This Supreme Court ruling established that when a collective bargaining agreement (단체협약) exhaustively and restrictively lists the grounds for disciplinary dismissal, an employer cannot dismiss an employee for reasons outside that list. It also established the principle that when calculating wages owed for a period of unfair dismissal (부당해고), any interim income earned by the employee elsewhere must be deducted from the back pay, but only the portion exceeding the statutory suspension allowance (휴업수당) amount may be deducted — the suspension allowance portion itself is protected and cannot be offset.

Key takeaways
  • CaseA company disciplinarily dismissed an employee for reasons not specified in the collective bargaining agreement, and sought to deduct the employee's entire interim income from the back pay owed for the wrongful dismissal period.
  • OutcomeThe Court ruled that dismissal grounds not listed in the collective bargaining agreement cannot justify disciplinary dismissal, and that when deducting interim income from back pay, the amount equivalent to the suspension allowance must be excluded from deduction.
  • LessonEmployers must strictly adhere to the dismissal grounds specified in collective bargaining agreements, and when deducting interim income after an unfair dismissal, only the portion exceeding the suspension allowance is deductible.
Issues
  • Whether an employer may disciplinarily dismiss an employee for reasons not included in a collective bargaining agreement that restrictively enumerates dismissal grounds
  • The permissible scope of deducting interim income from back wages owed following an unfair dismissal
Key reasoning

The Court held that where a collective bargaining agreement specifically and restrictively enumerates the grounds for disciplinary dismissal, this list operates as an exhaustive limit on the employer's disciplinary power. Consequently, the employer may not dismiss an employee for any reason not explicitly included in that list, even if such other reasons might otherwise seem justifiable. Separately, on the issue of back pay calculation following a wrongful dismissal, the Court reasoned that the suspension allowance (an amount guaranteed to workers who are unable to work through no fault of their own, typically 70% of average wages) represents a minimum guaranteed income that must remain protected. Therefore, when offsetting the employee's interim earnings (income earned from other work during the wrongful dismissal period) against the back pay owed, only the portion of interim income exceeding the suspension allowance threshold may be deducted, ensuring the employee retains at least the suspension allowance amount.

Summary of Decision (English, AI translation)

a. Where a collective agreement or rules of employment enumerates in a limited manner the grounds for disciplinary dismissal of an employee, the employer may not dismiss the employee on grounds other than those so enumerated.

b. Wages that an employee, dismissed due to grounds attributable to the employer, receives from working at another workplace during the period of dismissal constitute a benefit obtained by being released from his own obligation as provided in Article 538(2) of the Civil Act (민법). Accordingly, the employer, in paying the employee's wages for the period of dismissal, may deduct such benefit (so-called intermediate income); however, the portion of the wages that the employee would have been entitled to receive which falls within the scope of the leave allowance (休業手當) prescribed under Article 38 of the Labor Standards Act (근로기준법) may not be deducted as intermediate income, and only the amount exceeding the leave allowance may be deducted as intermediate income.

[Plaintiff, Appellee]

[Defendant, Appellant] Bowon Oil Tank (普元油槽) Co., Ltd., Attorney Seo Yong-eun, Litigation Representative

[Judgment Below] Seoul High Court Judgment 92Na56706, decided June 18, 1993

[Order]

The appeal is dismissed.
The costs of the appeal shall be borne by the Defendant.

[Reasoning]

1. Determination on Ground No. 2 of the Defendant's Litigation Representative's grounds of appeal.

The court below found the following facts: The Plaintiff joined the Defendant company, which was a subcontractor for oil transportation for three companies including Honam Oil Refinery Co., Ltd., SK Corporation (Yukong Co., Ltd.), and Sebang Oil Co., Ltd., on December 8, 1988, and worked as a driver at the Defendant company's Incheon business office. On March 16, 1990, upon receiving a call that a friend's father had passed away, and in order to finish the oil delivery to Miwon Co., Ltd. that had been assigned to him for the following day early and go to pay respects at the funeral during the daytime, the Plaintiff came to work at the Defendant company's Incheon business office at around 01:35 on March 17, 1990, and drove out the tank truck (vehicle registration number omitted) without prior permission from the branch manager. At around 01:45, upon arriving at the Incheon oil storage depot of Honam Oil Refinery Co., Ltd. and entering the depot premises to load bunker C oil onto the tank truck, the Plaintiff negligently struck the movable roof structure installed at the depot with the front of the tank truck, causing damage amounting to 109,000 won at market price. The Plaintiff then drove the tank truck loaded with the bunker C oil and arrived at Miwon Co., Ltd. located in Banghak-dong, Dobong-gu, Seoul at around 04:15, where he made an excuse to the person in charge of the materials department of that company, a non-party, that he had to go handle the aforementioned accident, and begged them to conduct the inspection of the bunker C oil even though it was not normal working hours, and had the oil received. In response, Honam Oil Refinery Co., Ltd. sent an official document to the Defendant company around March 19, 1990, demanding compensation for the damage caused by the above accident, and as a sanction for the accident, suspended the Plaintiff's access to the above oil storage depot for one week from March 18 to March 24, while also demanding that thorough measures be taken to prevent recurrence of such an incident. Miwon Co., Ltd. also protested around that time against the request for late-night oil inspection made without prior consultation, and demanded prevention of recurrence of such an incident. The court below further found that Article 39 of the Defendant company's collective bargaining agreement (단체협약) sets forth grounds for dismissal, and that Article 39 lists 11 grounds for dismissal, including in item 1 "a person recognized by the union president as having poor work performance and showing no sign of repentance" and in item 3 "a person who intentionally causes a serious accident, thereby causing damage to the company," while also providing that dismissal may not be made on any grounds other than those enumerated above.

Having made the above findings, the court below determined that, even though the Plaintiff drove the vehicle without authorization and caused an accident, thereby causing damage to the Defendant company and causing the Defendant company to receive strong protests and reprimands from the aforementioned non-party companies, thereby significantly damaging the Defendant company's reputation, this alone, even taking into account the fact that the Plaintiff had caused accidents on two prior occasions, is insufficient to find that the Plaintiff intentionally caused the above accident. Therefore, the court below determined that this does not constitute grounds for disciplinary dismissal under Article 39, item 3 of the collective bargaining agreement, nor does it constitute any other ground for dismissal under Article 39 of the collective bargaining agreement.

Upon examination of the relevant evidence and the record, the above findings and determination of the court below are found to be justified and acceptable. Moreover, even if, as argued in the grounds of appeal, the Defendant obtained the consent of the labor union president in disciplinarily dismissing the Plaintiff, this cannot be viewed as making the Plaintiff's conduct fall under the grounds for disciplinary dismissal under Article 39, item 1 of the collective bargaining agreement. Furthermore, even if there were no procedural defects in the disciplinary dismissal as prescribed by the collective bargaining agreement and the employment rules, as argued in the grounds of appeal, this cannot be viewed as meaning that the disciplinary action falls within the private autonomy of the enterprise as an exercise of the employer's inherent disciplinary authority. Therefore, the argument that the judgment below erred in its assessment of evidence and misapprehended the legal principles concerning abuse of disciplinary authority and the private autonomy of enterprises cannot be accepted.

2. Determination on Ground No. 1 of the same grounds of appeal.

As argued in the grounds of appeal, "justifiable cause" under Article 27, Paragraph 1 of the Labor Standards Act (근로기준법), in the case of disciplinary dismissal, refers to circumstances attributable to the employee that are of such a nature that, in light of common social norms, the employment contract cannot be continued. However, where the grounds for disciplinary dismissal of an employee are exhaustively enumerated in a collective bargaining agreement or employment rules, disciplinary dismissal may not be made on any ground other than those so enumerated (see this Court's Judgment 91Da27518, decided May 12, 1992; Judgment 91Da27556, decided September 8, 1992, etc.). In the same vein, the determination of the court below that the Defendant company's disciplinary dismissal of the Plaintiff in this case was made without grounds and is therefore void is found to be justified and acceptable, and it cannot be said that the judgment below erred in its understanding of the legal principles concerning "justifiable cause" under Article 27, Paragraph 1 of the Labor Standards Act, as argued in the grounds of appeal. Therefore, this argument is also without merit.

3. Determination on Ground No. 3 of the same grounds of appeal.

Wages received by an employee who, having been dismissed due to a cause attributable to the employer, worked at another workplace during the period of dismissal, constitute a benefit obtained from being released from one's own obligation as prescribed in Article 538, Paragraph 2 of the Civil Act (민법), and accordingly, the employer may deduct such benefit (so-called "interim income") when paying wages for the period of dismissal to the employee. However, Article 38 of the Labor Standards Act, in order to guarantee the employee's basic livelihood, provides that where an employer suspends business operations due to a cause attributable to the employer, the employer shall pay the relevant employee an allowance of not less than 70/100 of the average wage during the period of suspension. The term "suspension of business" (휴업) under this provision includes cases where an employee, despite having the intent to provide labor in accordance with the labor contract, is unable to provide labor against his or her will. Therefore, among the amount of wages that the employee could have received, the amount within the scope of the suspension allowance under Article 38 of the Labor Standards Act may not be deducted as interim income, and only the amount exceeding the suspension allowance may be deducted as interim income. This is the view adopted in this Court's precedents (see Judgment 90Daka25277, decided June 28, 1991; Judgment 90Da18999, decided December 13, 1991, etc.).

The determination of the court below, which appears to have taken the same view as the above, is found to be justified and acceptable. Furthermore, the argument that, since the Plaintiff also received wages from the non-party Geukdong Transportation Co., Ltd. during the period of dismissal, such interim income should also be deducted from the amount of wages to be paid to the Plaintiff, is premised on new facts that were not asserted in the court below. Therefore, the argument that the judgment below erred in its understanding of the legal principles under Article 538, Paragraph 2 of the Civil Act cannot be accepted either.

4. Therefore, the Defendant's appeal is dismissed, and the costs of the appeal are to be borne by the Defendant, the losing party. This judgment is rendered as set forth in the Order, with the unanimous agreement of the participating Justices.

Justice Ahn Yong-deuk (Presiding Justice), Ahn Woo-man, Kim Yong-jun (Justice in charge), Cheon Gyeong-song

【이 유】 1. 피고 소송대리인의 상고이유 제2점에 대한 판단.

원심은, 원고는 1988.12.8. 호남정유 주식회사, 주식회사 유공, 세방석유 주식회사 등 3개 회사의 유류운송 하청업체인 피고 회사에 입사하여 피고 회사 인천영업소에서 운전기사로 근무하던 중, 1990.3.16. 친구가 부친상을 당하였다는 연락을 받게 되자 피고로부터 그 다음날 배차지시받은 주식회사 미원에의 유류배달을 일찍 끝마치고 낮에 문상을 가기 위하여, 1990.3.17. 01:35경 피고 회사 인천영업소에 출근하여 영업소장의 사전허락없이 (차량등록번호 생략) 유조차를 운행하고 나와 01:45경 호남정유주식회사 인천저유소에 도착하여 위 유조차에 벙커씨유를 적재하기 위하여 위 저유소 구내로 진입하다가 부주의로 위 유조차의 앞부분으로 위 저유소에 설치되어 있던 이동용 지붕구조물을 들이받아 시가 금109,000 상당의 손해를 입히는 사고를 냈으며, 이어서 벙커씨유를 적재한 위 유조차를 운전하여 04:15경 서울 도봉구 방학동 소재 주식회사 미원에 도착하여 위 회사 자재과 담당자 소외인 등에게 위 사고를 수습하러 가야한다는 핑계를 대고 정상근무시간은 아니지만 벙커씨유의 검수를 해 달라고 애원하여 이를 수납시킨 사실, 이에 대하여 호남정유 주식회사는 1990.3.19.경 피고 회사에게 위 사고로 인한 손해의 변상요구와 함께 위 사고에 대한 제재로 3.18.부터 3.24.까지 1주일간 원고의 위 저유소에의 출입을 정지함과 아울러 같은 사태의 재발방지에 만전을 기할 것을 요구하는 공문을 보내왔으며, 주식회사 미원도 그때쯤 사전협의없는 위 심야유류검수요구에 대한 항의와 함께 이러한 사태의 재발방지를 요구하여 온 사실, 피고 회사는 단체협약 제39조에서 해고사유를 규정하고 있는데, 단체협약 제39조는 제1호에 "근무성적이 불량하여 개전의 정이 없다고 인정되는 자로서 조합장이 인정하는 자", 제3호에 "고의로 중대한 사고를 발생시켜 회사에 손해를 끼친 자" 등 11개의 사유를 해고사유로 규정함과 동시에 위에서 열거된 사유 외에는 해고할 수 없다고 규정하고 있는 사실 등을 인정한 다음, 위에서 인정한 바와 같이 비록 원고가 무단으로 차량을 운행하다가 사고를 야기시켜 피고 회사에게 손해를 끼침과 아울러 위 소외회사들로부터 강력한 항의와 질책을 받게 함으로써 피고 회사의 명예를 크게 손상시켰다는 것만으로는, 과거 원고가 두차례에 걸쳐 사고를 야기시킨 점을 감안하더라도 원고가 고의로 위 사고를 발생시켰다고 보기에 부족하므로, 단체협약 제39조 제3호 소정의 징계해고사유에 해당하지 아니함은 물론 그외 단체협약 제39조 소정의 다른 해고사유에 해당한다고도 볼 수 없다고 판단하였다.

관계증거와 기록에 의하면 원심의 위와 같은 인정판단은 정당한 것으로 수긍이 될 뿐만 아니라, 피고가 원고를 징계해고함에 있어서 소론과 같이 노동조합장의 동의를 받았다고 하더라도 원고가 단체협약 제39조 제1호 소정의 징계해고사유에 해당하는 것으로 볼 수 없음은 물론, 소론과 같이 징계해고처분에 단체협약과 취업규칙에 규정된 절차상의 하자가 없는 이상 그 징계처분이 사용자의 고유의 징계권의 행사로서 기업내부의 사적자치에 속하는 것이라고 볼 수도 없으므로, 원심판결에 증거를 잘못 판단하여 징계권의 남용에 관한 법리 및 기업의 사적자치에 관한 법리를 오해한 위법이 있다는 논지는 받아들일 수 없다.

2. 같은 상고이유 제1점에 대한 판단.

근로기준법 제27조 제1항 소정의 "정당한 이유"란 징계해고의 경우에는 사회통념상 근로계약을 존속시킬 수 없을 정도로 근로자에게 책임있는 사유가 있는 것을 말하는 것임은 소론과 같지만, 단체협약이나 취업규칙에 근로자에 대한 징계해고사유가 제한적으로 열거되어 있는 경우에는 그와 같이 열거되어 있는 사유 이외의 사유로는 징계해고할 수 없는 것이므로( 당원 1992.5.12. 선고 91다27518 판결; 1992.9.8. 선고 91다27556 판결 등 참조), 같은 취지에서 피고 회사의 원고에 대한 이 사건 징계해고처분이 근거없이 이루어진 것이어서 무효라고 본 원심의 판단은 정당한 것으로 수긍이 되고, 원심판결에 소론과 같이 근로기준법 제27조 제1항 소정의 정당한 이유 등에 관한 법리를 오해한 위법이 있다고 볼 수 없으므로, 논지도 이유가 없다.

3. 같은 상고이유 제3점에 대한 판단.

사용자의 귀책사유로 인하여 해고된 근로자가 해고기간중에 다른 직장에서 근무하여 지급받은 임금은 민법 제538조 제2항에 규정된 자기의 채무를 면함으로써 얻은 이익에 해당하므로, 사용자는 근로자에게 해고기간중의 임금을 지급함에 있어 위와 같은 이익(이른바 중간수입)을 공제할 수 있는 것이기는 하지만, 근로기준법 제38조가 근로자의 기본적생활을 보장하려는 취지에서 사용자의 귀책사유로 인하여 휴업하는 경우에는 사용자는 휴업기간중 당해 근로자에게 평균임금의 100분의 70 이상의 수당을 지급하여야 한다고 규정하고 있고, 이 규정에서의 "휴업"에는 근로자가 근로계약에 따라 근로를 제공할 의사가 있음에도 불구하고 그 의사에 반하여 근로를 제공할 수 없게 된 경우도 포함된다고 할 것이므로, 근로자가 지급받을 수 있는 임금액중 근로기준법 제38조 소정의 휴업수당의 범위내의 금액은 중간수입으로 공제할 수 없고, 휴업수당을 초과하는 금액만을 중간수입으로 공제하여야 한다 는 것이 당원의 판례( 1991.6.28. 선고 90다카25277 판결; 1991.12.13. 선고 90다18999 판결 등)가 취하고 있는 견해이다.

이와 견해를 같이 한 것으로 보이는 원심의 판단은 정당한 것으로 수긍이 될 뿐만 아니라, 원고가 해고기간중에 소외 극동운수 주식회사로부터도 임금을 받고 있었으므로 그 중간수입액도 원고에게 지급될 임금액에서 공제하여야 한다는 소론은 원심에서 주장되지 아니한 새로운 사실을 전제로 하는 것이므로, 원심판결에 민법 제538조 제2항의 법리를 오해한 위법이 있다는 논지도 받아들일 수 없는 것이다.

4. 그러므로 피고의 상고를 기각하고 상고비용은 패소자인 피고의 부담으로 하기로 관여 법관의 의견이 일치되어 주문과 같이 판결한다.
