The Revised Yellow Envelope Act Is Now in Effect: The First Thing You Need to Check
Key Changes to Articles 2 and 3 of the Labor Union Act (Yellow Envelope Act)
“Does this mean our company could now be held responsible for issues involving subcontractor employees?”
This is a question increasingly being raised in real business environments.
The revised Yellow Envelope Act, which took effect on March 10, 2026, is not merely a technical amendment to statutory language. It represents a major institutional shift that strengthens the authority of labor unions and fundamentally redefines the scope of employers’ responsibilities.
The key changes introduced by the amendment include:
- Substantial expansion of the definition of “employer”
- Expansion of the scope of recognized labor disputes
- New grounds for reducing or limiting damages claims against labor unions
Ultimately, the core implication is clear: labor unions now possess broader bargaining power, while companies face increased legal responsibility.
As a result, companies must comprehensively review their contractual structures and internal decision-making processes, while labor unions must prepare lawful response strategies aligned with their newly expanded authority.
The extent of advance preparation will ultimately determine the scale of future legal risk. The following response measures therefore deserve close attention.
Key Response Points for Companies and Labor Unions
Through this amendment, the scope for recognizing a principal contractor as an employer has broadened significantly, while limitations on damages claims have substantially changed the landscape of labor-management relations.
From the corporate perspective, companies must carefully assess the extent to which they exercise control over working conditions within indirect employment structures such as subcontracting and outsourcing arrangements.
If a principal contractor substantially influences employees’ working conditions, bargaining obligations may arise. Accordingly, companies may need to revise contractual provisions and approval procedures.
In workplaces where multiple labor unions exist, it is also essential to establish strategies for responding to successive bargaining requests.
To address these issues, companies should establish:
- Standards for unified bargaining channels
- Internal information disclosure procedures
- Response systems for damages claims arising from lawful labor disputes
From the labor union perspective, direct bargaining channels with principal contractors are becoming more accessible, and the burden of damages liability during lawful labor disputes has been reduced.
As a result, the legality of bargaining procedures and the efficiency of organizational strategies have become increasingly important.
In essence, the amendment establishes a new standard for both labor and management: “clear responsibility and transparent procedures.”
Whether adequate preparation is undertaken now will become the most important factor in determining future dispute risks.
