Samsung Electronics faces a strike after wage talks collapsed on May 19, 2026, with nearly 48,000 workers planning an 18-day walkout starting May 21. The union said it would proceed despite last-minute, government-mediated negotiations.

Strike Plan and Scope

The planned walkout, described as Samsung’s worst-ever strike, involves nearly 48,000 workers set to halt production for 18 days beginning May 21. The dispute centers on bonus payouts. The union demands allocating 15% of operating profit to a performance-bonus pool and removing the current cap that limits bonuses to 50% of annual salary. Management has resisted permanent changes, proposing to maintain the existing bonus system while offering special incentives tied to market leadership. The scale and duration of the strike threaten significant disruption to Samsung’s device and semiconductor output and could affect global supply chains.

Negotiations and Market Reaction

Management and the union resumed government-mediated talks on May 19 but remained deadlocked on a key issue one day before the strike. After talks failed to produce a deal, the union confirmed it would proceed with the walkout. Following reports of the breakdown, Samsung’s shares fell nearly 4%, reflecting investor concern over potential production delays. Earlier marathon sessions, including a 17-hour meeting at the Central Labor Committee in Sejong, had already highlighted the intractability of the bonus dispute ahead of the strike.
