90,000 Samsung workers at risk of strike signals a shift in Korea's labor market

South Korea’s potential 90,000-strong Samsung workforce strike highlights how a highly protective labor regime can reshape hiring behavior, fragment the labor market, and increase the likelihood of labor unrest. A broad-based stoppage planned for May 2026 is being viewed as a sign of market disequilibrium.

In March 2026, more than 93% of roughly 66,000 Samsung employees who voted supported the strike plan, setting up a stoppage expected to run from May 21 to early June. Samsung’s unionized workforce is now around 90,000, representing more than 70% of the group’s total employees in Korea.

If the strike proceeds as planned, about half of the chip output at the Pyeongtaek complex could be affected. Samsung produces all of its DRAM and two-thirds of its NAND in Korea, at a time when demand for AI-related chips is rising. Even a short supply disruption could ripple across sectors including autos, consumer electronics, and data centers.

Union demands and the wage-bonus dispute

The union’s demands include a 7% base wage increase, greater transparency in bonus schemes, and the removal of caps on performance bonuses. Samsung management has proposed a 6.2% increase plus additional benefits, but has refused to remove the bonus cap, citing concerns about long-run financial balance.

The gap reflects a broader tension in periods when corporate profits rise: how value is shared can become more contentious, particularly when firms have limited flexibility to adjust costs and compensation structures.

Labor policy shift in Korea

Korea’s current labor issues trace back decades. During the industrialization era of the 1960s to the 1980s, growth relied on cheap labor and strict discipline, while unions were limited. Workers faced long hours, poor conditions, and minimal protections.

A major turning point came in 1987, when the worker movement surged and pushed the government toward reforms. The right to organize unions expanded and labor laws were tightened to protect workers.

In more recent years, the system has continued to be strengthened, including reforms such as the Yellow Envelope Act in 2025. The reform broadened union bargaining power and limited firms’ ability to sue for damages in the event of a strike.

Under the regime described, dismissals require “just cause” in management terms, a standard that is not clearly defined and is difficult to meet in practice. Generally, firms can fire only for clear illegal acts such as theft or embezzlement, while poor performance, low sales, or not meeting KPIs are usually not treated as just cause.

If a dismissal is ruled unlawful, the firm must rehire the employee and pay compensation. Disputes often resolve in workers’ favor, and lengthy legal processes increase costs and risk for employers. OECD assessments place Korea among the more highly protected labor markets among advanced economies.

Two-tier labor-market dynamics and corporate responses

Given the adverse legal environment, firms adjust behavior to minimize risk. When firing is difficult and costly, hiring decisions become more cautious. Instead of expanding the official workforce, many firms shift toward contract, temporary, or outsourced workers.

As a result, informal employment is high. Around 37% of total compensated employment in 2023 was informal. For ages 20–29, the rate exceeded 40%, reflecting young workers’ difficulty in accessing stable jobs. Employment rates for ages 15–24 were about 29%, below the OECD average of 43%.

The labor market is described as bifurcated: official workers have higher pay, stronger protections, and union voice, while the other group faces lower pay (30–40% less), fewer benefits, and limited mobility. Beyond pay, this polarization affects career opportunities and long-term stability.

Another consequence is increased work pressure on official workers. With fewer new hires, workloads rise for existing staff. Korean workers work about 1,865 hours per year on average, significantly above the OECD average and ahead of peers such as Japan, the United States, and Germany.

This creates a paradox: workers benefit from strong protections but also experience high work intensity.

Samsung as a case study

The article links these dynamics into a cause-and-effect chain. A stringent labor-law system discourages aggressive hiring and fragments the labor market. Fragmentation can raise inequality and pressure, which may erupt into labor conflicts.

In this framework, strict firing standards combined with expanding collective bargaining power reduce managerial flexibility. Meanwhile, rising semiconductor profits in 2024–2026—driven by data-center and AI demand—sharpen tensions over value distribution within firms.

At Samsung, the unionized share is around 90,000, or more than 70% of the group’s workforce in Korea, underscoring strong mobilization. Workers compare pay with rivals such as SK Hynix and seek compensation schemes tied to profitability. Requests for higher pay and changes to bonus policies—within a system where firms have limited ability to adjust headcount—have translated into direct conflict, raising the risk of a large-scale strike and threatening production in a globally integrated semiconductor supply chain.

Samsung, once associated with a non-union environment, is now at the center of labor disputes, illustrating that worker power can accumulate and surface when conditions align.

Policy trade-offs and the search for balance

Korea’s labor-market evolution is described as a swing of the “policy pendulum.” The system shifted from prioritizing growth through cheap labor toward protecting workers. The trade-off is that protecting workers can increase job stability but reduce market flexibility, potentially dampening incentives to create new jobs and making it harder for young people to enter formal employment.

Strong union rights can improve workers’ bargaining position but can also heighten tensions with employers. The central question is whether Korea can balance worker protection with growth incentives. Without adjustments, the labor market could remain more fragmented, more stressed, and less efficient, making events like Samsung’s labor disputes less exceptional and more characteristic of the economy.
