Strengthening Worker Protections: South Korea’s Yellow Envelope Act

At a time when some regions are stepping back from their commitments to human rights and ESG priorities, South Korea is taking a significant step forward. The new Yellow Envelope Act, set to take effect in March 2026, marks a landmark reform in labour and trade union law—particularly for industries that rely heavily on subcontracted, agency, or migrant workers.

Key provisions of the Act include:
• An expanded definition of “employer,” broadening accountability across complex supply chains.
• Broader protection of lawful industrial action, strengthening workers’ rights to organize.
• Safeguards against excessive corporate damage claims related to strikes or collective action.
• Increased relevance and protection for migrant workers, who make up a vital part of the labour force in many sectors.

These changes will have far-reaching implications for supply-chain compliance, labour practices, and corporate responsibility. More information is also available here.
