Samsung Averts Strike With 10.5% Profit Bonuses for Union

South Korean authorities and Samsung Electronics reached a tentative agreement with the company's largest union late Wednesday, heading off a strike that could have disrupted memory chip supplies worldwide. Nearly 48,000 workers had planned an 18-day action starting May 21, targeting the firm's dominant memory division that accounts for a large share of its profits and global market position.

The union had demanded removal of the existing cap on performance bonuses, which stood at half of annual base pay, and sought a larger slice of operating profits for the overall bonus pool. Rival SK Hynix had already lifted similar restrictions for its employees, giving the Samsung workers leverage in negotiations that dragged on for months. Union leader Choi Seung-ho said members will vote on the deal between May 22 and 27, with any final pact dependent on the outcome.

Samsung described the breakthrough in measured terms, pledging a more constructive relationship with labor going forward. The company avoided what could have been significant production shortfalls at a time when demand for advanced chips remains tied to artificial intelligence expansion and data center growth. Markets reacted quickly to the news, with South Korea's benchmark KOSPI index climbing more than 8 percent on Thursday to close at 7,815.59. Samsung shares gained over 7.5 percent while SK Hynix rose more than 11 percent.

Broader trading reflected optimism beyond the labor resolution. U.S. chipmaker Nvidia reported record quarterly profits of $58.3 billion, and its leadership pointed to robotics and physical AI as future drivers. That outlook lifted related South Korean stocks, including automotive names Hyundai and Kia that each advanced around 13 percent. Trading volume surged past 616 million shares, with advancing issues outnumbering decliners by a wide margin.

The episode underscores how concentrated power in a handful of semiconductor producers leaves national economies exposed to labor disputes and supply interruptions. Samsung commands more than one-third of the global DRAM market and over a quarter of NAND flash output, according to industry data. Any extended stoppage would have rippled through electronics manufacturing and cloud computing providers far beyond South Korea's borders.

Workers framed their push as a matter of fairness after years of restrained compensation relative to company performance. The tentative terms suggest management recognized the risks of prolonged confrontation amid strong industry tailwinds. South Korea's currency also strengthened against the dollar as investor sentiment improved.

Further details on the bonus structure remain subject to the membership vote, but the agreement has already eased immediate pressure on production schedules. Global chip buyers and investors will watch closely for signs that similar tensions could surface at other major manufacturers.
