Eleven officials, two observations of scale

The action that began at 09:00 on Thursday was, in physical terms, small. Eleven union officials began the strike outside Micron's Taoyuan plant, per Taiwan's Central News Agency (CNA), after negotiations held at Taoyuan City government on Wednesday produced no agreement. AFP's reporter at the scene saw five striking workers gathered outside the plant as the action began, beneath a banner reading: "Micron failed to propose a profit-sharing scheme. The Taoyuan union will immediately begin strike action." The two counts describe different observations: 11 officials participating in the action, and five workers seen at the gate at that moment. Neither is a walkout by the plant's roughly 3,000 employees, most of whom were inside, where the company was holding a conference call with hundreds of staff.

The mandate behind those officials is not small. In the strike-authorisation ballot reported by CNA on 7 October, 2,012 of 2,258 eligible members cast ballots: 1,994 in favour, 14 opposed, 4 invalid. That is 99% of the ballots cast and 88.3% of every eligible member. Union chairman Jerry Lin told reporters the Taoyuan union had not given up and that talks with the company would continue on Friday.

Two formulas, not a formula and a package

The dispute is often summarised as a permanent formula against a one-off reward. That stopped being accurate on Thursday, when Micron announced a formula of its own.

The union's demand, as Reuters reports it, is a transparent system allocating 15% of Micron's operating profit to employees globally: a standing percentage, on a published base, paid quarterly from fiscal 2027. Alongside it, the unions sought a one-off bonus for fiscal 2026 that they put at about 83 months of salary for each Taiwan-based employee. Their objection to the existing Incentive Pay Plan is that Micron has not fully explained how its company-performance metric is calculated, and that it appears to track revenue growth more closely than profit.

Micron's answer is also a formula, but a different one. From fiscal 2027, a new quarterly bonus will supplement the annual incentive programme for employees worldwide. Its pool is calculated from profit after tax minus projected capital spending for the next quarter, with fiscal 2026 as the baseline. Half is paid in cash after results; half is paid in shares that vest after one year. Micron did not disclose a fixed share of earnings, or a total amount reserved for employees. The capital-spending deduction is the load-bearing detail: in years when Micron is building capacity aggressively, projected investment comes off the pool before employees are paid, so the bonus can shrink even while underlying earnings rise.

Around the formula, Micron raised the maximum payment under its annual incentive plan and announced Taiwan-specific measures: employer retirement contributions rising to 10% from 8%, three extra paid days off, higher shift allowances (the day-shift monthly allowance rises to NT$4,500 from NT$1,500 on 1 December 2026) and structural salary adjustments. Separately, the fiscal 2026 package announced in September remains on the table: compensation Micron described as equivalent to 35 to 68 months of base salary for Taiwan production workers, depending on eligibility and components, including a one-off NT$1 million (about US$31,000) appreciation bonus and equity awards. It is a described package equivalent, not a guaranteed payment to every employee.

So the dispute covers both immediate compensation and the longer-term formula. The permanent allocation is the more consequential unresolved issue, because it decides who shares automatically in the next AI cycle, and on whose arithmetic.

The denominators are not the same

The percentages in this dispute are routinely quoted side by side. They do not have the same base:

  • The Taoyuan demand: 15% of Micron's global operating profit, for employees globally.
  • Samsung Electronics: 10.5% of its semiconductor division's operating profit, reserved for special bonuses and subject to profitability targets, agreed in May to avert a planned strike.
  • SK hynix: 10% of annual operating profit allocated to an employee bonus pool, with a cap on payouts removed, agreed last year.
  • Micron's new plan: no fixed percentage; a quarterly pool from after-tax profit less projected capital spending, measured against a fiscal 2026 baseline.

Taiwan's unions cite the Korean arrangements as the standard their pay has fallen behind. Read as negotiating reference points, that is fair. Read as comparable payout rates, it is not: the profit bases, the eligibility conditions and the payment structures all differ, and Micron's quarterly plan is another calculation again, without the fixed 15% allocation.

One plant settled, on undisclosed terms

The most useful comparison sits inside Micron itself. On Wednesday, the day before the Taoyuan action, Micron and the union at its larger Taichung operation, where about 12,300 of its roughly 15,000 Taiwan employees work, announced a labour-management agreement covering multiple issues and withdrew from a mediation session scheduled for Thursday.

Neither side disclosed the terms; the joint statement said each side would communicate details to affected employees in the coming days. That silence limits what the settlement can prove. It shows Micron will sign an agreement. It cannot show whether Taichung accepted less than 15%, or received similar terms privately, because the two unions' outcomes cannot be compared from the public record.

What to watch, and what not to claim yet

Taiwan matters here because of concentration. Micron employs about 15,000 people on the island, and its sites there produce DRAM and high-bandwidth memory for AI servers at a moment when memory supply is tight enough that customers plan around it. A broader or prolonged stoppage would raise real supply questions. Thursday's action does not, on the reporting available: no production loss attributable to the strike had been verified in the reporting reviewed as of publication, and a one-day action by union officials is not a supply event.

The immediate question is narrower. The Taoyuan union said it planned to ask its members to vote on Micron's latest proposal. Whether members judge the new quarterly formula sufficient for the union to resume negotiations, or to end the action, is the next test. Micron Taiwan chairman Lu Dong-hui called the strike decision "regrettable" and said the company remained fully committed to continuing sincere communications. The strike ends, on schedule, at 09:00 on Friday. The argument over the formula does not.
