catering and commuter transport, not just direct production processes such as shipbuilding. Under the revised labor law's standard of "substantial and specific control over working conditions," the commission found that the workplace safety and working environment improvements sought by the union could not be achieved without the involvement of the primary contractor, which holds authority over the physical facilities.

The decision is expected to have wide implications across the shipbuilding sector and industry more broadly. Other major shipbuilders and large conglomerates could face direct bargaining demands from a range of in-house subcontractor unions — covering not only production workers but also canteen, security and cleaning staff.

The Korea Employers Federation said in a statement Sunday that the commission's decision "does not align with the Ministry of Employment and Labor's interpretive guidelines on the revised labor law," adding that the ministry had cited factory cafeterias as a representative example of arrangements that fall under general supervisory authority in outsourcing contracts and do not constitute structural control by a primary contractor over workers employed by a subcontractor.

The federation also said the commission "created a contradiction by using a primary contractor's legal obligations under the Occupational Safety and Health Act and the Serious Accidents Punishment Act as grounds for recognizing employer status — meaning that faithful compliance with legal duties now leads to bargaining obligations and strike risk with subcontractors." It warned that extending collective bargaining obligations beyond direct production subcontracting relationships to indirect support arrangements "will expand confusion across industry surrounding collective bargaining."

With the commission having recognized Hanwha Ocean as the Welliv branch's true employer, the company may pursue administrative litigation or other legal action. Should the ruling become established precedent, management uncertainty would inevitably grow. Either party may file an administrative lawsuit with a court within 15 days of receiving the written decision if it wishes to contest the ruling.
