May is typically labor unrest season in South Korea, but this year the epicenter of disputes is no longer traditional factories — it is high tech.
The bonus bonanza at the country's two chipmakers, which rode the AI wave to become two of only three Korean companies valued at more than US$1 trillion, is spilling across industries.
Employees from manufacturers to platform operators and biotech firms are demanding a greater share of record earnings, even as median wages for ordinary salary earners remain largely stagnant in Korea, exposing widening tensions over compensation, contribution and corporate inequality across the country's industrial landscape.
For decades, South Korea's export-driven economy operated on a form of "trickle-down" growth, in which profits generated by large conglomerates flowed through layers of suppliers, subcontractors and smaller manufacturers. Now, workers and industry officials warn that conflicts surrounding AI-era bonuses may be creating a different kind of trickle-down effect — one driven not by shared prosperity, but by widening pay gaps, internal resentment and intensifying labor tensions.
"I could have made more money feeding ducks in the memory campus," grumbled Lee HJ, a 33-year-old engineer in the system LSI division of a major Korean conglomerate.
The joke has spread widely across Korean workplace forums after employees assigned to memory-chip businesses were expected to receive bonuses worth hundreds of millions of won, while Ph.D.-level engineers in loss-making system LSI and foundry units were set to receive far less.
"Someone feeding ducks can receive 400 million to 500 million won just because they belong to the semiconductor division," Lee said, capturing growing frustration over widening internal pay gaps.
The tensions are most visible at Samsung Electronics, where the company's representative union approved a tentative 2026 wage agreement on Wednesday, averting an immediate strike at the world's largest memory-chip maker and easing concerns over disruptions to AI supply chains and South Korea's stock market.
Electronic voting held from May 22 through Wednesday morning drew participation from 95.5 percent of 65,593 eligible voters, with 73.7 percent approving the deal.
The agreement — reached just one day before a planned strike deadline — includes an average 6.2 percent wage increase and a newly created special performance bonus tied to operating profit. Under the deal, Samsung will institutionalize a bonus pool linked to 10.5 percent of annual operating profit, mirroring a structure already adopted by SK hynix.
By contrast, employees in Samsung's foundry and system LSI divisions, which remain under earnings pressure, are expected to receive around 210 million won, while some workers in the smartphone and consumer-electronics businesses may receive only around 6 million won.
The nearly 100-fold disparity has fueled unusually sharp tensions inside Samsung over widening compensation inequality.
The rush to carve up corporate earnings has spilled well beyond the lucrative chip segment.
Park Byung-jin, a professor at Hanyang University's School of Business, said Samsung's bonus deal would have a "domino effect" across South Korea's labor market and corporate compensation systems.
"A bonus structure with no clear ceiling at the country's most influential company could trigger broader 'bonus inflation' across Korea," he said. "Once it becomes a reference point, unions at other major firms will naturally push for similar payouts."
HD Hyundai Heavy Industries' union has included 30 percent operating-profit sharing in its bargaining proposal, while Kakao's union is pushing for bonuses worth 13 percent to 14 percent of operating profit. LG Uplus has also faced demands for bonuses tied to roughly 30 percent of operating profit.
SM, a 33-year-old senior manager at a major Korean automaker, said the dispute ultimately comes down to how a limited pool of money is divided.
"There is no such thing as a win-win structure," he said. "The more one side takes, the less remains for someone else. Eventually, somebody has to give something up."
The conflict is no longer a simple clash between labor and management. It is spreading across multiple fault lines: business divisions, job categories, regular and subcontracted workers, primary contractors and suppliers, and even shareholders and employees.
Inside platform and ICT firms, tensions are increasingly emerging between developers, marketers, sales teams and support staff over who truly creates value in AI-driven businesses and how those profits should be distributed.
Similar disputes are surfacing across other industries. Samsung Biologics faced its first-ever strike earlier this month after talks collapsed over demands including profit-linked bonuses and higher compensation.
The rise in profit-linked bonuses is also widening disparities between large corporations and smaller firms, intensifying feelings of relative deprivation among workers outside the AI boom.
According to Labor Ministry data released in 2025, bonuses and incentives accounted for 24.7 percent of wages at companies with more than 1,000 employees in 2024, compared with about 8 percent at smaller firms. Monthly bonuses at large corporations averaged roughly 1.33 million won, nearly four times the 340,000 won average at smaller companies.
According to National Tax Service data on 2024 earned-income filings, the average annual salary for Korean workers stood at roughly 45 million won, or about 3.75 million won per month. However, the median annual salary — the midpoint at which half of workers earn more and half earn less — was only 34.17 million won, or about 2.85 million won per month.
The gap of more than 10 million won between the average and median underscores how high-income earners continue to skew overall wage statistics upward, while the majority of workers experience significantly lower real incomes. On a pretax basis, nearly half of Korean salary earners make less than 3 million won a month.
Against that backdrop, compensation demands such as those raised by Samsung's union risk deepening the sense of inequality felt by ordinary workers. Some industry estimates suggest that if Samsung were to allocate 15 percent of operating profit to performance bonuses, as demanded by labor representatives, employees in the DS memory division could receive average bonuses totaling 2.61 billion won per person between 2026 and 2028.
"Some people are barely getting through the month, while others are fighting over bonuses worth hundreds of millions of won," said David Song, a 35-year-old employee at an IT company in Seoul. "Smaller companies don't have the unions or bargaining power. It feels like we are living in a different world."
The disputes are also spreading through Korea's broader contractor ecosystem.
Large manufacturers depend heavily on subcontractors and outsourced workers, from logistics providers to cafeteria, cleaning and security staff operating inside the same industrial sites.
"Is it reasonable to pay cleaners 80 percent of what regular employees receive?" said Kim JW, a 28-year-old employee at a major manufacturing conglomerate. "Situations like this only deepen resentment toward subcontracted workers."
The issue has become more sensitive following revisions to South Korea's labor union law — often referred to as the "Yellow Envelope Act" — which expanded the responsibilities of primary contractors and increased pressure on large manufacturers to address widening bonus gaps across contractor networks.
A logistics subcontractor union tied to SK hynix has demanded collective bargaining over bonus disparities, while a cafeteria-service union linked to Hanwha Ocean has also called for expanded bonus payments. The conflict is increasingly moving beyond directly employed workers into the wider subcontractor ecosystem.
The debate is also colliding with shareholder concerns. Some investors argue that shareholders absorb losses during downturns while employees increasingly demand larger shares of profits during boom years. Critics warn that escalating bonus structures could weaken dividends and reduce long-term investment capacity.
"That means companies may end up rewarding thousands of employees just to retain a handful of key engineers," he said.
To address the problem, Park said Korean companies would eventually need to scale back broad group-based bonuses such as OPI and shift more resources toward targeted retention bonuses designed to prevent critical talent from leaving.
"That would help reduce overall cost burdens while protecting irreplaceable engineers and top performers," he said.
Park also argued that companies should first account for shareholder returns and capital costs before distributing incentives based on economic value added, or EVA — a measure of profit after deducting capital costs — in order to ease tensions between shareholders and employees.
He further suggested replacing part of large cash payouts with restricted stock units, or RSUs, arguing that bonuses above a certain threshold should be paid in shares with multiyear lockup periods rather than immediate cash. Such a structure, he said, would align employees more closely with long-term shareholders.
Park also warned that applying identical profit-based compensation standards to both highly profitable memory-chip divisions and future-growth businesses such as foundry and system LSI could deepen internal divisions. Instead, he said, future-oriented businesses should be evaluated using longer-term indicators such as technology milestones, customer orders and market-share growth rather than short-term profits alone.
"The core shift," Park said, "is moving away from broad group bonuses toward a more targeted compensation system focused on shareholders and irreplaceable talent."
Samsung's approved agreement partly reflects that transition. Under the deal, portions of special bonuses will be paid in company shares subject to lockup periods, marking an early shift away from immediate cash payouts toward longer-term stock-linked compensation.
South Korea's AI-era bonus wars are no longer simply disputes over wages. They are becoming a broader test of whether Korean companies can preserve organizational and social cohesion while fairly distributing increasingly concentrated profits in the AI economy.
