South Korea Passes Yellow Envelope Bill, Expanding Bargaining Rights and Limiting Strike Damage Claims

A new bargaining table for South Korea's workers

South Korea's National Assembly passed the Yellow Envelope Bill on August 24, 2025, with an overwhelming majority, setting up a major change in who must negotiate with workers and who can be held responsible for losses during strikes. The amendments to the Trade Union and Labor Relations Adjustment Act (TULRAA) are scheduled to take effect in March 2026.

As of August 29, subcontractor unions are already pressing large companies for direct negotiations. Workers at Hyundai Steel have demanded talks and the withdrawal of damage lawsuits, while a subcontractor union at Samsung Electronics has called for the company to intervene in a dispute over back pay. Similar activity has been reported at Naver, SK hynix and major department store chains.

The central change is straightforward: a company that substantially controls working conditions may have to bargain with the people doing the work, even when another business formally employs them. The law also broadens the scope of labor disputes and restricts employers' ability to seek damages from unions and individual workers.

For subcontracted, nonregular and platform workers, the legislation promises stronger protection in a labor market where employment arrangements often separate the company making decisions from the company signing employment contracts. For businesses, it creates concerns about responsibility for negotiations, disruption across supply chains and the boundaries of lawful strikes.

The passage follows a campaign lasting 20 years, failed legislative attempts and two presidential vetoes. President Lee Jae Myung's Democratic Party championed the measure. Labor organizations celebrated its approval, while business associations and conservative politicians opposed it.

Why yellow envelopes became a symbol

The bill takes its name from yellow envelopes that citizens used to send donations to SsangYong Motor workers facing substantial lawsuits after a strike in 2009. The donations became a public campaign against the financial hardship imposed on workers and their families.

The dispute followed the loss of more than 2,600 jobs at SsangYong Motor. The union faced lawsuits seeking more than 300 billion won, making the confrontation a national flashpoint over the use of civil damage claims against striking workers.

The roots of the campaign reach further back. In the 1990s, a government directive encouraged companies to use civil lawsuits against striking workers. A wave of damage claims followed, leaving many union members facing financial ruin. The SsangYong dispute brought that problem into wider public view and helped mobilize support for changes to the law.

The main stages leading to the August vote were:

• In the 1990s, a government directive encouraged civil lawsuits against striking workers.
• In 2009, the SsangYong Motor strike and damage claims prompted the public donation campaign associated with yellow envelopes.
• During the subsequent legislative effort, proposals failed and two presidential vetoes blocked passage.
• On August 24, 2025, the National Assembly approved the amendments with an overwhelming majority.
• In March 2026, the law is scheduled to take effect after a transition period of six months.

The nickname connects the new bargaining rules to the issue that first drew public attention: whether workers taking collective action should face debts large enough to overwhelm their households.

Who counts as an employer or employee?

The legislation changes Articles 2 and 3 of TULRAA. One of its most consequential provisions broadens the definition of an employer beyond the business that directly hires a worker. An entity exercising substantial and specific control over duties or working conditions can also be responsible for labor negotiations.

Previously, the obligation to bargain rested with direct employers. Under the new approach, a parent company may be required to negotiate with a subcontractor's union when it determines key employment conditions, even without a direct contractual relationship with those workers.

A subcontractor is a business hired to perform work for another company. That arrangement can leave workers negotiating with a smaller firm while a larger company controls important parts of the work. The amendment seeks to bring the company with that control to the bargaining table.

The definition of an employee also expands to include anyone who provides labor for another business or organizes or joins a union. This explicitly covers platform workers, freelancers and people who are self employed, groups that have historically fallen outside traditional labor protections.

These changes are especially relevant to shipbuilding, logistics, manufacturing and the growing platform economy. Across those industries, the legal question becomes who actually controls the conditions under which people work, alongside who formally employs them.

What direct negotiations could change

Shipbuilding illustrates the problem the legislation addresses. Dozens of subcontractors can operate within the shipyards of a single conglomerate. Workers may be employed by those smaller companies while the parent company dictates key terms affecting their employment.

Under the new law, the parent company must come to the bargaining table if its control meets the substantial and specific standard. That gives subcontractor unions a route to negotiate with the business making decisions that their immediate employer may have limited power to change.

Large conglomerates have been able to set wages and safety standards while outsourcing work to smaller firms. The amendments are intended to connect that practical influence with responsibility for negotiations. Direct bargaining could give workers a clearer route to raise pay, safety and working conditions with the company that controls them.

Platform work presents a related issue. Delivery drivers and other participants in the gig economy may have their earnings and assignments shaped by a company's pay algorithms and dispatch systems. An algorithm is a set of computer instructions that can determine matters such as how jobs are allocated or payments calculated.

The expanded protections allow those workers to demand talks with companies controlling those systems. The practical reach extends beyond traditional factory employment to businesses relying on flexible work arrangements and workers without regular employment status.

Courts will need to determine what substantial and specific control means in individual cases. The standard may operate differently across industries and employment arrangements, making the details of control central to future disputes.

Which disputes can lead to strikes?

The bill broadens the definition of a labor dispute beyond wages and working hours. Managerial decisions such as restructuring, mass layoffs, plant relocations and business closures can now fall within its scope.

Strikes against those decisions, previously regarded as illegal, are recognized as legitimate industrial action under the changes. This matters particularly to workers in insecure employment, who can face sudden changes in their jobs when a company reorganizes or shuts an operation.

A dispute over a closure concerns more than a wage increase. It can determine whether people have jobs at all and where they must work. Including such decisions in labor disputes gives workers a stronger basis for collective action over the future of their employment.

The legislation also ends the practice of peace obligations, which previously prevented unions from striking over issues covered by collective agreements. A collective agreement is an arrangement negotiated between an employer and a union covering employment terms.

Under the new rules, unions can strike when they disagree with how those agreements are interpreted or implemented. The change therefore reaches both new management decisions and disputes about whether existing promises are being carried out.

Business groups fear the broader definition will bring virtually all managerial decisions into the scope of strike action. Their concern is that decisions about production, staffing and investment could become harder to make when a wider range of disagreements can trigger industrial action.

How damage claims would be restricted

Companies' ability to bring large lawsuits against unions and individual workers is another central part of the amendments. Under the previous system, employers could seek compensation for losses incurred during strikes, exposing workers to substantial personal financial risk.

The Yellow Envelope Bill prohibits damage claims intended to threaten or obstruct unions. It also requires courts to consider proportionality, individual roles and financial circumstances before awarding damages. Proportionality means weighing a person's responsibility and circumstances when deciding the amount they should pay.

Responsibility among individual workers can be allocated only when there is concrete evidence of fault. That makes the actions of each person relevant to liability, rather than treating participation in a dispute as sufficient grounds for assigning the same burden to everyone.

The legislation introduces a self defense principle as well. Damages can be waived if a strike was the only means of protecting workers from unlawful conduct by their employer. This provision addresses circumstances in which collective action responds to an employer's own violation of the law.

Unions and workers will still face possible liability, but the restrictions raise the bar for employer lawsuits and reduce the risk of financial ruin. For workers considering industrial action, the change affects the potential personal cost of joining a strike.

The relationship between bargaining rights and damage claims is central to the reform. Workers gain a wider route to negotiate with companies controlling their conditions, while employers face tighter limits on using compensation demands against collective action.

Unions are already pressing their demands

Hyundai Steel's unionized subcontractor workers have staged protests demanding direct negotiations and the withdrawal of damage suits. At Samsung Electronics, a subcontractor union has asked the technology company to intervene over back pay, meaning wages that workers say should already have been paid.

Naver's IT operations show how the campaign reaches through several layers of corporate ownership. Unions representing workers at its sub-subsidiaries have held rallies demanding negotiations with management. Similar actions at SK hynix and major department store chains show that the pressure extends across technology, manufacturing and retail.

The Korean Confederation of Trade Unions described the passage as a historic achievement for workers' rights and connected it to the long campaign behind the legislation:

the result of two decades of activist sacrifices

Labor groups see the law as a correction to longstanding differences in bargaining power. Their immediate demands concern concrete workplace issues, including unpaid wages, access to negotiations and the financial burden of existing damage claims.

The timing matters. These demands are being made during the transition before the law takes effect in March 2026. Unions are already using its passage to press companies to engage with workers whose employment arrangements have previously placed them outside direct negotiations.

Why businesses and foreign investors object

Six major industry associations, including the Korea Enterprises Federation and the Korea Chamber of Commerce and Industry, issued a joint statement condemning the bill. They argue that the expanded employer definition could complicate disputes and disrupt workplace order.

Businesses also warn that uncertainty over the new rules could stall corporate decisions, especially where supply chains involve many contractors. Rising labor costs and delays, they say, could weaken South Korea's competitiveness in manufacturing, automobiles, shipbuilding and steel.

Small and medium enterprises are particularly anxious because many operate as subcontractors themselves. Their production schedules are often linked closely to those of other suppliers and larger customers. A strike at one supplier could disrupt work across that connected chain.

Some business leaders argue that ambiguity over which companies qualify as employers could produce confusion and unintended consequences. A central concern is how several companies sharing influence over work would manage demands for negotiations.

The American Chamber of Commerce in Korea (AMCHAM) has also raised concerns. James Kim, its chairman and chief executive officer, linked the debate to South Korea's position as a destination for business:

a flexible labor environment is essential to strengthening Korea's competitiveness as a business hub in the Asia-Pacific region.

Some multinational companies, including GM Korea, have hinted at reassessing their operations in the country if the business environment becomes less predictable. For those businesses, the debate concerns investment and operating decisions as well as the handling of individual workplace disputes.

What the government plans before March 2026

The government has announced a transition period of six months to prepare for the changes. A task force bringing together labor, business and government representatives will gather workplace feedback and develop guidance on the definitions of employer and labor dispute.

The task force will also provide support at workplaces for bargaining in industries with several layers of employment and contracting. Its planned responsibilities include monitoring compliance, enforcing the rules and investigating unlawful labor practices.

The Ministry of Labor plans to test joint bargaining models in sectors such as shipbuilding. The aim is to protect subcontracted workers while maintaining industrial competitiveness, giving workplaces practical arrangements for negotiations before disputes intensify.

The law puts into legislation trends already emerging in Korean courts, which have increasingly recognized the rights of workers in special employment arrangements and platform workers to organize and bargain collectively. It provides a common legal framework while leaving new questions for courts to resolve.

The scope of substantial and specific control remains to be determined in practice. Companies and unions will need guidance on when a parent company has enough influence over working conditions to carry a bargaining obligation. March 2026 is the next stated milestone for the law's implementation.

What the reform means for the labor divide

South Korea's labor market has a sharp divide between regular employees at large conglomerates and workers in less secure arrangements. Regular employees often have job security, higher wages and strong unions. Subcontracted, nonregular and platform workers face lower pay, weaker representation and limited legal protection.

The Yellow Envelope Bill aims to narrow that gap by strengthening workers' ability to exercise their constitutional rights to organize, bargain and strike regardless of employment type. Its practical focus is on access to the companies controlling work and protection from excessive financial claims.

Clearer bargaining arrangements and limits on lawsuits could reduce reliance on confrontational tactics that have long shaped South Korean labor relations. The transition also carries a risk of more industrial action and legal disputes as employers, unions and courts test the new responsibilities.

Other countries dealing with platform work and insecure employment are watching the changes. The explicit inclusion of platform workers and restrictions on corporate damage claims could influence labor policy debates elsewhere.

For South Korea, the immediate task is implementation: turning wider legal rights into workable negotiations while addressing businesses' concerns about disruption and uncertainty. The central test will be whether the reform reduces the entrenched divide between workers while maintaining industrial stability.
