Samsung's Largest Union to the ₩400 Trillion Gwangju Chip Factory: "Don't Leave Workers Out of This

Just three days after Samsung Electronics officially announced plans to pour ₩400 trillion into a massive semiconductor complex in Gwangju, the company’s largest labor union broke its silence. On July 1st, the Samsung Electronics Super-Enterprise Union — the biggest of Samsung’s labor organizations — issued a formal statement. The message was blunt: “This is great news, but the people who’ll actually be working there deserve a seat at the table.” That one sentiment is now sending ripples through Samsung’s internal landscape in ways that are anything but simple.

Why Samsung’s Biggest Union Spoke Up — and Why Now

On June 29th, at a national investment showcase held at the presidential guest house, Samsung Chairman Lee Jae-yong personally announced plans to invest ₩400 trillion in a new semiconductor campus, naming Gwangju as the top candidate site. It was the moment South Korea’s southwestern semiconductor cluster — a flagship government initiative — officially took shape.

For the union, though, this announcement landed with mixed feelings. It signaled that Samsung’s semiconductor (DS) division employees — currently concentrated in Giheung, Hwaseong, Suwon, and Cheonan across the greater Seoul and Chungcheong regions — could one day face transfers to Gwangju. For workers whose lives, families, and routines are anchored in central Gyeonggi and Chungcheong provinces, the prospect of a major Honam-region factory wasn’t just big news. It was a deeply personal one.

The Union’s Statement Boiled Down to Three Key Points

The Samsung Electronics chapter of the Super-Enterprise Union responded to the southwestern semiconductor mega-project with a clear demand: any major decisions must involve a tripartite dialogue between labor, management, and government. The July 1st statement centered on three core themes.

No rushing: The union called the mega-project “a task that will determine the future of South Korea’s semiconductor industry,” urging that “thorough preparation must take precedence over urgency — this requires a long-term vision.” In effect, the union is putting the brakes on the government’s push for speed.
People first: “At the foundation of all this are the people,” the statement read, stressing that workers need proper industrial safety standards, livable housing, and adequate infrastructure at any new site — along with compensation that matches the demands being placed on them.
A real seat at the table: The union’s central demand is straightforward — stop making decisions behind closed doors between management and government alone. Workers must be included in the process from the start.

The Union Had Been Watching This Closely From the Beginning

This statement didn’t come out of nowhere. Back on June 10th, when rumors of Samsung and SK Hynix both pursuing southwestern semiconductor plants began circulating, the Super-Enterprise Union had already sent a formal letter to Samsung management demanding clarification. The company’s response at the time? “We don’t know anything about that.” The union went through official channels and got stonewalled. Then Chairman Lee made his Gwangju announcement publicly — and the union realized it could no longer afford to wait on the sidelines.

A Bonus Dispute That’s Far From Over

The Gwangju controversy is playing out against the backdrop of a labor-management conflict that hasn’t fully healed. In May, Samsung and its union reached a dramatic agreement on the performance bonus structure, brokered by Employment Minister Kim Young-hoon — a breakthrough that came five months into a bitter wage dispute. But the deal was far from a clean resolution. Employees in the semiconductor Memory division stand to receive bonuses of up to ₩600 million, while workers in the non-semiconductor DX division (smartphones and home appliances) received essentially nothing beyond what amounts to a consolation prize: company stock worth roughly ₩6 million. The compensation gap between DS and DX employees remains a live and unresolved tension.

DS Split Bargaining, Union Rivalries — the Labor Landscape Is Shifting

The Gwangju issue is also scrambling the dynamics within Samsung’s union ecosystem. Super-Enterprise Union chairman Choi Seung-ho, after being re-confirmed in his role, announced plans to pursue separate collective bargaining for the DS division — leveraging a labor board mechanism that allows bargaining units to split — with implementation set to begin as early as July. If that separation goes through, semiconductor workers and smartphone/appliance workers will negotiate at entirely different tables. Since DS division employees would make up the core of any Gwangju workforce, how that bargaining plays out has direct implications for what working conditions in the new facility will look like.

Meanwhile, the National Samsung Electronics Labor Union (known as Jeon Sam No), which primarily represents DX division employees, effectively rejected the May bonus agreement — its members voted only 21.1% in favor. The union is now pushing independently for a formal meeting with the DX division’s CEO, signaling that it has no intention of falling in line.

The Real Reason the Union Is Worried About a ₩400 Trillion Project

It’s important to understand that this isn’t opposition for opposition’s sake. Building a semiconductor cluster of this scale — unprecedented anywhere in the world — in Gwangju raises a mountain of practical challenges that can’t be wished away. If tens of thousands of chip engineers currently rooted in Gyeonggi and Chungcheong are expected to relocate to Gwangju, they’ll need housing, good schools for their children, and reliable transportation infrastructure before any of that can realistically happen. That’s precisely why the union’s emphasis on “thorough preparation over speed” isn’t just posturing — it reflects the lived reality of the people being asked to make that move.

This is about far more than relocating a factory. For the ₩400 trillion project to succeed, three things need to move in sync: government investment in infrastructure, Samsung’s commitment to fair compensation and working conditions, and genuine early dialogue with the workers who will build and run these facilities. The union’s demand for a tripartite negotiating table is a clear signal that one of those three legs is still missing — and that someone needs to say so out loud.
