Samsung Electronics is facing the prospect of the largest labor strike in its history as more than 45,000 workers threaten an 18-day walkout beginning May 21 over disputes tied to AI-era bonus payouts, Reuters reports.
The labor action centers on disagreements between Samsung management and its union over how profits from the global AI chip boom should be distributed across the company’s semiconductor divisions. The strike could disrupt production of memory chips used in AI data centers, smartphones, and laptops at a time when global demand for advanced semiconductors remains elevated.
According to Reuters, Samsung has proposed significantly larger bonuses for roughly 27,000 employees in its profitable memory chip business, which has benefited from soaring demand and a global memory shortage fueled by AI infrastructure expansion. Workers in Samsung’s foundry and logic chip divisions, however, would receive substantially lower payouts despite contributing to AI-related chip production for customers including Tesla and Nvidia.
Union representatives argue the discrepancy has intensified frustration inside Samsung because employees across divisions often work within the same facilities while facing sharply different compensation outcomes. The foundry division has struggled financially in recent years as Samsung attempted to compete against Taiwan Semiconductor Manufacturing Co., the dominant global contract chipmaker.
Reuters reviewed internal negotiation transcripts and spoke with workers and union officials who described growing internal tensions, employee departures, and concerns about Samsung’s broader semiconductor strategy. The company has pursued an ambitious goal of becoming a fully integrated semiconductor supplier capable of designing, manufacturing, and packaging multiple categories of chips under one organization.
That structure differs from competitors such as Micron, which focuses primarily on memory chips, and TSMC, which specializes in semiconductor manufacturing services. While Samsung’s integrated approach could provide long-term strategic advantages, the current dispute highlights how uneven financial performance across divisions is creating internal pressure.
The Outlook
The potential financial consequences could be substantial. JPMorgan estimates the strike could reduce Samsung’s operating profit by between 21 trillion won and 31 trillion won, or roughly $14 billion to $21 billion. Estimated sales losses could reach 4.5 trillion won.
The labor dispute also comes during a critical period for the semiconductor industry as companies race to secure AI-related supply chains. Samsung remains one of the world’s largest memory chip suppliers and plays a central role in manufacturing components used across cloud infrastructure, AI servers, consumer electronics, and advanced computing systems.
South Korean officials are reportedly monitoring the situation closely because of concerns over broader economic and supply chain effects. Any prolonged disruption at Samsung could affect global technology manufacturers already competing for access to high-performance semiconductors tied to AI workloads.
