With the Samsung Electronics labor union warning of a general strike starting on the 21st, analysts say the actual impact on semiconductor results is likely to be limited. If a strike begins, the company's brand power could take a hit, but contrary to the union's claims, the impact on results would be minimal, according to people on the ground.
According to the industry on the 12th, domestic and foreign investment banks including JPMorgan are estimating damage in the trillion-won range by assuming a "shutdown" of some production lines as a worst-case scenario. However, semiconductor field staff at Samsung Electronics believe that while there could be some impact on production speed, such as the pace of wafer input, the possibility of a shutdown is very low.
Semiconductor processing is not structured like general manufacturing where halting part of an assembly line causes production disruptions. Because hundreds of steps, thousands of tools, automated logistics, and gas, chemical, ultra-pure water, and power systems all operate in tandem, the strike's effect would require precise planning of participation by business sites, shifts, and job categories, according to on-site accounts.
A Samsung Electronics DS division official said, "Memory fabs are highly automated, so only creating bottlenecks in production—rather than the sheer number of absences—can lead to disruptions," adding, "Shift operators, equipment response, AMHS (automated material handling system) and wafer transport, process monitoring, and test and packaging personnel would have to leave simultaneously within specific time windows for production speed to decline in a meaningful way." Analysts say that such structural factors, along with low strike participation, also limited production damage during the 2024 Samsung Electronics semiconductor strike.
Legal constraints also narrow the union's options. Given the characteristics of the semiconductor industry, stringent environmental and safety regulations apply to hazardous gases and other chemicals, meaning the union would have to selectively orchestrate the placement of strike participants to induce production disruptions. Work involving specialty gases, chemicals, exhaust, ultra-pure water, power, and wafer spoilage prevention is legally required to be maintained even during a strike, so to conduct a lawful strike, an organizational structure capable of mapping hundreds of steps and coordinating them is necessary.
Experts broadly agree that even if a Samsung Electronics semiconductor strike drags on and causes disruptions to production lines, the impact on revenue and operating profit would be limited. A representative at a foreign market research firm said, "Even if we assume a maximum 5% slowdown in memory production based on wafer input, the quarterly revenue impact would be estimated at less than 1 trillion won out of total sales of 23 trillion won."
Some argue that if production slows, it could push up the average selling price (ASP) of DRAM and NAND flash, improving revenue and operating profit. As concerns about supply shortages grow and major customers move to secure DRAM and NAND quickly, prices could be driven higher.
If a strike materializes, some observers say government intervention through public authority could become another factor pressuring the union. With the global AI power race intensifying, concerns about production disruptions at the world's No. 1 memory maker are morphing into a "K-semiconductor crisis" narrative, prompting both politicians and the government to raise calls for dialogue. The Ministry of Employment and Labor (MOEL) has already initiated post-mediation procedures to broker talks between labor and management, and management has filed for an injunction to ban industrial action, with the Suwon District Court set to rule before the strike begins.
If even post-mediation collapses, some in labor and business circles suggest the government may invoke the "emergency arbitration" authority vested in the Minister of Employment and Labor. Emergency arbitration is a system that can be activated when industrial action is feared to significantly harm the national economy, and once invoked, industrial action is banned for 30 days. The government is currently maintaining a cautious stance, but if a strike actually begins, expectations are growing that it could play this card.
Still, the more fundamental concern is damage to external credibility rather than financial hits. Samsung Electronics is focused on expanding supply of high value-added products for AI infrastructure such as HBM (high bandwidth memory), high-capacity server DRAM, and enterprise SSDs. Even if production disruptions are not large, if global customers worry about delivery uncertainty, some orders could shift to rivals SK hynix and Micron, creating a windfall for them. Given that process validation and customer qualification take considerable time and expense in the semiconductor industry, there is growing concern that it would be hard to win back customers once they leave.
