New guidelines on ‘Yellow Envelope Law’ rekindle dispute between labor, business

Sharp differences have emerged between business groups and labor unions following the government’s release of new guidelines on the so-called “Yellow Envelope Law,” a measure intended to protect striking workers from crippling liability lawsuits.

Historically symbolized by the yellow envelopes of cash donations used to support penalized workers, the revised law has drawn warnings from business leaders that it could embolden unions and disrupt operations.

The Ministry of Employment and Labor announced the new guidelines on Friday, ahead of its implementation on March 10 next year. It clarifies that subcontracted workers are entitled to collective bargaining rights with a main contractor if the contractor exercises structural control over their working hours or work methods.

Labor groups have criticized the guidelines for imposing stricter standards that reduce the liability of main contractors, while business associations warned that vague criteria could sow confusion on the ground and heighten uncertainties for management.

The law is a landmark revision that expands the definition of employers and the scope of labor disputes while limiting companies’ ability to seek large-scale damage claims against workers engaged in strikes.

Under the new guidelines, structural control is presented as the key standard for determining employer responsibility.

A main contractor may be recognized as an employer if it structurally constrains decisions on subcontracted workers’ labor conditions, such as working or rest hours or the number of workers required for specific processes.

The guidelines also state that business management decisions — including factory expansions, overseas investments, mergers, spin-offs, transfers or sales — do not automatically fall under collective bargaining. However, if such decisions are accompanied by layoffs or restructuring that result in concrete and substantive changes to employment statuses or working conditions, they may become subject to collective bargaining.

Labor groups argue that the new interpretation could undermine the intent of the revised labor law.

The Federation of Korean Trade Unions (FKTU) said in a statement the same day that the guidelines risk limiting employer responsibility and narrowing the substantive scope of labor disputes.

“If the labor ministry seeks to uphold the purpose of the revision, it should not use the abstract concept of structural control to restrict employer liability, but instead redefine the standard to more clearly reflect the real influence prime contractors exert in practice,” an FKTU spokesperson said.

The guidelines were also criticized for setting overly narrow standards for determining which labor disputes qualify as subjects of collective bargaining.

The Korean Confederation of Trade Unions argued that unions often cannot easily foresee whether management decisions will result in layoffs or restructuring, and noted that employers are not legally obligated to accept union demands even when an issue is open to bargaining. It added that there is little reason to strictly draw lines over what qualifies as a bargaining issue.

Meanwhile, business lobby groups, including the Korea Enterprises Federation (KEF), argued that the guidelines are overly broad, calling for clearer standards to prevent confusion in the workplace.

KEF warned that citing the potential termination of subcontractor or consignment contracts for noncompliance could be misunderstood as constituting structural control.

It argued that even routine contract terminations stemming from standard breaches could be misinterpreted as evidence of employer liability, potentially broadening the definition of “employer” to encompass ordinary contract management practices common in subcontracting arrangements.

The federation also raised concerns over the guidelines’ expanded treatment of labor safety and labor dispute issues, arguing that the government’s interpretation of “effective control” is dangerously elastic. By holding main contractors liable for safety systems regardless of specific statutory limits, the federation warns, the state is creating a broad new theater of legal risks under the Occupational Safety and Health Act.

“Contrary to the ministry’s stated intent, the guidelines could be interpreted to mean that a prime contractor’s legally mandated safety obligations toward subcontracted workers alone are sufficient to establish employer status, adding to uncertainty for companies operating complex subcontracting structures,” a KEF official said.

The labor ministry said it will gather broad input from labor and business groups as well as experts during the public comment period and actively reflect reasonable suggestions in the final guidelines.
