At a critical juncture when global demand for AI chips is booming and memory production capacity is tight, Samsung, the world's largest DRAM manufacturer, is facing the largest crisis in semiconductor history.Labor-Management ShowdownAfter negotiations with management regarding "bonus system reform" completely broke down, Samsung's largest union confirmed that more than 48,000 employees (approximately 38% of South Korea's total workforce) will launch a protest starting May 21.18-day strike.
Since most of the striking employees belong to the core memory division, this labor conflict could not only paralyze Samsung's cash cow production lines, but also affect the lifeline of the global AI industry's memory supply chain.
The core issue that led to the breakdown in negotiations was not a pay raise, but rather "unlimited profit sharing."
The trigger for this conflict was not simply a basic salary adjustment, but rather a huge difference in the structural understanding of the "performance bonus system" between the two sides.
The union put forward three core demands:
• Remove bonus cap:The current limit on bonus payments of 50% of annual salary will be abolished.
• Fixed profit sharing:The requirement is to allocate 15% of the company's annual operating profit directly to the employee performance bonus pool.
• Basic salary increased by 7%.
Union spokesperson Choi Seung-ho stated that the union had accepted the final settlement proposal put forward by the South Korean National Labor Relations Committee (NLRC), but it was rejected by the management. Although Samsung management had offered a one-time bonus of approximately $34, claiming it was among the industry's leading amounts, the management firmly opposed the "permanent removal of bonus caps" and the practice of "linking bonuses to operating profits at a fixed percentage," arguing that this would undermine the company's fundamental management principles.
The reason the union is taking such a tough stance is due to the precedent set by its rival, SK Hynix.
In September of last year, SK Hynix reached an agreement with the union, promising to allocate 10% of its annual operating profits as bonuses for the next ten years and removing the cap on bonuses. This has created a strong sense of relative deprivation among Samsung employees, especially given that Samsung's chip division did not pay any performance bonuses in 2024 due to losses, further exacerbating the labor-management conflict.
Bans and government pressure: Will production lines really come to a standstill?
Facing the impending strike, Samsung did not sit idly by. On May 18, the Suwon District Court partially approved Samsung's application for preliminary injunction, mandating that the union maintain the normal attendance of 7087 key personnel during the strike to ensure the normal operation of security facilities and wafer loss prevention operations. Violators will face a hefty fine of up to 100 million won (approximately US$72,000) per day.
Although the court ruling temporarily stabilized Samsung's stock price, the two sides still disagree on the definition of "maintaining normal manpower" (weekday standard and holiday standard).
Furthermore, the South Korean government is facing immense pressure. Prime Minister Kim Min-seok has stated that if the situation spirals out of control, the government may invoke its "emergency adjustment" authority to forcibly suspend the strike for 30 days. Samsung has also issued a statement emphasizing, "We will not give up on dialogue until the very last moment, and a strike should not occur under any circumstances."
Global supply chain turmoil: HBM's high-bandwidth memory capacity is running low, creating an opportunity for Taiwanese manufacturers to shift orders.
Samsung currently holds approximately 36% of the global DRAM market share and is a key supplier of HBM high-bandwidth memory required for AI chips such as those from NVIDIA.
• HBM4 mass production is hampered:Samsung only started mass production of HBM4 in February this year, and its total production capacity for 2026 has already been sold out. May and June are the critical period for stabilizing yield and rushing to deliver. If the production line is disrupted, it will directly threaten the delivery schedule of next-generation AI chip platforms such as NVIDIA Vera Rubin, and may even cause Samsung to hand over the HBM high-bandwidth memory market share that it has worked so hard to catch up with to SK Hynix.
• The global memory market is undergoing a reshuffle:Market research firm TrendForce estimates that if the Samsung union strike is fully implemented, it could impact global DRAM supply by approximately 3% to 4%, while NAND supply is estimated to decrease by 2% to 3%. JPMorgan Chase is even more pessimistic, predicting that Samsung's operating profit loss could reach as high as $208 billion.
• Market chain reaction:The news of the Samsung union strike has already triggered volatility in global memory stocks, with companies such as Micron and WD experiencing consecutive days of declines in their share prices. In contrast, Taiwan's memory supply chain (including companies like Nanya Technology, Phison, Winbond, and ADATA) has shown strength due to market expectations of a potential "order transfer effect" and rising spot prices.
Analysis: The Growing Pains of "Profit Redistribution" in the AI Era
Samsung's strike involving more than 40,000 people may appear to be a labor dispute within a single company, but in essence, it represents the structural growing pains that the semiconductor industry must face as it enters the "era of AI exorbitant profits."
When the chip division's quarterly operating profit margin soared past 60%, approaching the levels of TSMC and NVIDIA, engineers on the front lines of production naturally demanded to break through past salary ceilings and fight for more direct profit sharing. This competition is not only about whether Samsung can keep up with SK Hynix in the HBM high-bandwidth memory race, but it will also set a new benchmark for the salary structure of the global semiconductor industry.
Before the strike deadline on May 21, there is still a tiny chance for a final negotiation in this multi-billion dollar tug-of-war.
