The Yellow Envelope Law: Korea's Labor Law Reform

Overview

On August 24, 2025, South Korea's National Assembly passed the amendment to the Trade Union and Labor Relations Adjustment Act, commonly known as the 'Yellow Envelope Law.' Passed with an overwhelming vote of 183 in favor and 3 against, this bill represents the culmination of 20 years of labor demands for strengthened constitutional rights regarding unionization, collective bargaining, and strikes.

Origin of the Name

The name "Yellow Envelope Law" originates from an event in 2014. When Ssangyong Motor workers faced massive damages claims for occupying a factory, citizens supported them by putting donations in yellow envelopes. This incident exposed the reality that workers' legitimate exercise of labor rights was being restricted by excessive damages claims, and it became a symbol of legal reform.

Key Provisions

1. Expanded Definition of Employer

The most fundamental change in the bill is the expanded definition of 'employer.'

• Before: Only companies with direct employment relationships qualified as employers
• After: Any entity that "substantially and concretely controls" working conditions is defined as an employer

This means subcontracted, dispatched, and platform workers can now negotiate with the parent company.

2. Expanded Scope of Labor Disputes

The scope of legally recognized union strikes has been significantly broadened.

• Before: Limited to working conditions such as wages and work hours
• After: Includes "management decisions that affect working conditions"

In other words, lawful strikes are now possible regarding corporate restructuring, overseas relocation, investment plans, and other management policies.

3. Limitations on Damages Liability

Excessive damages liability for unions and workers is restricted.

• When a union conducts a lawful strike, damages liability is limited to a scope proportionate to actual involvement
• This prevents the vicious cycle of workers being burdened with excessive damages for exercising legitimate rights

Implementation Schedule

• Passed by National Assembly: August 24, 2025
• Scheduled implementation: March 2026 (with a 6-month grace period)

Expected Effects and Significance

From the Workers' Perspective

• Strengthened labor rights: Fundamental labor rights demanded for 20 years
• Protection of non-regular workers: Expanded rights for vulnerable groups such as platform and dispatched workers
• Prevention of excessive damages: Preventing workers from going bankrupt due to legitimate exercise of rights

Social Significance

• Building an advanced labor law system that aligns with international labor standards (ILO)
• Improving unequal labor-management relations toward a more balanced direction

Concerns from Business and Government

Business Community Opposition

• Korea Employers Federation (KEF): Strong opposition, calling it "equivalent to requiring union consent for all business decisions"
• Investment contraction concerns: According to one survey, approximately one-third of foreign companies operating in Korea are considering reducing or withdrawing their investments

Key Business Concerns

1. Reduced corporate competitiveness: Delays and increased complexity in management decision-making
2. Investment avoidance: Choosing overseas investment due to increased business risk in Korea
3. Reduced employment: Potential decrease in corporate willingness to hire

International Context

This bill is part of Korea's efforts to adopt international labor standards as it joins the ranks of advanced nations. Many developed countries already guarantee similar levels of labor rights.

Outlook and Considerations

The Yellow Envelope Law is:

• Progressive perspective: A legitimate restoration of long-suppressed labor rights
• Conservative perspective: Excessive regulation that infringes on corporate management autonomy

Both sides have valid points, and during actual implementation, labor and management must strive to reach consensus and make adjustments for the best impact on the Korean economy.

Conclusion

The Yellow Envelope Law is not merely the passage of a bill — it signifies a fundamental change in Korea's labor-management relations. With implementation scheduled for March 2026, the critical challenge remains: how to balance the strengthening of workers' rights with corporate management autonomy.
