SK Hynix Inc. workers narrowly rejected a tentative wage and collective-bargaining agreement this week [2], [3].

The outcome leaves the South Korean chipmaker in a precarious position as it attempts to balance labor costs with record profits driven by the artificial intelligence boom. Because SK Hynix is a critical supplier of high-bandwidth memory for AI, prolonged labor instability could threaten production schedules.

The proposed agreement, announced Aug. 20, included a 6.3% salary increase [1]. Beyond the base pay hike, the deal sought to transition the company's bonus structure toward stock-based profit sharing rather than traditional cash payments [1], [4].

The production-worker union, which consists of 7,535 members [3], voted on the proposal between Aug. 25 and Aug. 26 [2], [5]. The rejection was close, with the deal failing by 25 votes [2].

Negotiations between the company and the union had initially appeared successful when the tentative deal was first publicized. However, the narrow margin of the vote suggests a deep divide among the workforce regarding the shift to stock-based compensation. Management and union leaders must now resume negotiations to reach a final agreement [4].

This labor dispute comes at a time of significant financial growth for the company. The demand for AI-memory chips has pushed SK Hynix toward record profits, leading workers to seek compensation that reflects the company's current market success [1], [4].

The rejection was close, with the deal failing by 25 votes.

The rejection of the wage deal underscores the tension between corporate efforts to align employee incentives with long-term stock performance and worker preferences for immediate cash liquidity. In the high-stakes AI hardware race, any disruption in South Korea's semiconductor labor force could create bottlenecks for global tech firms relying on SK Hynix for specialized memory chips.
