Samsung Union Authorizes Massive 18-Day Strike at Memory-Chip Plants

Key Facts

1Samsung's union authorized an 18-day strike involving over 47,000 workers after mediation talks on bonuses collapsed.
2The union demands 15% of operating profit for bonuses, while management offered a 10% profit-sharing pool.

Samsung's primary labor union has authorized a comprehensive 18-day strike involving more than 47,000 workers following the collapse of mediation talks regarding annual bonuses. The union is demanding that 15% of operating profits be allocated to bonuses, while management has maintained an offer of only 10%, leading to a total breakdown in negotiations.

This escalation occurs at a critical juncture for the semiconductor industry as Samsung faces intense competition from SK Hynix, which recently reported robust growth in high-bandwidth memory (HBM) profits. Per market data, investors are closely monitoring the potential disruption to global supply chains, given Samsung's status as the world's largest memory-chip maker; the KOSPI index has already declined by 1% in response to the news.

Looking ahead, traders are assessing the impact of production halts on South Korean chip output.
