Profit-Linked Bonus Demands Spread Across South Korea’s Top Industries

Labor disputes are flaring simultaneously at some of South Korea’s flagship companies, spanning semiconductors, autos, biotech and telecommunications, as unions push for bigger, profit-linked bonuses. The Samsung Electronics union has warned of a general strike while demanding the removal of a bonus cap and distribution of 15% of operating profit. The Samsung Biologics union began its first full-scale strike since the company’s founding on May 1. The Hyundai Motor union is seeking bonuses equal to 30% of net profit, and the LG Uplus union is also demanding 30% of operating profit, widening what has become a contest over “profit-linked bonuses” across industry.

Unions argue that stronger results justify a larger share. But the demands are increasingly seen as going beyond routine pay bargaining, as signals emerge that could affect companies’ capacity to invest, production stability, supply-chain confidence, gaps between prime contractors and suppliers, and ultimately national industrial competitiveness.

Some in the industry trace the current dynamic to SK hynix, where bonuses around 10% of operating profit have come to be treated as a benchmark. Once a higher ratio is set at one company, other unions find it harder to accept less, and negotiations can shift from productivity to symbolic one-upmanship — a dynamic often described as a “bonus chicken game.” 

The issue is not confined to individual companies. Since the implementation of the so-called Yellow Envelope Act, bargaining demands by subcontractor unions toward prime contractors have surged, with requests filed at multiple worksites — including Hanwha Ocean, POSCO and Hyundai Motor — from the first day of enforcement.

As large-company unions raise profit-linked compensation standards, prime contractors’ cost burdens grow, increasing the likelihood that pressure is passed on through tighter supplier pricing or reduced investment.

That, in turn, highlights a long-standing bottleneck in Korean industry: bargaining power rises for regular workers at big firms, while smaller suppliers, nonregular workers and subcontracted labor can face greater instability. As bonus payouts grow, companies may have less room to raise payments to partner firms, potentially widening wage gaps between large companies and small and midsize businesses. Critics warn that what appears to expand labor’s share could deepen the labor market’s dual structure.

The industrial reality is unforgiving. Semiconductors, biotech and autos face global competition, heavy capital spending and pressure to shift technologies. If bonuses harden into an automatic fixed share of profits rather than rewards tied to productivity gains, management can become locked into short-term cash distribution while investment is pushed back.

When unions seek to maximize payouts based on short-term performance, spending on research and development, facility expansion and new businesses — often the first sources of future growth — is more likely to be squeezed.

The need now, the article argues, is not escalation but a reset of rules. Bonus systems should reflect more than a simple share of operating or net profit, incorporating investment execution, cash flow, industry cycles and future cost provisions. Before strikes and all-out confrontation, labor and management should institutionalize bonus formulas, upper and lower limits, and adjustment principles for downturns. It also calls for broader discussion of how compensation systems at major prime contractors ripple through suppliers and the wider industrial ecosystem.

South Korea’s economy rests on exports, manufacturing and the competitiveness of advanced industries. The current bonus conflicts are both a dispute over labor’s fair share and a warning light that could erode the power of the country’s growth engine.

Just as unions should weigh not only today’s profits but also tomorrow’s survival, companies should treat labor not simply as a cost but as a pillar of sustainable competitiveness.

The article concludes that this is not a problem that ends with one side’s victory. It says negotiations should focus on sustainability — not a test of strength — so that sharing industrial gains does not damage the industry’s future.
