The ruling Democratic Party of Korea (DPK) unilaterally pushed the so-called "yellow envelope bill" through the National Assembly Monday, igniting one of the fiercest debates around labor in years. The bill broadens the definition of "employer" and restricts companies on claiming substantial compensation from striking unions — a measure that labor groups have sought for over a decade and which business leaders and conservatives have fought just as hard to block.
The passage of the yellow envelope bill — named after a 2014 grassroots campaign in which the public sent donations in yellow envelopes to laid-off SsangYong Motor workers facing damage compensation lawsuits — would mark a major victory for President Lee Jae Myung, fulfilling a key campaign pledge and reinforcing his pro-labor stance. By pushing ahead with the contentious legislation, Lee shifts policy priorities toward union and worker protections, even as the move draws sharp criticism from the business community. The decision contrasts with his recent efforts to court corporate leaders and promote deregulation to boost growth.
The bill advanced through the judiciary committee but will not proceed to a full vote immediately following the end of the filibuster. Lawmakers have postponed the final vote until later in August.
Previous attempts to enact the amendment had faltered, but the president revived the proposal this year, framing it as part of his commitment to restoring what he described as fairness in the workplace. During a visit last month to a factory run by confectioner SPC, where several workers had died, Lee condemned "low wages and long hours," signaling his administration’s intent to overhaul labor practices affecting subcontracted workers.
At its core, the yellow envelope bill amends three key aspects of Korean labor legislation. It expands the definition of "employer" to include parent companies or entities with "substantial control" over working conditions, allowing food delivery drivers and auto parts assemblers to bargain directly with conglomerates rather than just the subcontractors that employ them. The law also broadens the scope of legally protected strikes to cover not only wages and hours but also major corporate decisions like mass layoffs and plant closures.
It also limits how far companies can go when suing unions for compensation for damage caused during labor actions — a direct response to costly claims that followed the 2009 SsangYong Motor strike, which critics said had intimidated workers into silence.

The DPK characterized the overhaul as a move to align the country with international labor standards. Rep. Huh Young, the party’s chief policymaker, said the bill "draws on International Labour Organization recommendations, EU trade demands and recent Supreme Court rulings," calling it "a crucial step towards easing conflict and opening dialogue in the workplace." Party leaders have rebranded the legislation as the Industrial Peace Promotion Act, arguing that clearer liability rules and limits on what they describe as "excessive lawsuits" will foster more stable labor relations.
But the backlash was both swift and heated.
Business lobby groups warned that holding parent companies accountable for subcontractor disputes could trigger a chain reaction of strikes and disrupt production.
Sohn Kyung-shik, chairman of the Korea Enterprises Federation, said, "If hundreds or even thousands of subcontractor unions demand bargaining, companies won’t be able to cope. Many will simply relocate operations overseas."
The conservative People Power Party labeled the reform an "industrial paralysis law" and a "license for illegal strikes." PPP spokesman Park Sung-hoon said the bill has "planted a time bomb in the heart of Korea’s economy." PPP lawmakers staged a filibuster in protest, but the ruling coalition, holding a sufficient majority, ended it after 24 hours, delaying the process by just one day.
Unusually for a political clash of this scale, the government also weighed in.
Labor Minister Kim Young-hoon described the bill as "a way to spark dialogue and cut down on disputes," releasing a detailed explanation to ease business concerns. He emphasized that only firms with "direct and substantial control" over employees’ working conditions would be considered employers, aiming to reassure companies that they would not be overwhelmed with bargaining demands.
For the president, the yellow envelope bill represents more than labor reform — it is a defining statement of his presidency. He has positioned himself as a leader willing to challenge entrenched corporate practices and align Korea with global labor standards. His administration argues that the law will strengthen workers’ rights and create what it described as "predictable, rules-based relations" that could stabilize the economy over time.
If passed, the law is set to take effect in six months — but the political and economic divisions it has laid bare are unlikely to fade anytime soon.
