Transparent Profit-Sharing Boosts Staff Retention at SK hynix as Samsung Navigates AI Boom Challenges
As the global artificial intelligence (AI) boom propels demand for advanced semiconductors, two of the world’s leading memory chipmakers find themselves on vastly different trajectories regarding staff retention.
A recent study by corporate research firm Leaders Index revealed a stark contrast: by 2024, SK hynix’s staff turnover rate had dropped to approximately 1 percent. In sharp contrast, its fierce rival, Samsung Electronics, experienced a staff loss rate exceeding 10 times that figure.
This disparity in employee retention can partly be attributed to the companies’ operational scope. While both are pivotal memory chip producers within the semiconductor industry, Samsung’s business encompasses a much broader portfolio. Beyond diverse chip offerings, it manufactures a wide range of consumer electronics, from mobile phones and televisions to home appliances like refrigerators.
However, a more significant factor influencing this divergence lies in each company’s strategy for distributing the substantial financial windfall generated by the AI surge to its employees.
SK hynix specifically saw its combined staff turnover and resignation rate decrease from 2.4 percent in 2022 to a remarkable 1.3 percent by 2024, positioning it as the second-lowest among the 108 large corporations analyzed.
This generosity from SK hynix was well-founded. As a trailblazer in high-bandwidth memory (HBM) – the critical advanced chips indispensable for modern AI processors – the company achieved an impressive operating profit of 21.3 trillion won in 2024, equivalent to approximately $15.8 billion.
While Samsung’s employee turnover rate also saw a reduction, from 12.9 percent to 10.1 percent, it consistently remained in double digits. The Leaders Index study encompassed companies within Korea’s top 500 by revenue that submitted comparable sustainability reports between 2022 and 2024.
These positive staff retention figures for SK hynix through 2024 directly correlate with a significant reform: tying employee bonuses directly to operating profit and instituting a transparent payout formula. This strategy provided employees with a compelling incentive for loyalty, further aided by a general cooling in the job market.
Since then, employee compensation at SK hynix has escalated further, mirroring the company’s exceptional performance. In a landmark agreement in September 2025, SK hynix and its union eliminated the previous cap of 1,000 percent of base salary on profit-sharing, committing to allocate a full 10 percent of operating profit directly into the employee bonus pool.
This robust strategy coincided with SK hynix recording historic revenues of 97.15 trillion won and an unprecedented operating profit of 47.21 trillion won that same year. In February, news outlets widely confirmed the tangible outcome: a 2025 profit-sharing payout averaging an astonishing 2,964 percent of base salary for employees.
Conversely, Samsung’s journey through the same AI-driven boom has proven more contentious. Just days prior to a potential 18-day walkout by approximately 48,000 unionized workers, the company reached a tentative agreement last Wednesday, facilitated by government mediation. This agreement introduces an uncapped special bonus for its critical Device Solutions division – responsible for chip production – to be funded by 10.5 percent of agreed business results and disbursed in stock. Should union members approve this deal, currently under vote, it aims to bridge the significant employee bonus gap with SK hynix that had previously escalated unrest.
It’s important to note a significant caveat in this comparison: Samsung’s reported staff turnover rate encompasses its entire global workforce, not solely its semiconductor division. While Leaders Index specifically requested figures for the Device Solutions division, Samsung opted not to provide this data, thereby preventing a direct, apples-to-apples comparison within the critical chip sector.
