TLDR
- Samsung stock closed up 3.9% to 281,000 won on Monday after South Korea’s government intervened in labor talks
- Workers at Samsung’s chipmaking unit threatened an 18-day strike starting May 21 over bonus disputes
- The union wants 15% of annual operating profit set aside for bonuses and removal of a 50% salary cap
- JPMorgan estimates the strike could cut 21–31 trillion won from operating profit
- Samsung just reported record Q1 operating profit of 57.2 trillion won, driven by AI chip demand
Samsung Electronics posted record first-quarter operating profit of 57.2 trillion won, but a looming worker strike threatened to derail that momentum. The stock fell as much as 9.3% last week before rebounding 3.9% to 281,000 won on Monday.

The dispute centers on pay. Samsung’s largest union, representing over 45,000 workers, wants the company to set aside 15% of annual operating profit for a bonus pool. It also wants the removal of a 50% cap on annual salaries. Management has pushed back, arguing bonuses should be merit-based.
Workers at Samsung’s chipmaking unit were set to begin an 18-day strike on May 21 if talks failed. That deadline is what lit a fire under Seoul.
Prime Minister Kim Min-seok said over the weekend that a strike would cause “unprecedented economic damage.” He said Seoul would pursue all options, including emergency arbitration, to prevent it — a mechanism that would freeze industrial action for 30 days.
A South Korean court also threatened to fine the union around 100 million won ($66,500) per day if it defied orders not to strike.
President Lee Jae Myung added his voice too, posting on social media that management rights should be respected just as much as labor rights.
Why the Stakes Are So High
Samsung is not just any company. It accounts for 22.8% of South Korea’s total exports and 26% of the domestic stock market. A stoppage at its chip factories would ripple well beyond its own balance sheet.
Kim warned that a single day of shutdown at Samsung’s semiconductor facilities could cause direct losses of up to 1 trillion won — with broader damage potentially reaching 100 trillion won if materials had to be scrapped.
JPMorgan put numbers to the risk too, estimating the strike could shave 21 to 31 trillion won off operating profit, with sales losses of around 4.5 trillion won.
On Monday, Samsung and the union resumed government-mediated talks. National Labor Relations Commission Chairman Park Soo-geun confirmed talks would continue through Monday evening and pick back up Tuesday morning.
Record Profits Meet Labor Pressure
The timing is awkward. Samsung’s chip division alone generated 53.7 trillion won in operating profit in Q1. The company has also started selling HBM4 chips for Nvidia’s Vera Rubin platform and expects AI-related demand to stay strong.
The union’s push for a bigger cut of those gains is at the heart of the dispute. Workers argue that Samsung’s AI windfall — built in large part on their labor — hasn’t been shared fairly.
The KOSPI index gained just 0.3% on Monday, while Samsung’s 3.9% rise stood out. That gap tells you exactly what the market was reacting to.
As of Monday, the strike has not been called off. Talks are ongoing, with the May 21 deadline still in play.
