    1. Legal Implications

    Ⅰ. Case Overview

    In this case, after the employee submitted a resignation letter and was subsequently dismissed following disciplinary procedures, the employee claimed unfair dismissal and applied for relief to the Labor Relations Commission.

    The Commission focused on: (i) whether the employment contract was still in force at the time of the disciplinary action; (ii) the legitimacy of the grounds for discipline and the level of disciplinary sanction; and (iii) whether defects in the disciplinary procedure could be cured. It ultimately accepted the employer’s arguments and dismissed the employee’s application.

    Ⅱ. Summary of Issues

    The issues in this case were whether: (i) a disciplinary dismissal imposed while a resignation letter had been submitted was still premised on a valid employment contract; (ii) the grounds for discipline differed from prior disciplinary grounds such that the action did not constitute double jeopardy; and (iii) even if there were some defects in the disciplinary procedure, those defects were cured by the employee’s attendance at the Personnel Committee and opportunity to explain, so that the dismissal did not amount to unfair dismissal.

    Ⅲ. Summary of the Labor Relations Commission’s Findings

    The adjudicating panel took into account that the employer had not accepted the resignation letter submitted by the employee; that Ground for Discipline 1 differed from the grounds for the prior suspension and therefore did not constitute double jeopardy; that all other grounds for discipline (Ground for Discipline 2) were also recognized; that, in light of the nature and seriousness of the grounds for discipline, the level of disciplinary sanction could not be regarded as manifestly excessive by social standards; and that, although there were some defects in the disciplinary procedure, those defects were cured because the employees attended the Personnel Committee and were given a sufficient opportunity to explain.

    Accordingly, the panel held that the dismissal in this case did not suffer from any serious or fundamental illegality in terms of the existence of grounds for discipline, the level of disciplinary sanction, or the disciplinary procedure, and that the employer had satisfied its burden of proof to show just cause. The dismissal was therefore found not to constitute unfair dismissal.

    Ⅳ. Practical Points (From the Employee’s Perspective)

    Employees should note that, even if they submit a resignation letter, the employment contract continues to exist and they may still be subject to disciplinary procedures unless and until the employer clearly accepts the resignation.

    In addition, even if an employee has previously been disciplined (e.g., suspension), if a separate subsequent act of misconduct occurs, the employee may again be subject to discipline. One should not assume that “because I was disciplined once before, the same type of discipline cannot be imposed again.”

    Ⅴ. Practical Points (From the Employer/Company Perspective)

    From the employer’s standpoint, to secure the legitimacy of a disciplinary dismissal, it is necessary to prepare concrete evidence showing that: (i) the grounds for discipline fall within the disciplinary grounds set out in the rules of employment, collective agreement, etc.; and (ii) the grounds are so serious that, by social standards, it is difficult to maintain the employment relationship.

    In the disciplinary procedure, the employer should comply with the prescribed procedures, such as prior notice, providing an opportunity to attend, and an opportunity to explain. At the same time, even if some defects in notice or procedure occur, those defects may be cured if the employee attends the Personnel Committee and provides an explanation without objection. Employers should therefore carefully keep minutes, attendance records, and the contents of the employee’s explanation.

    This decision is a useful example of how, in unfair dismissal disputes, the Labor Relations Commission comprehensively examines: (i) whether the employment contract was still in force; (ii) whether the case constitutes double jeopardy; (iii) the scope of discretion in setting the level of disciplinary sanction; and (iv) the possibility of curing defects in the disciplinary procedure. In similar cases, it is advisable for both employees and employers to consult with a specialized institution such as Labor Law Firm Law& to thoroughly organize the facts and legal issues.
