Official text on the National Law Information Center

  1. Question

    When discriminatory treatment of a dispatched worker who has passed the retirement age is assessed, who should be taken as the comparator employee, and what is the reference wage for calculating the amount of damages?

  2. Holding

    The comparator employee is, in principle, a regular employee at the user enterprise's workplace who has passed the retirement age and performs the same kind or similar work; if there is none, an employee on a fixed-term contract such as a rehired retiree (choktak); and if there is none of those either, an employee who has not passed the retirement age, provided that the circumstance of having passed the retirement age must be taken into account in determining whether a reasonable ground exists. The reference wage is the appropriate wage that the user enterprise would have paid had it hired an employee who had passed the retirement age, and the Supreme Court held that the right to claim damages arising from discrimination continued by the custodian after the commencement of the rehabilitation proceedings constitutes a common benefit claim.

    Not addressed Not in the decision

  8. Open question and revisit condition

    Where there has been no precedent whatsoever of temporarily employing retired employees and no practice at similar workplaces can be confirmed, on what materials must the appropriate wage of an employee who has passed the retirement age be calculated?

    This reading will be re-examined if Article 21 of the Act on the Protection, etc. of Temporary Agency Workers or Article 179, paragraph (1), subparagraph 5 of the Debtor Rehabilitation and Bankruptcy Act is amended, or if a subsequent decision is handed down concerning the calculation of the reference wage for a dispatched worker who has passed the retirement age.

Cross-family AI independent reading & axis check

6 of 8 axes matched GPT-6 Astra (OpenAI, codex CLI) · 2026-10-16

Compared with an independent reading by a different AI line (GPT-6 Astra), which read only the original text without seeing the primary reading, 6 of the 8 axes agreed, and the readings diverged on the 4th axis (Form of the test) and the 5th axis (Factors).

Axis 4 (Form of the test): Primary “Elements stated” vs Independent “Circumstances weighed”

Since the original text sets out a method for selecting the comparator and a standard for the appropriate wage while also requiring consideration of the circumstance of having passed the retirement age, the primary reading may emphasize the structure of the elements, while the independent reading may emphasize the totality of the circumstances.

파견근로자의 정년이 경과하였다는 사정을 불리한 처우에 합리적 이유가 있는지 판단하는 데에 고려하여야 하는지 여부(적극)

Axis 5 (Factors): Primary “Whether the dispatched worker's right to claim damages arising from such tort by the custodian falls under the common benefit claim of Article 179, paragraph (1), subparagraph 5 of the Debtor Rehabilitation and Bankruptcy Act (affirmative) / Whether the foregoing legal principle applies insofar as, in practical terms, the dispatched worker engages in work for the user enterprise in the capacity of a dispatched worker (affirmative) / Method for selecting the comparator employee / Whether the circumstance that the dispatched worker has passed the retirement age must be taken into account in determining whether there is a reasonable ground for the disadvantageous treatment (affirmative)” vs Independent “knew or could have known that the same kind of work or similar work was being performed / by participating in or exercising influence over the determination of the dispatched worker's wages, etc. / the circumstance that the dispatched worker has passed the retirement age / the appropriate wage that the user enterprise would have paid had it hired an employee who had passed the retirement age”

Having passed the retirement age is common to both, but the primary reading focuses on the common benefit claim character, the actual dispatched status, and the selection of the comparator, while the independent reading focuses on the awareness of similarity of work, participation in wage determination, and the appropriate wage.

Lower-court contrast & scope of application

Lower-court reading vs. Supreme Court holding

Lower-court context: The court below rejected the defendant's defense, raised prior to the merits, that the plaintiffs' right to claim damages had lapsed as a rehabilitation claim, and held it to be a common benefit claim; it found the dispatched worker relationship established and upheld Plaintiff 1's claim for confirmation of employee status and the plaintiffs' claim for damages for wage differentials. It held that the circumstance that Plaintiff 2 provided labor after having passed the retirement age does not warrant a different view, and it also rejected the assertions of comparative negligence, completion of extinctive prescription, and the principle of good faith or estoppel.

Supreme Court standard: While the final appeal was pending, the Supreme Court held ex officio that Plaintiff 1 reached the retirement age on December 31, 2022, so that the interest in confirmation was lost; it reversed that portion, vacated the judgment of the first instance court, and dismissed the action on procedural grounds. As to the remainder, it found no error in the judgment of the court below in light of the common benefit claim character, the finding of worker dispatch, the legal principle concerning the comparator and the reference wage for a dispatched worker who has passed the retirement age, and the commencing date of extinctive prescription, and dismissed the final appeal.

Distinguishing conditions

  • Where what is at issue is a right to claim damages arising from discriminatory treatment that had already occurred before the commencement of the rehabilitation proceedings
  • Where there is, at the user enterprise's workplace, a regular employee or choktak employee who has passed the retirement age and performs the same kind or similar work, so that there is no need to take an employee who has not passed the retirement age as the comparator
  • Where the retirement age has not yet been reached, so that an existing anxiety and risk remain for which confirmation of employee status may be sought

Record verification notes

Before asserting the same conclusion, first confirm whether the user enterprise participated in or exercised influence over the determination of the dispatched worker's wages, whether the discrimination was continued by the custodian after the commencement of the rehabilitation proceedings, and whether there are materials supporting the appropriate wage that would have been paid had the user enterprise hired an employee who had passed the retirement age.
