Samsung Electronics' South Korean union said it would stick to plans for an 18-day strike starting May 21, even after the company offered to resume pay talks without conditions. The dispute is fueled by frustration over performance bonuses, as rival SK Hynix has benefited from the AI-driven memory chip boom and removed its bonus cap. Samsung's union wants a more transparent profit-sharing system and a larger share of operating profit, raising concerns over possible disruption at the world's biggest memory chipmaker.
