Union bonus demands, strike threats cast shadow over Korea's future

A growing push by unions to claim a fixed percentage of operating profit as bonuses — before companies can allocate earnings to investment or hiring — is raising alarm across the business community. Executives and analysts warn that the trend threatens to divert resources essential for employment, research and development, and long-term competitiveness, with consequences that could extend beyond individual companies to the national economy.

The Korea Employers Federation released a report Monday titled "Implications of Toyota's Labor-Management Relations," cautioning that domestic unions have increasingly shifted toward bargaining focused on short-term profit distribution rather than long-term survival and investment that would benefit both sides. "Excessive union demands for profit sharing could seriously erode the funding needed for R&D and future technology investment at a critical moment of industrial transformation," the federation said.

Demands that companies pay bonuses equivalent to a set percentage of operating profit or net profit have spread well beyond the semiconductor industry. Last year, the SK Hynix union fired the opening shot with its call for bonuses tied to a percentage of operating profit; the issue reached a peak this year during Samsung Electronics' wage and collective bargaining talks. Since then, similar demands have surfaced in wage negotiations across the automotive, shipbuilding, telecommunications and IT sectors.

The lowered threshold for strikes under the amended Labor Union Act — commonly known as the "Yellow Envelope Law" — has amplified the pressure, with the threat of large-scale collective action being used as leverage to win the profit-linked bonus demands. Under the law, companies seeking damages from strike activity must prove the degree of individual union members' liability on a case-by-case basis, making actual claims difficult to pursue. Analysts say the perceived effectiveness of strikes has grown further after the government stepped in directly to mediate during a threatened general strike at Samsung Electronics.

The surge in demands by subcontractor unions for direct negotiations with parent companies since the Yellow Envelope Law took effect has added another layer of instability to labor relations. According to the Ministry of Employment and Labor, in the first month after the law came into force, 1,011 subcontractor unions filed bargaining demands against 372 primary contractor workplaces, involving approximately 146,000 union members.

Disputes between labor and management over the scope of employer status and bargaining topics have multiplied as unions press for negotiations regardless of whether the parent company is formally recognized as an employer. Cases are also increasing in which subcontractor unions, following the lead of large conglomerate unions that have put profit-sharing on the bargaining table, are pressing parent companies for a share of earnings.

The Korea Employers Federation said some subcontractor unions have occupied workplaces and staged sit-in protests to pressure parent companies into bargaining, warning that labor unrest is set to intensify. "The Korean Confederation of Trade Unions has announced a general strike for July 15 and large-scale rallies by its affiliated organizations, citing the goal of winning direct negotiations with parent companies," the federation said, expressing concern that labor-management instability will worsen.

Excessive strikes and adversarial labor relations are also weighing on foreign investment. The European Chamber of Commerce in Korea and the American Chamber of Commerce in Korea both warned last year that the Yellow Envelope Law could prompt foreign companies to exit the Korean market.

Korea's labor relations continue to score poorly in international competitiveness assessments. In the IMD 2025 World Competitiveness Ranking, Korea placed 27th overall among 69 countries but ranked 53rd in the labor market category. In a survey of business executives worldwide, only 5.3 percent cited "effective labor-management relations" as an attractive feature of the Korean economy — the lowest-ranked factor among all factors measured.

"After the Samsung Electronics cross-enterprise union succeeded in securing the percentage-based bonus, other large conglomerate unions appear to be looking to use joint campaigns as momentum," a business community official said. "This kind of union movement, which holds the threat of strikes as a bargaining chip, will ultimately become a factor in the decline of corporate competitiveness."
