South Korea's memory chip supply chain has been temporarily pulled back from the brink of potential crisis after a series of tense incidents. A South Korean court recently issued a partial injunction against the general strike planned by the Samsung Electronics union, and the government publicly released a strong signal that it would use "emergency arbitration rights", which suddenly cooled down the labor confrontation that might have severely damaged the global memory supply.
Recently, the Samsung Electronics labor union requested that the company pay employees a bonus equivalent to 15% of annual operating profit, approximately US$30 billion, otherwise it will launch an 18-day strike starting from May 21 and lasting until June 7. Market agency KB Securities estimates that if only about 30% to 40% of union members participate in the work stoppage, global DRAM supply may decrease by 3% to 4%, and NAND flash memory supply may decrease by 2% to 3%. The impact will be directly transmitted to global semiconductor and complete machine manufacturers. The salary dispute comes at a time when global DRAM inventories are already at a relatively tight level and can only cover about four to six weeks of demand, making the industry particularly sensitive to the risk of strikes.
As strike expectations rise, downstream prices have already reflected this. The report quoted quotations from the Shenzhen Huaqiangbei market as saying that the price of a typical 8GB DDR4 memory stick has increased by about 20% in the past week. The reasons include panic caused by the breakdown of negotiations between Samsung and the labor union, and echoes the price increase trend previously disclosed by major memory manufacturers in their first-quarter financial reports. Data from market research institutions show that in the first quarter of 2026, both Samsung and SK Hynix confirmed a sharp upward trend in the average selling price of memory products. The former’s average selling price of storage products in the first quarter more than doubled compared with the average price for the whole year of 2025, and the latter’s DRAM quarterly average price increase also reached the mid-double-digit range.
Against this background, the situation in South Korea quickly evolved into a political and economic issue affecting high-level government officials. The Prime Minister of South Korea publicly stated that the current government is considering using the "emergency arbitration power" in the law. Once this rare tool is activated, it can forcibly suspend strike actions for up to 30 days to maintain the normal operation of industries regarded as critical to the country. At the same time, the court issued a partial injunction against the strike plan initiated by the union. If the union fails to comply with the ruling, it will face a daily fine of 100 million won (approximately US$66,500), which objectively increases the cost of the union's continued confrontation.
According to information on South Korean local media and social platforms, some observers bluntly stated that this time the court partially supported the employer’s demands for the so-called "illegal strike", which "actually made it almost impossible to implement the general strike." At the same time, the government's signal that it may "strike all out" is seen as an important bargaining chip in this round of games to force the unions to return to the negotiating table. Under double legal and administrative pressure, this action, which was originally regarded by the outside world as a possible "semiconductor version of a general strike," suddenly lost its initial mobilization momentum.
On the other end of the tough signal, Samsung management has also begun to adjust its negotiation strategies to ease conflicts and buy time. The report pointed out that the company has agreed to replace Vice President Kim Hyung-ho, the chief negotiator who was previously criticized by the union for "lack of understanding of semiconductors", and Yoon Myung-gu from the human resources team of the Equipment Solutions (DS) business group will take over this role. The union had previously made the replacement of negotiators one of the prerequisites for resuming dialogue. Now this condition has been met, clearing an important obstacle for the resumption of negotiations.
The latest progress between the two parties shows that the union and management have restarted negotiations, hoping to find a bonus and treatment package acceptable to both labor and management before a court injunction and the government's possible emergency arbitration intervention, so as to avoid further escalation of the situation. For the global storage supply chain, which is highly dependent on Korean manufacturers such as Samsung and SK Hynix, this means that the probability of the most intense shutdown scenario in the short term has significantly decreased, and market participants can therefore "breathe a temporary sigh of relief." However, there are still considerable differences between the two parties on core issues such as bonus amounts, distribution mechanisms and future labor relations framework. The final direction of this storm remains to be verified by the results of subsequent negotiations.
From a more macro perspective, this round of conflict exposes the contradiction between workers' expectations for sharing corporate profits and narrowing the salary gap during a high-business cycle, and large technology companies' long-term strategies such as capital expenditure and global expansion. In a context where storage prices have risen sharply and industry profits have significantly recovered, Samsung’s labor union’s demand for “15% of operating profits as a bonus” and the social discussions it triggered may have a demonstration effect on the future salary and labor negotiation models of the Korean and even global semiconductor industries. For the global market, although the strike has temporarily eased, it has once again highlighted the high concentration of key components in a few suppliers and the huge impact of production capacity in a single region on terminal prices and supply chain security.
