This case concerned whether inciting workers to collectively refuse overtime work (연장근로) that they had customarily performed constituted a labor dispute action (쟁의행위) under Korean law. The Supreme Court held that even if the overtime arrangement was based on mutual agreement, organizing a collective refusal that disrupted the company's normal operations qualified as a labor dispute action. Because this action was carried out without following the legally required procedures, the Court confirmed a violation of the Labor Dispute Mediation Act (노동쟁의조정법).

Key takeaways
  • CaseA union member incited workers to collectively refuse to perform overtime work they had routinely done, without following legal dispute procedures.
  • OutcomeThe Supreme Court ruled that this collective refusal constituted an unlawful labor dispute action, finding a violation of the Labor Dispute Mediation Act.
  • LessonEven agreed-upon work arrangements like overtime can trigger legal labor dispute obligations if refused collectively to pressure the employer, so proper dispute procedures must be followed.
Issues
  • Whether a collective refusal to perform customary overtime work qualifies as a labor dispute action (쟁의행위)
  • Whether a labor dispute action conducted without following lawful procedures is unlawful
  • Whether the elements of obstruction of business (업무방해) and assault (폭행) were established
Key reasoning

The Court reasoned that the legal characterization of an action as a labor dispute action (쟁의행위) depends on its practical effect on business operations, not merely on the formal basis of the underlying work arrangement. Even though the overtime work had originally been agreed upon by both labor and management, inciting workers to collectively and suddenly refuse to perform it—work they had been doing as a matter of routine—effectively disrupted the employer's normal business operations. Such collective action, by its nature and impact, falls within the definition of a labor dispute action requiring compliance with statutory procedures. Since the defendant organized this refusal without following the lawful dispute resolution procedures mandated by the Labor Dispute Mediation Act, the act constituted an unlawful labor dispute action in violation of the statute.

Summary of Decision (English, AI translation)

Even if overtime work is performed based on an agreement between the parties, if a person incites workers to collectively refuse the overtime work that they have customarily performed, thereby impeding the normal operation of the company's business, this must be regarded as an industrial action (쟁의행위).

[Lower Court Decision]

Masan District Court Decision 90No968, rendered on February 6, 1991

[Order]

The appeal is dismissed.

[Reasoning] The grounds of appeal are examined.

As to the violation of the Labor Dispute Mediation Act (노동쟁의조정법),

Upon examining the evidence cited in the lower court's judgment and the first instance judgment cited therein against the record, the lower court's action in finding each of the criminal facts stated in the judgment—that the Defendant engaged in industrial action without going through lawful procedures—can be accepted, and it cannot be said that there was a misapprehension of facts due to a violation of the rules of evidence.

Even if extended work is something that is carried out by agreement between the parties, if the Defendant incited workers to collectively refuse the extended work that they had customarily performed, thereby impeding the normal operation of the company's business, this must be regarded as industrial action.

Further, even if there existed, as the argument contends, circumstances in the cause of the industrial action that could be attributed to the responsibility of the employer side, this does not mean that the criminal acts stated in the judgment fail to be established.

The remaining arguments raised in the argument ultimately amount to criticizing the fact-finding, which is a matter within the exclusive authority of the lower court (according to the record, it can be seen that the Defendant confessed to all of the facts charged in this portion at the first trial date of the first instance), and are therefore without merit.

As to the point of obstruction of business,

Upon examining the record, the lower court's fact-finding on this point can also be accepted, and even if such conduct was intended to strengthen the solidarity of the union, this does not constitute an obstacle to the lower court's fact-finding or to the establishment of the crime of obstruction of business.

As to the point of assault,

Upon examining the record, the lower court's action in finding the criminal facts—that the Defendant assaulted the victim as stated in the judgment, on the grounds of restraining the Defendant's conduct of disrupting operations by beating a gong (kkwaenggari) during working hours—is justified and can be accepted, and such conduct cannot be regarded, as the argument contends, as legitimate self-defense.

In the end, since none of the grounds of appeal have merit, the appeal is dismissed, and it is so decided as stated in the Order by the unanimous opinion of the participating Justices.

【판결요지】

연장근로가 당사자 합의에 의하여 이루어지는 것이라고 하더라도 근로자들을 선동하여 근로자들이 통상적으로 해 오던 연장근로를 집단적으로 거부하도록 함으로써 회사업무의 정상운영을 저해하였다면 이는 쟁의행위로 보아야 한다.

상고를 기각한다.

【이 유】 상고이유를 판단한다.

노동쟁의조정법위반의 점에 대하여,

원심판결 및 원심이 인용한 제1심 판결이 들고 있는 증거들을 기록에 비추어 검토하면, 피고인이 적법한 절차를 거치지 아니하고 쟁의행위를 하였다는 판시 각 범죄사실을 인정한 원심의 조치는 수긍할 수 있고, 이에 채증법칙위배로 인한 사실오인이 있다고 할 수없다.

연장근로가 당사자 합의에 의하여 이루어지는 것이라고 하더라도 근로자들을 선동하여 근로자들이 통상적으로 해 오던 연장근로를 집단적으로 거부하도록 함으로써 회사업무의 정상운영을 저해하였다면 이는 쟁의행위로 보아야 할 것이다.

또 쟁의행위의 원인에 있어 사용자 측에 책임을 돌릴 만한 소론주장의 사유가 있다 하더라도 이로써 판시 범행이 성립하지 아니하는 것은 아니다.

그밖에 소론이 내세우는 주장은 원심의 전권사항인 사실인정을 비난함에 귀착되어(기록에 의하면 피고인은 제1심 제1회 공판기일에 이 부분 공소사실을 모두 자백하였음을 엿볼 수 있다.) 이유없다 할 것이다.

업무방해의 점에 대하여,

기록에 비추어 살펴보면, 이 부분에 대한 원심의 사실인정도 수긍할 수 있고, 그와 같은 행위가 조합의 결속력을 강화하기 위한 것이라고 하더라도 원심의 사실인정이나 업무방해죄의 성립에 장애가 된다고 할 수 없다.

폭행의 점에 대하여,

기록에 비추어 보면, 조업시간중에 꽹가리를 치며 조업을 방해하는 피고인의 행위를 제지한다는 이유로 피고인이 판시와 같이 피해자를 폭행하였다는 범죄사실을 인정한 원심의 조치는 정당하여 수긍할 수 있으며, 또 그와 같은 행위를 소론과 같이 정당방위로 볼 수는 없는 것이다.

결국 논지는 모두 이유없으므로 상고를 기각하기로 하여 관여 법관의 일치된 의견으로 주문과 같이 판결한다.
