Samsung labor dispute threatens to worsen memory chip shortage

On Thursday, more than 35,000 Samsung Electronics workers held a rally at the company’s Pyeongtaek campus in South Korea. The demonstration was organized to signal that the workers are prepared to walk off the job for an 18-day strike next month. The labor dispute is over money, specifically focusing on a performance bonus cap and the redirection of 15% of operating profit.

The dispute highlights a contrast in compensation between Samsung Electronics and its competitors in South Korea:

• Samsung Electronics’ Union Demands: The union wants the company to redirect 15% of its operating profit to workers and eliminate the performance bonus cap.
• SK Hynix Compensation: Rival chipmaker SK Hynix, which has 35,000 employees, is reportedly expected to pay average bonuses of roughly $400,000 per person to its employees, according to local media reports.

The potential strike comes at a critical time for the semiconductor industry, where manufacturers like Samsung Electronics, SK Hynix, and Micron are racing to meet demand. High-bandwidth memory—which refers to specialized memory chips used for AI applications—and DRAM (Dynamic Random Access Memory), which is a type of conventional memory chip, are facing supply constraints. The prices of conventional memory chips, like DRAM, have been increasing since early 2025. This is because AI data centers consume an estimated 70% of high-end memory chips produced worldwide.

If Samsung Electronics’ more than 35,000 workers proceed with the 18-day strike next month, the disruption may compound the ongoing memory chip shortage, with the impacts felt as far away as Silicon Valley. During the Thursday rally, shareholders gathered directly across the street to oppose the union, accusing workers of undermining the company at a crucial juncture.

Why it matters

As AI data centers consume an estimated 70% of high-end memory chips worldwide, any disruption at a supplier like Samsung Electronics risks tightening supply chains for tech firms in Silicon Valley.
