## Posco's 'Real Boss' Responsibility Debate: Will It Shake Up South Korea's Corporate Governance in 2026?
### [Background]
South Korea's economy has long been built on a subcontracting structure centered around large corporations. In this process, subcontracted workers have faced various problems such as job insecurity, low wages, and poor working conditions. Client companies have avoided legal responsibility through contractual relationships with subcontractors, and have been passive in protecting the rights and interests of subcontracted workers despite their substantial influence. This imbalance has deepened social inequality and has been pointed out as a major cause of solidifying polarization in the labor market. In particular, labor organizations, including the Korean Metal Workers' Union, have consistently emphasized the responsibility of large corporations as 'real bosses' and have demanded active intervention to resolve subcontracted labor issues. Although there have been similar cases in the past, it has been difficult to clearly identify legal responsibility, making it difficult to bring about substantial change. However, with the recent implementation of the 'Yellow Envelope Act' and the strengthening of the client company's duty to negotiate, signs of change are emerging in this situation. The Posco situation is expected to be an important opportunity to redefine the scope of responsibility of large corporations for subcontracted workers in this changing landscape.
### [Current Situation]
On April 9, 2026, local time, breaking news reported that Posco had begun individual negotiations with subcontracted labor unions. This is a follow-up measure to the Labor Relations Commission's recognition of Posco's 'client company as employer.' The Labor Relations Commission determined that Posco has a substantial influence on the working conditions of subcontracted workers and decided that Posco has a duty to negotiate. The negotiations will be held at Posco headquarters, and representatives from subcontracted labor unions and Posco officials will attend. The main agenda of the negotiations includes wage increases, job security, and improvement of working conditions, which are the demands of subcontracted workers. In particular, these negotiations are significant in that they are the first time that a large corporation has directly negotiated with a subcontracted labor union since the implementation of the 'Yellow Envelope Act.' The 'Yellow Envelope Act' contains provisions that limit companies' claims for damages for illegal labor disputes and strengthen the client company's duty to negotiate. Posco is expected to focus on resolving the grievances of subcontracted workers and stabilizing labor-management relations through these negotiations. However, difficulties are expected in the negotiation process, and there are predictions that it may take a considerable amount of time to reach an agreement. Meanwhile, the Korean Metal Workers' Union welcomed the negotiations but emphasized that Posco must engage in negotiations with a sincere attitude. The Korean Metal Workers' Union stated that it plans to continue to pressure Posco to accept the demands of subcontracted workers and make substantial improvements.
### [Multi-faceted Analysis]
Posco's individual negotiations with subcontracted labor unions are expected to have a wide-ranging impact on the entire South Korean corporate ecosystem, beyond a simple change in labor-management relations. First, from a market perspective, this decision may have a negative impact on Posco's stock price in the short term. This is because increased costs and the possibility of strikes during the negotiation process can dampen investor sentiment. However, there is also an analysis that it can have a positive effect in the long term. Improving the working conditions of subcontracted workers can lead to increased productivity, which can contribute to strengthening Posco's competitiveness. In addition, in a situation where social demands for ESG management are increasing, Posco's decision can enhance its corporate image and have a positive impact on attracting investment. From a social perspective, this decision can contribute to resolving inequality in the labor market. As the responsibility of large corporations for subcontracted workers is strengthened, the level of protection of the rights and interests of subcontracted workers is expected to improve. This can increase fairness throughout society and contribute to promoting social integration. From a political perspective, this decision can affect the government's labor policy. The government is expected to verify the effectiveness of the 'Yellow Envelope Act' through this case and refer to it in future labor-related legislation. In addition, this decision can deepen the labor policy debate in the political arena. The progressive camp is expected to welcome this decision and argue that the responsibility of large corporations should be further strengthened. On the other hand, the conservative camp is expected to raise concerns that it may infringe on the management autonomy of companies and argue for deregulation. Experts predict that this decision will bring about fundamental changes in the way large corporations manage subcontractors. Large corporations need to redefine their relationship with subcontractors as a win-win cooperation relationship, not just a contractual relationship. In addition, large corporations need to make various efforts, such as expanding investment to improve the working conditions of subcontracted workers and establishing fair trade practices with subcontractors.
### [Future Prospects]
The Posco situation is expected to bring about the following changes in South Korea's corporate governance in the future. First, the scope of responsibility of large corporations for subcontracted workers will be expanded. The court is more likely to make a ruling recognizing the responsibility of the client company in similar cases, referring to the Posco case. This will encourage large corporations to take a more active role in improving the working conditions of subcontracted workers. Second, the influence of the 'Yellow Envelope Act' will increase further. The 'Yellow Envelope Act' strengthens the client company's duty to negotiate and contains provisions that limit companies' claims for damages for illegal labor disputes. The Posco situation serves as a case that proves the effectiveness of the 'Yellow Envelope Act' and will have a significant impact on future labor-related legislation. Third, ESG management of companies will become more important. ESG management refers to a management method that considers the environment, society, and governance. The Posco situation will further strengthen social demands for corporate social responsibility and encourage companies to actively adopt ESG management. The points that readers should pay attention to are as follows. First, the outcome of negotiations between Posco and the subcontracted labor union. The outcome of the negotiations will be an important precedent for setting the relationship between large corporations and subcontracted labor unions. Second, the trend of court rulings. It is important whether the court will make a ruling recognizing the responsibility of the client company in similar cases. Third, changes in the government's labor policy. It is important to pay attention to how the government will verify the effectiveness of the 'Yellow Envelope Act' and what impact it will have on future labor-related legislation. From the perspective of AI, the Posco situation will be a catalyst for promoting the evolution of South Korea's corporate ecosystem. The old practices and unfair structures of the past can no longer be maintained, and companies must build a sustainable management model that fits the new era. Otherwise, they will be left behind.
