Korea bargaining expanded after law change
One month after South Korea revised its so-called 'yellow envelope' law, bargaining coverage has widened though not to the extreme some feared. The Korea Times reports expansion in collective bargaining since the law took effect, offering a cautionary example of how legal changes can alter employer–worker dynamics. (koreatimes.co.kr)
A month after South Korea’s revised “yellow envelope law” took effect on March 10, principal contractors are bargaining with more subcontractor unions, but labor boards have not forced talks with “hundreds or thousands” of unions at once. (koreatimes.co.kr) The law amended Articles 2 and 3 of the Trade Union and Labor Relations Adjustment Act after the National Assembly passed it on August 24, 2025, and the government promulgated it on September 9, 2025. It broadened the definition of “employer” to cover firms that substantially control working conditions even without directly hiring the workers. (industrialrelationsnews.ioe-emp.org, koreaherald.com) That change lets subcontracted workers seek direct bargaining with the main contractor when the contractor effectively sets hours, staffing levels or work processes. The Ministry of Employment and Labor also said disputes can now cover management actions like layoffs, transfers and restructuring steps that change working conditions. (koreaherald.com, koreajoongangdaily.joins.com) In the first month, labor authorities recognized employer status more broadly but kept bargaining units narrower than some business groups predicted. The Korea Times reported that Incheon International Airport Corporation was told to bargain in three subcontractor units, while POSCO’s subcontractor unions were divided into three units rather than dozens. (koreatimes.co.kr) The Ministry of Employment and Labor said business warnings were “excessive” after those early rulings. At POSCO, the ministry said authorities recognized three bargaining units for more than 50 subcontractors, and at Incheon airport they narrowed seven unions into three units. (koreatimes.co.kr) Pressure on employers has still increased. The Dong-A Ilbo reported that since March 10, 987 subcontractor unions had requested negotiations with 368 primary contractors, but only 31 companies had formally posted notices to begin talks. (donga.com) The enforcement rules help explain both trends. Government guidelines issued before March 10 said employer status should be judged by “structural control,” and they made principal-company unions and subcontractor unions separate bargaining units by default. (kimchang.com, littler.com) Those same rules also allow labor boards to split subcontractor bargaining units by union affiliation when interests differ or inter-union conflict is likely. That is why Incheon airport’s unions were separated into Federation of Korean Trade Unions, Korean Confederation of Trade Unions and other groups, instead of being treated as one bloc. (kimchang.com, koreatimes.co.kr) Business groups say the line between core management and bargainable issues is still blurry. Korea JoongAng Daily reported that companies worry decisions on automation, investment and factory changes could be challenged if unions argue they will alter jobs or staffing. (koreajoongangdaily.joins.com) Labor groups and the government have argued the law mainly gives subcontracted workers a path to negotiate with the entity that actually controls their jobs, especially in workplaces where contractors and subcontractors work side by side. One month in, the early rulings show wider bargaining coverage, but through a managed set of bargaining units rather than the unlimited sprawl that employers had forecast.
