The Ministry of Employment and Labor will supplement its interpretation guidelines for the Yellow Envelope Law, rather than pursue a separate presidential decree, to clarify which management decisions can qualify as labor disputes. The Presidential Office said on the 28th that the guidance would be usable immediately at workplaces, while noting that a decree would require more than three months for proposed-rule notification and regulatory review. The government will monitor workplace developments and consider further measures if necessary. The law, implemented in March, broadened labor disputes to include business-management decisions affecting working conditions and clear violations of collective agreements. Uncertainty remains over issues including investment-related workplace reassignments and performance bonuses. The ministry had reviewed a decree after President Lee Jae-myung repeatedly instructed officials to establish specific standards, but concluded that the law contains no express delegation to subordinate legislation. Existing guidance will therefore be expanded with additional cases and explanations, including the view that an N% performance bonus based on operating profit would be difficult to treat as a labor-dispute subject. Labor and management are both expected to contest the guidance, while a labor law expert has said the underlying ambiguity cannot be fully resolved without amending the law.
