Key Points
- Foundry chip production decreased 58% while memory chip output declined 18% during overnight shift walkout
- Workers seek performance bonuses equivalent to 15% of operating profit plus elimination of bonus caps
- Extended strike planned for May 21 through June 7 pending negotiation outcomes
- Prolonged work stoppage could reduce global DRAM availability by 3-4% and NAND supply by 2-3%
- Share price dropped 2.23% to close at 219,500 won while KOSPI remained relatively stable
Samsung Electronics faces mounting pressure from its labor union, creating ripples across semiconductor markets worldwide.
Approximately 40,000 union members gathered at Samsung’s Pyeongtaek facility on April 23, choosing to skip their overnight shift scheduled from 10 p.m. Thursday through 6 a.m. Friday. The immediate impact resulted in foundry chip manufacturing declining by 58%, while memory chip production fell 18% during that single shift.
Samsung offered no statement regarding the situation.
The union — having recently achieved majority representation status for the first time in company history — seeks compensation changes including performance bonuses calculated at 15% of operating profit. Workers additionally demand complete removal of the current bonus ceiling structure.
Management faces an ultimatum: reach an agreement or confront a comprehensive general strike scheduled from May 21 through June 7.
Potential Supply Chain Consequences
Market analysts are monitoring developments carefully. KB Investment & Securities research head Kim Dong-won noted in his report that the labor action “will serve as a key variable that deepens supply shortages” considering current memory market constraints.
Samsung commands a 36% share of the global DRAM market alongside a 32% position in NAND flash. Extended work stoppages at Pyeongtaek and Hwaseong production sites could diminish worldwide DRAM availability by 3-4% and reduce NAND supply by 2-3%, Kim’s analysis indicates.
Following any work stoppage conclusion, Kim projects an additional two to three weeks would be required to restart and stabilize automated manufacturing systems.
Participation rates represent a critical factor. The July 2024 strike drew approximately 15% of union membership, which contained market disruption. Current analyst projections suggest 30,000 to 40,000 members — representing roughly 30-40% of total union membership — could participate should the strike proceed.
Investor Opposition
The union’s demands face resistance from multiple quarters. Fulfilling the wage proposals would necessitate approximately 45 trillion won ($32 billion) in bonus distributions, sparking worries about reduced capital available for facility expansion and research initiatives.
Representatives from the Korea Shareholders’ Movement Headquarters organized a counter-demonstration near the union gathering location, contending the compensation demands could directly harm shareholder interests during a semiconductor industry upswing.
The prevailing analyst perspective suggests earnings projections will likely remain unchanged even with strike action. One unnamed analyst from a leading securities firm identified the primary concerns as investor sentiment and immediate supply-demand dynamics rather than sustained profitability.
“Unless the strike is prolonged or involves radical actions such as damage to production facilities, it has not had a fatal impact,” the analyst said.
Samsung shares concluded trading at 219,500 won on April 24, representing a 2.23% decline for the session. The KOSPI index finished at 6,475.63, down a modest 0.18 points.
