Ripple Effects of the Samsung Electronics Union Strike and Institutional Remedies

The labor-management conflict at Samsung Electronics, a symbol of South Korea’s semiconductor industry, has reached the unprecedented critical point of an all-out strike. As of May 2026, the National Samsung Electronics Labor Union, backed by an overwhelming 93.1% approval rate, is continuing last-minute post-mediation proceedings at the National Labor Relations Commission, keeping the industrial sector on edge. This situation goes beyond a dispute at a single company and is intertwined with the immunity framework created by the amendments to Articles 2 and 3 of the Trade Union Act, which took effect last March—the Yellow Envelope Act (Revised Labor Commission Act). It is also showing signs of spreading into a broader spring labor offensive across the entire industrial ecosystem, including demands by an SK hynix subcontractor union for bargaining with the primary contractor, the increasing visibility of strike action within the Kakao community, and solidarity struggles involving Hyundai Mobis affiliates. Accordingly, diagnosing the structural issues and ripple effects of the strike from an economic perspective and seeking an organic solution has become an extremely urgent task for macroeconomic stabilization.

At the heart of the conflict is the permanent institutionalization of the performance compensation system. The union is demanding that 15–20% of annual operating profit be permanently earmarked as the source of performance bonuses and that the cap be abolished, while management is countering with a proposal for a special performance bonus linked to EVA (economic value added) or operating profit, applied on a temporary basis for three years in order to secure investment resources. Applying the Monopoly Union Model at this point suggests that when a union leverages the inelastic labor demand for highly skilled workers to force through an excessive wage premium, the firm, over the long term, reduces its incentive to hire, thereby generating a social deadweight loss. In addition, management’s opaque control over information amplifies information asymmetry. As the Hicks Paradox suggests, the union, by sending the high-cost signal of a strike, enables management’s ability to pay to be revealed through induced learning, thereby extending the duration of the strike in the Ashenfelter-Johnson model. Therefore, as the McDonald-Solow model demonstrates, there is a need to shift toward an Efficient Contract that maximizes total rents on the contract curve by bargaining simultaneously over wages and employment guarantees.

If the strike materializes, its economic shock will be irreversible. Given the nature of semiconductor processes, which require continuous operation, even a one-day stoppage would create immediately visible disruption amounting to KRW 1 trillion per day, and if the utilization rate were to fall by as much as 50%, cumulative losses could swell to as much as KRW 30 trillion. Even more fatal than visible costs such as wafer contamination and inventory disposal is the erosion of long-term trust assets. At the beginning of a supercycle marked by exploding demand for AI infrastructure such as HBM, uncertainty over delivery schedules would encourage major tech customers to defect, handing market leadership to TSMC or SK hynix, while also causing a serious negative externality in the form of cascading job destruction among 1,754 domestic materials, parts, and equipment partner firms. On top of this, the expansion of employer liability under the Yellow Envelope Act (Revised Labor Commission Act) increases firms’ internal governance costs by 15–20%. Restrictions on damage claims for illegal strikes encourage moral hazard on the part of unions, delaying the downward adjustment of the labor resistance curve and thereby accelerating the long-term contraction of R&D spending and the overseas flight of production bases, or capital flight.

In conclusion, in order to eliminate strike risk and establish a win-win equilibrium between labor and management, a comprehensive redesign of the compensation system and dispute-resolution governance is required. Management should build a dashboard that shares ROIC (return on invested capital), TSR (total shareholder return), and a smoothed EVA index in order to break information asymmetry. It should also design a banded performance-sharing system that combines an upper cap, a lower floor, and a clawback mechanism for recovering compensation, so that demands for the unlimited removal of ceilings can be controlled. In addition, a statutory cooling-off system to ease emotional confrontation before a strike and a standing dispute-resolution committee empowered to present mandatory arbitration proposals should be introduced, and essential maintenance work protocols to defend core process utilization rates in advance should be codified. When rule-based predictability is institutionalized to eliminate the national risk premium, the long-term Pareto efficiency of the manufacturing ecosystem will be secured.
