TL;DR
Samsung faces an 18-day chip strike from May 21. The PM has warned of $668M daily losses and hinted at emergency powers.
Samsung Electronics and its largest labour union will resume negotiations on Monday in what South Korean Prime Minister Kim Min-Seok has described as “virtually the last chance” to prevent an 18-day strike at the world’s biggest memory chipmaker. If the talks fail, the union’s 41,000 confirmed participants, a number expected to exceed 50,000, will walk out on 21 May.
The prime minister addressed the nation on Sunday, warning that “if the strike becomes a reality, the economic damage that we have to face would be unimaginable.” Kim estimated the cost at up to 1 trillion won ($668 million) for every day Samsung’s chip factories are shut. He signalled for the first time that the government could resort to emergency powers to prevent the strike if it threatened the national economy.
The head of South Korea’s National Labor Relations Commission will participate in Monday’s talks, elevating the negotiations from a corporate dispute to a matter of direct government intervention. Previous government-mediated negotiations broke down on 12 May after 17 hours of marathon talks that union representative Choi Seung-ho described as 16 hours of waiting and one hour of negotiation.

The dispute centres on how Samsung distributes the profits from the AI boom to its workforce. The union wants Samsung to scrap an existing cap on bonuses, allocate 15% of operating profit to worker bonuses, and formalise those terms in employment contracts. Samsung has proposed allocating 10% of operating profit to bonuses, along with a one-time special compensation package that it says exceeds industry standards. Company executives have argued that the union’s demands would be difficult to sustain over the long term.
The financial context makes the union’s position difficult to dismiss. Samsung’s Q1 2026 revenue reached ₩133.9 trillion (approximately $90 billion), with operating profit of ₩57.2 trillion, an eightfold year-on-year increase and the highest quarterly profit in the company’s history. The semiconductor division alone produced ₩53.7 trillion in operating profit, roughly 94% of the total, driven almost entirely by high-bandwidth memory chips used in AI infrastructure. Samsung’s market capitalisation crossed $1 trillion this month, joining TSMC in the semiconductor elite.
While the company’s record profits have doubled the Lee family’s wealth to $45.5 billion in twelve months, workers argue that their compensation has not kept pace. The union’s complaint centres partly on a perceived gap between Samsung’s bonus structure and that of rival chipmaker SK Hynix. The 2025 pay deal satisfied management but left many union members feeling that increases lagged both inflation and the productivity gains Samsung was reporting. The gap between corporate performance and worker compensation is the dynamic driving the current standoff.
Samsung Electronics Chair Jay Y. Lee issued a rare public statement at the weekend, apologising for the company’s “internal issues” causing concern. “Union members, Samsung family members, we are one body, one family,” Lee said at Seoul’s Gimpo International Airport on Saturday. Samsung executives also made an unusual visit to union facilities last week, a gesture that underscored the seriousness with which the company is treating the threat.
The economic stakes extend beyond Samsung. Semiconductors accounted for 37% of South Korea’s total exports in April, up from 20% a year earlier, according to government data. A sustained shutdown of Samsung’s chip fabrication facilities would disrupt the global supply of DRAM and HBM chips at a moment when AI-driven memory shortages are already expected to persist through 2027 and beyond, with hyperscalers booking supply years ahead. Korean media estimate that if the strike proceeds and participation reaches 50,000 workers, total losses could reach 40 trillion won.
The union’s first general strike, in 2024, was relatively short but established that technical and white-collar workers at one of the world’s most important manufacturers were willing to walk out. Each subsequent negotiation cycle has tested how far that leverage extends. The 2026 standoff is the most consequential test yet, because the AI memory supercycle has given Samsung profits that are historically unprecedented, and the workers who run the fabrication lines are asking whether those profits will be shared.
Monday’s talks will determine whether Samsung and the union can close the gap between 10% and 15% of operating profit, a difference that, on Q1 figures alone, represents roughly ₩2.9 trillion ($1.9 billion) annually. The prime minister’s warning about emergency powers adds a dimension that neither side can ignore: the South Korean government has made clear that it views a Samsung chip shutdown as a national economic emergency, not merely a labour dispute. Whether that pressure produces a deal or hardens the positions of both sides is the question that Monday will begin to answer.
