Samsung's $400,000 payout for memory workers sparks revolt as other divisions get only $4,000

At a glance:

• Memory division employees offered ~$400,000 bonuses, while DX division (smartphones, TVs) gets ~$4,000, sparking widespread internal backlash.
• Production slowdowns and decision-making freezes in foundry and packaging (TSP) units threaten HBM4 output for Nvidia's Rubin AI accelerators.
• Union ballots open May 23–27; non-memory DS division members could block ratification, prolonging operational disruption.

Deep internal rift over profit-sharing threatens Samsung's AI chip ambitions

A tentative profit-sharing agreement between Samsung's management and its largest labor union has averted an 18-day strike but has instead ignited a fierce internal conflict that is now disrupting critical operations. According to a report from Seoul Economic Daily, the deal has triggered meetings being canceled across non-memory and shared business units, with work negligence becoming widespread in the foundry and Test & Package (TSP) divisions. These back-end packaging and testing operations are essential for producing high-bandwidth memory (HBM), the advanced chips powering AI accelerators.

A source told the publication that "decision-making on major projects has come to a complete halt," as resentment deepens over a stark bonus disparity. The conflict puts at risk Samsung's ability to ramp up HBM4 production for Nvidia's next-generation Rubin AI accelerators. The TSP uses an integrated turnkey system routing chips through its own foundry and packaging lines; any slowdown in these back-end operations directly constrains HBM output. With all three major memory producers racing to fulfill hyperscaler orders, this internal strife could derail Samsung's competitive timeline.

Staggering payout gap fuels union backlash and legal threats

The root of the conflict is a massive disparity in proposed payouts. Under the tentative deal, memory division employees stand to receive bonuses of roughly 600 million won ($400,000). In contrast, workers in the DX (Device eXperience) division, which covers smartphones, TVs, and home appliances, would receive approximately 6 million won ($4,000). The deal allocates 10.5% of the semiconductor division's operating profit as stock-based bonuses, with an additional 1.5% in cash.

This inequity has provoked a fierce reaction. A smaller union representing DX employees filed a court injunction this week to block the larger, chip-dominated union from handling collective bargaining. That union's membership has surged from 3,000 to nearly 13,000 since the deal was announced. Separately, the Korea Shareholder Action Headquarters has threatened legal action, arguing the profit-linked bonus structure requires shareholder approval under Korean law. Electronic ballots for union members began on Friday, open through May 27, with ratification requiring participation from more than half of eligible members and a majority yes vote. Approximately 43,000 non-memory union members within the DS division could swing the outcome.

Production paralysis and strategic risk for Samsung's record year

Internal message boards have shown strong opposition from workers who view the deal as favoring the memory unit at everyone else's expense. The disruption in TSP is particularly consequential because it handles the essential back-end work for HBM. Another source warned that continued negligence on production and verification lines could damage Samsung's customer relationships and jeopardize delivery commitments, a critical concern as the industry races to secure HBM supply.

Samsung's semiconductor CEO, Jun Young-hyun, urged employees in an internal memo Thursday to move past the conflict. However, the dispute now poses a tangible risk to the company during what Bloomberg estimates will be a record year, with 2026 operating profit projected at 330 trillion won (~$218 billion). The work stoppages and decision-making paralysis in key divisions threaten to undermine Samsung's strategic push in the high-margin, high-demand AI memory market at a pivotal moment.

What to watch next

The outcome of the union ballot, which runs through May 27, will be critical. If the deal is rejected, Samsung could face renewed strike threats. Even if ratified, the deep-seated resentment may linger, potentially affecting collaboration between divisions. Investors and customers will closely monitor whether Samsung can quickly restore full functionality to its TSP operations and reassure partners like Nvidia that HBM4 supply timelines remain intact. The situation also highlights the growing tension within South Korea's chaebol system as lucrative AI-driven profits collide with long-standing labor expectations for equitable sharing.
