This case involved an employee who resigned from a company to change job types, joined a subsidiary company, and later returned to the original company. The Korean Supreme Court (대법원) ruled that since the initial resignation was valid, the employee's years of continuous service (근속연수) for severance pay (퇴직금) purposes should be calculated starting from the re-employment date. However, the court also held that a collective bargaining agreement (단체협약) alone cannot retroactively validate a severance pay regulation that was amended to the employee's disadvantage.

Key takeaways
  • CaseAn employee who resigned to change job types, worked at a subsidiary, and later returned to the original company disputed how his severance pay (퇴직금) should be calculated.
  • OutcomeThe court ruled that since the voluntary resignation was valid, service years for severance pay purposes start from the re-employment date, but an unfavorable change to severance pay rules cannot be retroactively validated merely by a collective bargaining agreement.
  • LessonWhen changing severance pay regulations in a way that disadvantages employees, employers must obtain individual employee consent or follow additional procedures beyond simply concluding a collective bargaining agreement.
Issues
  • Whether resignation followed by re-employment (for the purpose of changing job type) was legally valid
  • The legal effect of amending severance pay payment regulations in a way disadvantageous to employees
  • Whether a collective bargaining agreement can retroactively ratify an employee-disadvantageous regulation
Key reasoning

A resignation made by an employee's own voluntary decision is not invalidated merely because it was later followed by re-employment, nor does it constitute a sham transaction (통정허위표시) or violate the Labor Standards Act (근로기준법). Therefore, the resignation and subsequent re-entry were valid, meaning the employee's continuous service period restarted from the date of re-employment. However, when severance pay regulations are amended in a way that disadvantages employees, such changes cannot be deemed retroactively ratified simply because a collective bargaining agreement was later concluded. Retroactive validation of unfavorable regulatory changes requires more than the mere existence of a collective agreement; it demands clear and specific consent or ratification addressing the disadvantageous change itself.

Summary of Decision (English, AI translation)

[1] A case holding that where a technical (production) employee of a parent company, upon being informed that a change of job category to clerical (office) work would result in transfer to a newly established subsidiary, resigned from the parent company and went through the procedures for employment with the subsidiary, such resignation does not become void as a false declaration made by conspiracy (통정허위표시) or as a violation of the Labor Standards Act (근로기준법).

[2] A case holding that an amendment to retirement allowance payment regulations (퇴직금지급규정), which was disadvantageous to the employees, cannot be deemed to have become effective by reason of subsequent retroactive ratification.

[Plaintiff, Appellant]

[Defendant, Appellee] Korea Tourism Corporation (Attorneys Kim Dong-hwan and 2 others as litigation representatives)
[Judgment Below] Seoul High Court Decision 91Na47552 rendered on April 20, 1992

[Order]

The judgment below is reversed, and the case is remanded to the Seoul High Court.

[Reasoning]

On the grounds of appeal by the Plaintiff's litigation representatives

1. According to the reasoning of the judgment below, the court below found, based on the evidence adopted, the following facts: that Defendant Corporation is a juristic person established under the Korea Tourism Development Corporation Act (한국관광개발공사법) for the purpose of carrying out projects relating to the promotion of the tourism industry, the development of tourism resources, research and development of the tourism industry, and the training and cultivation of tourism personnel; that when the development project of the Gyeongju Bomun Tourist Complex was commenced under the supervision of the Ministry of Construction around 1974, Defendant Corporation, on August 6 of that year, dispatched about ten employees, including the Plaintiff, to the Gyeongju Development Office of the Ministry of Construction to work at the Gyeongju site, and that on October 25 of the same year, Defendant Corporation established a Gyeongju Liaison Office under its Development Department and had the Plaintiff and other employees dispatched to the Gyeongju site continue to work as employees belonging to the said Gyeongju Liaison Office; that around July 1975, the development project of the aforementioned Gyeongju Bomun Tourist Complex was substantially completed, and on July 25, in order to take over and manage the Gyeongju Bomun Complex constructed under government supervision as described above and to develop and maintain it as a comprehensive tourist complex of international standard, the non-party Gyeongju Tourism Development Corporation Co., Ltd. (hereinafter "the non-party company") was established as a separate juristic person; that the non-party company, with the assistance of Defendant Corporation, thereupon proceeded to recruit employees, and that the Plaintiff, who was at the time working as a technical staff member at Defendant Corporation, expressed his intention that he would move to the non-party company if he could change his job category to clerical staff and work as a clerical employee, and that the non-party company accepted this, whereupon the Plaintiff submitted his resignation to Defendant Corporation on July 31, 1975, received his retirement allowance, retired from Defendant Corporation, and from the following day worked as a clerical employee at the non-party company; and that thereafter, upon learning around March 1977 that Defendant Corporation was recruiting experienced employees, the Plaintiff submitted his resignation to the non-party company on March 31, 1977 and retired therefrom, and rejoined Defendant Corporation on April 1 of the same year, continuing to work as a clerical employee until he retired from Defendant Corporation on October 17, 1989. Based on these findings, the court below determined that the Plaintiff's retirement from Defendant Corporation on July 31, 1975 was, rather than constituting any disadvantage or unreasonable treatment of the Plaintiff, in fact favorable treatment of the Plaintiff in that it allowed him to work as a clerical employee, and that, insofar as there is no ground to find any intent to evade the Labor Standards Act (근로기준법) or any culpability in violation of the principle of good faith, social justice, or equity, the Plaintiff's declaration of intent to retire should be regarded as a juristic act done of his own free will; therefore, the said retirement and re-employment cannot be deemed void as a false declaration made in collusion or as a violation of the Labor Standards Act, and accordingly the period of continuous service for the purpose of calculating the retirement allowance runs from April 1, 1977, the date of re-employment. The above fact-finding and determination by the court below are acceptable, and it cannot be said that there is any illegality in violation of the rules of evidence or any error in the legal interpretation regarding the calculation of the period of continuous service, as argued in the grounds of appeal. This ground of appeal is without merit.

2. In the reasoning of its judgment, the court below stated that the retirement allowance payment regulations of Defendant Corporation as amended effective January 1, 1981 were changed disadvantageously, as indicated in the judgment, for employees who had been subject to the previous regulations, and that since there was no consent to such change obtained through the collective decision-making method of these employees, the said amended retirement allowance payment regulations should be deemed void; however, the court below further determined that although the employees of Defendant Corporation were aware that the amended retirement allowance payment regulations were disadvantageous to them and thus void, because the regulations had been implemented for a long period without objection, the labor union organized by employees belonging to Defendant Corporation, including the Plaintiff, when concluding a collective agreement with Defendant Corporation on December 31, 1984, established retirement allowance regulations with the same content as the disadvantageously amended retirement allowance payment regulations; that this constitutes a case in which the void retirement allowance payment regulations were accepted as valid and their retroactive application was ratified at the same time; and that, accordingly, the amended retirement allowance payment regulations should also apply to the Plaintiff.

However, there is no material to find that the Plaintiff joined the said labor union (see Defendant's Exhibit No. 5-1 and Exhibit No. 6-1), and moreover, no evidence can be found to establish that the employees of Defendant Corporation, at the time of concluding the said collective agreement, were aware that the amended retirement allowance payment regulations were void due to the aforementioned circumstances. If this is so, it cannot be said that the amendment of the retirement allowance payment regulations became effective through subsequent retroactive ratification, and therefore the determination of the court below, which is inconsistent with this, constitutes an illegality in that it misapprehended the facts in violation of the rules of evidence and failed to exhaust the necessary deliberation. This ground of appeal is meritorious.

For the foregoing reasons, the judgment below is reversed and the case is remanded to the court below, this Judgment being rendered as set forth in the Order by the unanimous opinion of the participating Justices.

【이 유】 원고 소송대리인들의 상고이유에 대하여

1. 원심판결 이유에 의하면, 원심은 채택증거에 의하여, 피고 공사는 관광사업의 진흥, 관광자원의 개발, 관광사업의 연구개발 및 관광요원의 양성, 훈련에 관한 사업의 수행을 목적으로 하여 한국관광개발공사법에 의하여 설립된 법인인 사실, 1974년경 건설부 주관하에 경주보문관광단지의 개발사업이 착수되자 피고 공사는 같은 해 8.6. 원고를 포함한 10여 명의 소속 직원들을 건설부경주개발사무소에 파견하여 경주 현장에서 근무하게 하다가, 같은 해 10.25. 피고 공사의 개발부 산하에 경주연락사무소를 신설하고 원고 등 경주현장 파견직원들을 위 경주연락사무소 소속직원으로 계속 근무케 하던 중 1975.7.경 위 경주보문관광단지의 개발사업이 일단락되고, 7.25. 위와 같이 정부 주관하에 건설된 경주보문단지를 인수, 관리하고 이를 국제수준의 종합관광단지로 개발 유지하기 위하여 소외 주식회사 경주관광개발공사(이하 소외 회사라고 함)가 별개의 법인으로 설립되게 된 사실, 이에 소외 회사는 피고 공사의 도움아래 직원을 모집하게 되었는데 당시 피고 공사에서 기능직사원으로 근무하고 있던 원고는 사무직으로 직종변경을 하여 사무직으로 근무할 수 있으면 소외 회사로 가겠다는 의사표시를 하고 소외 회사가 이를 받아들임으로써 원고는 1975.7.31. 피고 공사에 사직서를 제출하고 퇴직금을 수령하여 피고 공사를 퇴직하고 그 다음날부터 소외 회사에서 사무직사원으로 근무한 사실, 그 후 원고는 1977.3.경 피고 공사에서 경력직사원을 모집함을 알고 1977.3.31. 소외 회사에 사직서를 제출하여 퇴직하고 같은 해 4.1. 피고 공사에 재입사하여 사무직으로 계속 근무하다가 1989.10.17. 피고 공사를 퇴직한 사실 등을 인정한 다음, 원고의 위 1975.7.31.자 피고 공사에서의 퇴직이 원고에게 어떤 불이익이나 불합리한 대우를 한 것이라기보다 오히려 원고에게 사무직사원으로서의 근무라는 유리한 대우를 한 것이고, 이로 인하여 근로기준법을 잠탈할 목적이 있다던가 신의칙이나 사회정의 및 형평에 반한 것이라는 비난가능성이 인정되지 않는 이상, 원고의 위 퇴직의 의사표시는 자발적인 의사에서 한 법률행위로 봄이 상당하므로 위 퇴직 및 재입사가 통정허위표시이거나 근로기준법 위반으로 무효로 볼 수 없고, 따라서 퇴직금 산정에 관한 근속기간은 재입사 시점인 1977.4.1.부터 진행한다고 판단하였는 바, 원심의 위와 같은 사실인정과 판단은 수긍이 되고 소론과 같은 채증법칙위배의 위법이나 근속기간 산정에 관한 법리오해의 위법이 있다고 할 수 없다. 논지는 이유 없다.

2. 원심은 그 판결이유에서 1981.1.1.자로 개정된 피고 공사의 퇴직금지급규정은 종전 규정의 적용을 받고 있던 근로자들에게 판시와 같이 불이익하게 변경된 것이고 그 변경에 관하여 이들 근로자의 집단의사결정방법에 의한 동의가 없었으므로 위 개정된 퇴직금지급규정은 무효라고 할 것이나, 한편 피고 공사의 근로자들은 개정된 퇴직금지급규정이 자신들에게 불리한 것으로서 무효임을 인식하고 있었음에도 그것이 장기간 이의 없이 시행되어 왔던 탓에 원고를 비롯한 피고 공사 소속 근로자들로 조직된 노동조합이 1984.12.31. 피고 공사와 단체협약을 체결함에 있어 위와 같이 불리하게 개정된 퇴직금지급규정과 동일한 내용의 퇴직금규정을 마련한 것이므로, 이는 무효인 위 퇴직금지급규정을 유효한 것으로 받아들임과 동시에 그 소급적용을 추인한 경우에 해당된다고 하여 원고에게도 개정된 퇴직금지급규정이 적용되어야 한다고 판단하였다.

그러나 원고가 위 노동조합에 가입하였다고 인정할 만한 자료가 없을 뿐만 아니라(을 제5호증의 1, 제6호증의 1 참조) 피고 공사의 근로자들이 위 단체협약의 체결 당시 개정된 퇴직금지급규정이 위와 같은 사정으로 무효임을 인식하고 있었다는 점을 인정할만한 증거도 찾아 볼 수 없다. 그렇다면 위 퇴직금지급규정의 개정이 사후의 소급적인 추인에 의하여 유효하게 되었다고 볼 수는 없으므로 이와 배치되는 원심판단은 채증법칙을 위배하여 사실을 오인하고 심리를 다하지 아니한 위법을 저지른 것이라고 할 것이다. 이 점에 관한 논지는 이유 있다.

이상의 이유로 원심판결을 파기하고 사건을 원심법원에 환송하기로 하여 관여 법관의 일치된 의견으로 주문과 같이 판결한다.
