Samsung union threatens semiconductor production halt

The Samsung Group pan-industry labor union said it may halt semiconductor production and is voting on strike authorization, Choi Seung-ho, union head, told Reuters.

The vote began on March 9 and the union said turnout exceeded 70% by March 13.

Choi warned half of output at the Pyeongtaek plant could be affected, with an 18-day strike set to begin May 21 if approved.

The union said a strike could worsen global semiconductor shortages.

The dispute followed SK hynix removing its bonus cap and setting payouts at 10% of operating profits, which prompted Samsung union demands.

Samsung has said removing the bonus cap would make it difficult to secure funds for future investments and could foster a sense of relative deprivation among other employees.

Implications, context, and why it matters.

Samsung’s bonus formula puts workers at odds with company investment

The dispute focuses on Samsung’s bonus metric, Economic Value Added (EVA), a financial performance measure that can cut bonuses when the company spends heavily on capital investments 1.
Bonuses make up 30% to 50% of total pay, so many workers say the formula leaves them paying the price for long-term spending such as new facilities 1.
Employees in Samsung Electronics’ semiconductor (DS) division got no bonuses in 2023 after the unit posted a loss of about 15 trillion won 2.
The Samsung Group pan-industry labor union, Samsung Electronics branch, formed in 2019, wants to drop the complicated approach and tie bonuses to operating profit 3, 2.

The union’s strike threat faces internal and operational headwinds

The union’s influence looks smaller than its warnings, since a 2024 strike lost momentum and an internal scandal over alleged extra wage increases for some union officials led about 5,000 members to quit, according to one whistleblower 3.
Samsung says it will speed up automation in semiconductor production lines for health and safety. One analysis puts automation at nearly half of lines, 44%, with that share expected to rise and reduce disruption from events like strikes 4.
Even a brief slowdown could worsen a global memory shortage, with demand estimated at about three times the combined output of Samsung, SK hynix, and Micron 5.
The AI boom has pushed some large customers to negotiate supply deals reaching out to 2027 to lock in components 5.
