Samsung reaches tentative deal with workers to avert memory chip strike
Samsung Electronics has reached a tentative agreement with its workers' union just hours before more than 47,000 employees were due to begin an 18-day strike. The deal averts a crisis at a central node of the global memory chip supply chain.
The Samsung Electronics workers' union had announced that more than 47,000 of its members would begin an 18-day strike from Thursday. The strike had been put on the agenda after bonus payment negotiations broke down in early May. Stoppages were expected at Pyeongtaek, Hwaseong and other domestic manufacturing centres.
On Wednesday afternoon, both the workers' union and the company management announced that a deal had been reached after the discussion. The union's website confirmed strike plans had been suspended pending a ratification vote. The vote will take place next Monday; members are widely expected to accept the offer.
The details of the agreement have not yet been fully disclosed, but internal sources reached by Reuters said the package includes an annual pay rise (4.5 percent), a performance-related additional bonus (4 million Korean won per year, approximately $3,000) and improved health-insurance benefits for night-shift staff.
The strike threat had alarmed the global tech sector. Samsung Electronics controls roughly 40 percent of the world market for DRAM and NAND flash memory chips. An 18-day shutdown at Pyeongtaek would have created a significant bottleneck in the global memory chip supply chain — particularly affecting production of HBM3E and similar high-bandwidth memory for AI data centres.
Markets reacted positively to news of the deal. Samsung Electronics shares in Seoul closed 3.8 percent higher on Wednesday. SK Hynix and other rival memory makers fell 2 to 4 percent on the loss of an expected competitive advantage. Buyer companies such as Apple, Microsoft and Nvidia reacted mildly positively.
The relationship between Samsung and its union has been tense in recent years. In 2024, Samsung experienced the first major strike to break with its 80-year-old traditional 'good-company-good-worker' model (three days). In early 2025, a new union leader was elected; that leader has adopted a more aggressive negotiation stance. Wednesday's deal is seen as a win for the preservation of union strength.
The global memory chip market is currently in shortage. Explosive growth in AI data centres has driven extraordinary demand for HBM (high-bandwidth memory). Samsung is one of the two main companies supplying HBM3E for Nvidia's H200 and B100 GPUs (the other is SK Hynix). An 18-day strike could have deepened the bottleneck in this market further.
The Korean government played a quiet role in the negotiations. The Ministry of Labor and Employment provided mediation services to the two sides. For the government, Samsung Electronics is a strategic asset for the national economy — it contributes around 14 percent of Korean GDP and provides 18 percent of foreign exchange earnings.
Looking ahead, the rebuilding of balance in Samsung Electronics' industrial relations is expected to be a long process. If the deal is ratified at Monday's vote, the contract will run until May 2027. However, if AI chip demand continues, the union may reach a stronger bargaining position in the 2027 negotiations. For investors, Wednesday's deal provides short-term relief, but Samsung's labour relations remain a longer-term strategic risk.
