Samsung Electronics suffered one of its sharpest market-value declines in recent years on Wednesday after failing to secure a wage agreement with its labor union.
South Korea’s largest company lost as much as 99.07 trillion won, or about $66.18 billion, in market capitalization during intraday trading after its shares fell as much as 6.09% from Tuesday’s close of 279,000 won.
The selloff followed growing fears that a planned 18-day strike by tens of thousands of workers could severely disrupt chip production at a critical moment for the company’s AI ambitions.

More than 41,000 workers are expected to participate in the walkout beginning May 21 if negotiations fail, according to the union. The threatened strike would mark a major escalation in labor tensions at a company long viewed as one of South Korea’s most powerful and historically anti-union conglomerates.
The confrontation is seen as a part of a broader transformation underway inside the global semiconductor industry, where competition for engineering talent is becoming almost as important as access to manufacturing capacity and advanced chip technology.
“I would like to express some regret that none of the agenda items requested by the union have been addressed,” union representative Choi Seung-ho told reporters Wednesday, according to Reuters.
The Demand Fueling the Chaos
At the center of the dispute is Samsung’s performance-based bonus structure, which workers argue no longer adequately reflects the company’s soaring profits from the AI-driven semiconductor boom. The union is demanding that Samsung allocate 15% of annual operating profit to employee performance bonuses, remove payout caps, and institutionalize the compensation framework.
Samsung management reportedly countered with an offer to allocate 10% of operating profit to bonuses while also providing a one-time special compensation package, according to South Korea’s Yonhap News Agency.
The gap between those positions underscores how dramatically expectations have shifted inside the semiconductor industry since artificial intelligence transformed demand for advanced memory chips and computing infrastructure. Samsung’s rival SK Hynix has emerged as one of the biggest beneficiaries of the AI spending boom because of its dominance in high-bandwidth memory chips used in AI servers and accelerators. The company has also offered richer long-term compensation packages, increasing pressure on Samsung to retain top engineering and manufacturing talent.
The stakes for Samsung are unusually high because the company is attempting to recover lost ground in the AI semiconductor race after falling behind rivals in some critical areas of advanced memory production.
Analysts say compensation has become a strategic issue rather than merely a labor matter. If Samsung accepted the union’s proposal to allocate 15% of operating profit to bonuses, the company could face average annual incentive payouts of roughly $46 billion over the next five years, based on analyst forecasts compiled by Visible Alpha.
That would represent one of the most aggressive worker-compensation frameworks in the global technology sector and could materially affect profitability, capital expenditure planning, and shareholder returns.
The union has attempted to demonstrate its leverage ahead of the proposed strike. Labor representatives said a rally involving roughly 40,000 workers on April 23 resulted in a 58% drop in foundry production and an 18% decline in memory-chip production for that day alone. The union further warned that an 18-day strike could inflict losses of as much as 30 trillion won, or approximately $20 billion.
Such disruption would come at an especially delicate time for Samsung. The company reported first-quarter operating profit of 57.2 trillion won in April, representing a staggering 750% increase from the same period a year earlier, driven primarily by surging semiconductor demand linked to artificial intelligence infrastructure.
The rebound marked a dramatic recovery after the memory-chip downturn that battered the semiconductor industry in recent years. Yet Samsung’s strong earnings have also intensified pressure from workers demanding a larger share of the gains.
Samsung experienced its first major modern labor revolt in 2024 when a union representing about 28,000 workers staged a strike lasting nearly a month. At the time, the operational and financial impact appeared manageable, and the company largely avoided major concessions on wages.
This time, however, the balance of power looks different. Union membership has reportedly grown to more than 90,000 workers, representing roughly 70% of Samsung’s workforce, dramatically increasing labor’s influence inside the conglomerate.
Government Intervention Helped But Not Absolutely
The dispute has become so serious that South Korea’s government publicly intervened in an attempt to prevent a strike. Finance Minister Koo Yun Cheol said the government “deeply regrets” the failure to reach an agreement and warned that “strikes must never happen under any circumstances.”
“Samsung Electronics is an important company that the world is watching,” Koo wrote in a post on X. “Considering the current management situation and its impact on the national economy, both labor and management sides must continue to strive to achieve principled negotiations.”
The government’s response underpins Samsung’s enormous importance to South Korea’s economy. The company is not merely the country’s largest corporation. It is one of the central pillars of South Korea’s export-driven economic model, with influence spanning semiconductors, smartphones, consumer electronics, and industrial supply chains.
Any prolonged disruption to Samsung’s chip production could ripple through global technology markets already strained by AI-related supply shortages and geopolitical tensions surrounding semiconductor manufacturing.
Investor sentiment improved later in the trading session after remarks from Prime Minister Kim Min Seok, who instructed officials to “manage the situation closely” and provide “active assistance” to prevent a strike.
Samsung’s shares later reversed earlier losses and turned positive, suggesting investors interpreted the government’s intervention as a sign authorities would seek to avoid severe industrial disruption.
