Union members at Micron’s Taoyuan site in Taiwan will walk out on Thursday, Oct 22, after negotiations over profit sharing ran aground. The union announced the action on Monday and has not set an end date, promising more detail on the day.
The date matters because it collides with mediation between the company and a second union representing workers at Taichung, its largest site on the island.
Where the money argument sits
In a ballot running from Oct 1 to 6, 1,994 of the Taoyuan union’s 2,258 members backed a strike. The dispute is over bonuses rather than base pay: the unions want 15 percent of operating profit routed into quarterly employee payments.
Both Samsung and SK hynix already tie bonuses to company results, and Samsung faced its own strike threat this year over payouts. Micron has countered with a package worth 35 to 68 months of salary for its roughly 15,000 Taiwan employees, disclosed in September. Mediation in Taoyuan ended that month without agreement, and the company has described the package as separate from the dispute.
Why a bonus fight matters to buyers
Taiwan is where Micron builds the DRAM and high-bandwidth memory that goes into AI accelerators, a segment already squeezed by capacity limits and rising contract prices. President Lai Ching-te used the opening of the Taichung plant last week to press both sides toward good-faith talks.
A one-day stoppage will not clear a fab. The risk is what follows it. Micron’s Taiwanese workforce is its most exposed to competitor poaching, and the industry has spent two years competing on pay after Samsung’s own bonus revolt. If the walkout hardens positions ahead of quarterly results, retention becomes a cost item on top of an already tight supply equation.
