Key parties include the Supreme Court (e.g., Second Division led by Chief Justice Oh Kyung-mi; First Division by Justice Ma Yong-ju), companies such as Samsung Electronics affiliate (Company S), SK Hynix, and others via labor unions; former employees and retirees as plaintiffs; and law firms like Shin & Kim, Kim & Chang, Ius Laboris.[1][2][3][4][6][7] Legislation centers on the Labor Standards Act, defining wages as regular payments directly tied to labor provision, quantity, or quality.[1][2][6]
These rulings build on Supreme Court precedents from December 2024 and 2025 (e.g., 2023Da216777, 2020Da219454), which distinguished performance-based pay without minimum guarantees or tied to continuous employment.[1][5] Paid regularly via employment rules or practices, they arose from employee claims for higher severance.[3][4][7]
The decisions are newsworthy due to their immediate impact on large corporations' costs—increasing severance burdens if bonuses count as wages (e.g., Samsung's tens-of-millions-won incentives)—and as benchmarks for pending cases later in February 2026, providing clearer criteria amid ongoing disputes.[1][2][4][6][8]
