Three days before a planned large-scale strike by Samsung Electronics workers, the Suwon District Court delivered a ruling that is sending ripples through South Korea’s labor and manufacturing sectors. On May 18, 2026, the court’s Civil Division 31, presided over by Judge Shin Woo-jung, partially accepted Samsung’s injunction request to restrict certain union strike activities, effectively placing significant limits on the unions’ ability to disrupt key operations at the tech giant’s sprawling facilities.
The dispute has been brewing for months, with Samsung Electronics’ two main unions—Samsung Group Super-Enterprise Union Samsung Electronics Branch and the National Samsung Electronics Union—threatening an 18-day total strike starting May 21. Their demands center on abolishing a performance pay cap set at 50% of annual salary and formalizing a policy to allocate 15% of operating profits as performance bonuses. Samsung, for its part, has offered competitive rewards for industry leadership but has balked at institutionalizing the removal of the pay ceiling, according to Yonhap News and JoongAng Ilbo.
As negotiations, mediated by the government, dragged on without resolution, Samsung filed for an injunction on April 16 to prevent what it described as illegal labor actions. The court’s decision, coming after two rounds of hearings on April 29 and May 13, has now set the stage for a tense standoff.
The ruling’s core is clear: even during a strike, certain critical facilities—disaster prevention systems, exhaust and drainage, chemical supply, power supply, and control rooms—must be maintained and operated at normal levels. The court also determined that security operations, such as equipment management, wafer handling, process monitoring, and AI center system management, must continue uninterrupted. This, the court argued, is essential to prevent damage to ultra-precision semiconductor equipment and avoid the risk of product deterioration, a point emphasized in The Hankyoreh and Electronic Times coverage.
Judge Shin’s decision cited the unique nature of semiconductor manufacturing, which is designed for 24-hour continuous operation. "Even a temporary halt can result in wafer loss or equipment damage that requires significant time and cost to repair," the court explained. The risk isn’t just internal: “Production disruptions could affect related industries such as automotive, home appliances, and information communications, causing delays and significant irreparable harm,” the court added, referencing concerns highlighted by JoongAng Ilbo and Kyunghyang Shinmun.
To enforce these obligations, the court imposed hefty daily fines for violations: up to 100 million KRW (about $73,000 USD) per day for each union, and 10 million KRW per day for each union leader. For the Samsung Group Super-Enterprise Union Samsung Electronics Branch, which was specifically cited for suggesting possible facility occupation, the court banned all forms of partial or full occupation of production lines, research facilities, and IT or communications infrastructure. Installing locks or obstructing worker access was also prohibited. According to News1, if all prohibitions are violated, the daily penalty could climb to 300 million KRW for the unions and 30 million KRW for individual leaders.
Not all of Samsung’s requests were granted. The court rejected the company’s plea to ban the National Samsung Electronics Union and its acting chairman from occupying facilities, citing insufficient evidence of imminent occupation. Similarly, Samsung’s bid to prohibit so-called “coercive strike participation encouragement” was denied, with the court noting that such regulations are meant to protect individual workers rather than the employer.
Legal observers say the ruling, while not a total victory for Samsung, strongly favors the company’s position. Attorney Kim Jae-hwa, quoted in JoongAng Ilbo, remarked, “The court’s decision, which recognizes the special nature of semiconductor production and broadly defines security work, places significant constraints on the unions’ ability to conduct disruptive strike actions.” The judgment has been interpreted as a major check on the unions’ strike power, especially given the high stakes for South Korea’s export-driven economy.
Union leaders, however, have sought to downplay the impact. In a statement cited by News1, the union argued, “This injunction only targets dangerous strike activities, not strike action itself. The court’s decision will not affect our planned industrial action.” The union’s legal counsel, Hong Ji-na of Law Firm Majung, added, “There may be some issues with the court’s decision, but we currently have no plans to appeal. We will continue to negotiate in good faith.”
Indeed, negotiations between Samsung and the unions continued on May 18 at the Central Labor Commission in Sejong, with government mediators attempting to broker a last-minute deal. The unions have maintained their threat of a massive walkout, with some 50,000 workers poised to participate if talks collapse. The government, for its part, has reportedly considered invoking emergency powers to prevent a strike that could jeopardize the nation’s semiconductor supply chain, a backbone of South Korea’s industrial might.
The background to this standoff is rooted in the growing assertiveness of Samsung’s unions, which have become increasingly vocal in recent years. Their demands for better compensation and more transparent pay structures reflect broader trends in South Korea’s labor movement, where workers in high-tech industries are pushing back against traditional corporate hierarchies. According to Yonhap News, the unions organized a large rally outside Samsung’s Pyeongtaek campus on April 23, vowing to “change things transparently and achieve the removal of pay caps.”
Samsung, long known for its resistance to unionization, now faces a labor environment that is both more organized and more confrontational. The company’s leadership has expressed a willingness to reward top performance but remains wary of setting precedents that could undermine its management flexibility or global competitiveness.
Industry analysts are watching closely. The court’s insistence on maintaining normal operations for key facilities is seen as a recognition of the sector’s strategic importance—not just to Samsung, but to South Korea’s entire economy. Any prolonged disruption could ripple through supply chains, affecting global electronics, automotive, and consumer goods industries. As the court noted, “Such damage or risk constitutes irreparable harm that cannot be remedied by subsequent monetary compensation.”
With the strike deadline looming and both sides entrenched, the coming days will test the limits of South Korea’s labor laws, the resilience of its manufacturing sector, and the ability of unions and management to find common ground. For now, the court’s ruling has raised the stakes, ensuring that whatever happens next, the eyes of the nation—and the world—will be watching Samsung’s next move.
