Samsung Electronics is confronting an intensifying labor dispute. While the artificial intelligence boom has driven the company's profits to record highs, the labor union is leveraging this success to pressure management for a larger share of AI-related gains, using the threat of a large-scale strike as a bargaining chip. This has already caused tangible disruptions to core chip production lines.
The union reported that during the night shift on April 23rd, worker attendance at a rally led to a sharp decline in output. Production at the company's wafer foundry lines dropped by approximately 58%, while memory chip output also fell by about 18%. Samsung declined to comment on the reported production losses. The union has further warned that if negotiations fail, it will initiate a large-scale strike lasting 18 days, starting on May 21st.
Approximately 30,000 to 40,000 people reportedly gathered outside Samsung's Pyeongtaek semiconductor complex for the rally. The union is demanding that 15% of the company's annual operating profit be allocated as bonuses for employees in the chip division, a total exceeding 40 trillion won (approximately $27 billion), which would average over $400,000 per worker. A Samsung spokesperson stated that the company remains committed to reaching an agreement in wage negotiations as soon as possible.
The underlying context of this shutdown risk is Samsung's explosive earnings expansion. The company forecasts its operating profit for the first quarter of 2026 to surge by approximately 700% year-on-year. Analysts further predict that Samsung could potentially surpass NVIDIA by 2027 to become the world's most profitable company. The disparity between soaring profits and employee compensation is the central tension fueling this labor standoff.
The demands from Samsung's largest union include allocating 15% of annual operating profit to a bonus pool for chip division staff. This percentage reportedly corresponds to an amount over 40 trillion won (around $27 billion), averaging more than $40,000 per worker. The union is also demanding a 7% pay increase.
Management's current proposal offers a different structure: allocating 10% of operating profit to bonuses, coupled with a 6.2% salary increase and a package of additional benefits, including favorable mortgage loan support. This proposal has been rejected by the union.
Choi Seung-ho, the head of Samsung's largest union, stated at the rally, "The company talks about crisis every year, but during those crises, it wasn't management that supported Samsung Electronics—it was the workers. It is the union members who manufacture the products, improve processes, work through the night, and enhance yields, making the company a global leader in semiconductors."
The union is using the compensation structure at rival SK Hynix as a benchmark. SK Hynix reportedly agreed last year to allocate 10% of its annual operating profit to a performance bonus pool.
The production impact from the single rally clearly signals the potential scale of disruption a full strike could cause. The fact that one event led to a 58% drop in a single shift's wafer foundry output and an 18% decline in memory chip production—with the more labor-intensive foundry lines being hit particularly hard—highlights the vulnerability.
In contrast, the last work stoppage initiated by the Samsung union in 2025 lasted only three days, with a relatively contained impact on production. The threatened 18-day strike, running from May 21st to June 7th, would be far more extensive in both scale and duration than any previous action, potentially causing incalculable disruptions to Samsung's supply chain.
Samsung's massive profit surge is providing the union with significant leverage in negotiations. The company, along with SK Hynix and Micron, has been rapidly transitioning production to high-bandwidth memory (HBM) for use in NVIDIA's AI accelerators. Samsung also recently commenced commercial shipments of the next-generation HBM4 to customers. The company expects total sales for Q1 2026 to reach 133 trillion won (approximately $88.2 billion), significantly exceeding market consensus estimates of 116.81 trillion won. Operating profit is forecast to be about 57.2 trillion won (around $37.8 billion), representing a roughly 700% year-on-year increase and a 184% quarter-on-quarter jump from the 20.1 trillion won recorded in Q4 2025.
Analysts at KB Securities project that Samsung's full-year operating profit for 2026 will reach 327 trillion won, climbing further to 488 trillion won in 2027. At that level, it could potentially edge out NVIDIA to become the world's most profitable publicly listed company.
This conflict reflects a deeper evolution in Samsung's internal power structure. For decades, Samsung successfully maintained distance from unions. However, in recent years, organized labor has gained a firmer foothold within the company, emboldening employees to publicly voice their demands more assertively.
The next critical juncture for negotiations is May 21st. If management and the union fail to reach an agreement by that date, Samsung's pivotal role in the global AI supply chain will face a direct and severe test.
