« Yellow Envelope Act »: amendment of articles 2 and 3 of the Trade Union Act

Law No. 21045 of 9 September 2025 amends articles 2 and 3 of the Trade Union and Labor Relations Adjustment Act. Whoever substantially and specifically controls a worker’s working conditions — typically a principal contractor towards subcontracted workers — becomes an employer within that scope; industrial disputes may cover business decisions that affect working conditions; courts must split damages for strikes worker by worker. Passed twice and vetoed twice (2023, 2024), the text was adopted on 24 August 2025 and has been in force since 10 March 2026.

Status

In force

since March 10, 2026[1][2][14]

The new limits on damages apply to losses arising from 10 March 2026; an employer’s waiver of liability also covers earlier losses.

Stated objective

Make the constitutional labour rights effective where several companies share control over work: the firm that really sets working conditions should bargain with the workers concerned, instead of hiding behind the absence of a contract while the contracting employer lacks the power to improve those conditions. Bring restructuring and breaches of collective agreements within the scope of disputes, and end damages awards that threaten unions’ survival and strikers’ households.[6][2]

according to the reasons stated in the Environment and Labor Committee’s alternative bill (July 2025)

Main measures

  • Employer (article 2, item 2): a person who is not party to the employment contract but can substantially and specifically control and determine a worker’s working conditions is an employer within that scope — in practice, a principal contractor can be required to bargain with its subcontractors’ unions.[2][10]
  • Union recognition (article 2, item 4(d) repealed): a union is no longer denied its status because some of its members are not workers.[2][10]
  • Industrial disputes (article 2, item 5): besides the determination of working conditions, disputes may concern business decisions that affect working conditions (according to the ministry, redundancies or transfers resulting from restructuring) and an employer’s clear breach of the collective agreement on certain conditions (wages, working time, safety and health…).[2][10][14]
  • Damages (article 3): the ban on claiming damages for bargaining and industrial action carried out in accordance with the Act is extended to other union activities; no claim either for harm caused in unavoidable defence against an employer’s unlawful act; when a court holds workers liable, it must set each worker’s share according to their role, involvement, wage level and the cause of the damage, and may reduce or cancel it on request in view of their means and family duties.[2]
  • Other guarantees (articles 3 and 3-2): personal guarantors are no longer liable for union-related damages; employers may not use damages claims to threaten a union’s existence or obstruct union activity; employers may waive the liability of unions and workers, including for losses prior to 10 March 2026.[2]
  • Enforcement decree (article 14-11): subcontractors’ unions go through the existing single bargaining channel with the principal; labour commissions may separate bargaining units for subcontracted workers, giving priority to common interests, adequate representation and the risk of conflict between unions.[12][13]

Timeline

  1. Under debate

    Environment and Labor Committee adopts an alternative bill (21st National Assembly)[3]

  2. Adopted

    Passed by the National Assembly (173 for, 0 against, 1 abstention)[3]

    Bill No. 2123038; the President sends it back for reconsideration on 1 December 2023.

  3. First veto: the government asks the Assembly to vote again[8][3]

    The Cabinet resolves to request reconsideration under article 53(2) of the Constitution. The Ministry of Employment and Labor cites a vague definition of the employer, strikes over matters handled by courts and labour commissions, and an exception to joint liability for damages granted to unions alone.

  4. Abandoned

    Rejected at the re-vote after the presidential veto[3][7]

    The bill is rejected at the new vote and therefore lapses.

  5. Public hearing in the Environment and Labor Committee[7]

    The Korea Enterprises Federation on one side, the KCTU and the FKTU on the other, set out opposite positions, summarised in the committee’s 2025 review report.

  6. Under debate

    New alternative bill adopted in committee (22nd National Assembly)[4]

  7. Adopted

    Passed again by the National Assembly (177 for, 2 against)[4]

    Bill No. 2202444; the President’s request for reconsideration reaches the Assembly on 19 August 2024.

  8. Cabinet examines a second request for reconsideration[9]

    The opening remarks of the meeting argue that the new text goes further than the one rejected in 2023, by also protecting « persons who are not workers » and widening the limits on damages.

  9. Abandoned

    Rejected again at the re-vote after the second veto[4][7]

  10. Under debate

    Environment and Labor Committee adopts a third alternative bill[6][5]

    Seven member bills merged; the Legislation and Judiciary Committee amends the wording on 1 August 2025.

  11. Adopted

    Passed by the National Assembly (183 for, 3 against), then promulgated on 9 September 2025[5][11][2]

    186 members present out of 298. The Act enters into force six months after promulgation.

  12. Promulgation as Law No. 21045[11][2]

    Transmitted to the government after the vote of 24 August, the Act is approved by the Cabinet on 2 September and promulgated on 9 September 2025, with entry into force set for 10 March 2026.

  13. Consultation on the enforcement decree, then a revised draft[12]

    A first draft is open for comments from 25 November 2025 to 5 January 2026; a revised draft, from 21 January to 6 February 2026, separates the general rules on bargaining units from those applying to subcontracted workers.

  14. Enforcement decree adopted and interpretive guidelines finalised[13]

    The Cabinet adopts the decree; the ministry finalises its interpretive guidelines after public comment from 26 December 2025 to 15 January 2026 and sets up an advisory committee to rule on employer status.

  15. In force

    Entry into force of the amended articles 2 and 3[1][2][14]

    The new limits on damages apply to losses arising from 10 March 2026; an employer’s waiver of liability also covers earlier losses.

  16. Government assessment after 100 days[15]

    By 19 June 2026, 1,161 subcontractors’ unions had asked 439 principal workplaces to bargain; labour commissions had recognised 103 principals as employers and 10 workplaces had opened formal talks.

  17. Guideline on profit-sharing bonuses and business decisions[16]

    The ministry states that demands for a bonus set as a share of revenue or profit are not a mandatory bargaining subject nor a lawful ground for industrial action, though they may be negotiated voluntarily.

  18. First principal–subcontractor collective agreement under the amended law[17]

    Hyundai Steel and the unions of four of its subsidiaries sign an agreement on occupational safety and health, the subject on which a labour commission had recognised Hyundai Steel as an employer.

The debate

Citoyen takes no position: arguments are reported as their authors put them.

According to its supporters

  • The KCTU and the FKTU argue that indirect and special forms of employment are spreading while workers cannot exercise their labour rights towards the firm that actually sets their conditions, and that employers’ damages claims are used as a tool to restrict those rights.[7]
  • The committee’s alternative bill states that courts hold every participant in a strike jointly liable for the whole loss without assessing each one’s part, threatening unions’ existence and causing financial hardship and family breakdown among strikers.[6]
  • Minister Kim Young-hoon calls it a law to « promote dialogue » and narrow labour-market gaps, stressing that it means neither unlimited bargaining or strikes nor unconditional immunity for illegal strikes.[10]
  • After 100 days, the ministry reports no « bargaining tsunami »: 2.6 demands per principal workplace on average, new demands falling from 363 workplaces in March to 23 more in May, and bargaining units split in 12 of 29 cases, into 2.2 units on average.[15]

According to its opponents

  • The Korea Enterprises Federation (KEF) argues that widening the notions of worker, employer and industrial dispute disrupts the bargaining order, breaches the principle of legal clarity and undermines legal certainty, and that limiting damages even for illegal strikes would encourage them and excessively restrict employers’ property rights, to the detriment of competitiveness.[7]
  • The KEF adds that countries such as the United States, the United Kingdom, Japan and France, which accept a broad scope for strikes, balance it with counterweights for employers: a ban on occupying workplaces (Germany, United States, France) or the right to hire replacement workers during a strike (Germany, United States, Japan, United Kingdom, France).[7]
  • In vetoing the 2023 bill, the government of the time (Ministry of Employment and Labor) argued that the « substantial and specific control » test leaves principals unable to foresee with whom and on what they must bargain, although refusing to bargain is a criminal offence, and that strikes over rights already settled by courts and labour commissions would multiply.[8]
