How Do We Defend an Unfair Dismissal Claim in Korea?

Short Answer

To defend an unfair dismissal claim in Korea, the employer must generally show two things.

First, the dismissal was supported by a justifiable reason.

Second, the employer followed the required procedures, including proper written notice of the dismissal reason and dismissal date.

In practice, Korean labor authorities and courts examine not only why the employee was dismissed, but also how the employer investigated, decided, documented, and notified the dismissal.

For foreign companies, the strongest defense usually depends on a clear case theory, contemporaneous evidence, and careful management of the Labor Relations Commission process.

What Is an Unfair Dismissal Claim?

An unfair dismissal claim is a legal challenge by an employee arguing that the dismissal lacked a justifiable reason or failed to comply with legal procedures.

In Korea, many unfair dismissal disputes are first handled before the Labor Relations Commission.

If the employee succeeds, the employer may face reinstatement, back pay, monetary compensation, or other remedial orders.

What Is the First Step in Defending the Claim?

The first step is to identify the exact type of dismissal.

Employers should determine whether the case involves:

• disciplinary dismissal for misconduct;
• ordinary dismissal for poor performance or lack of ability;
• redundancy or business-related dismissal;
• refusal to renew a fixed-term contract;
• probationary dismissal; or
• a disputed resignation that the employee claims was actually dismissal.

This classification matters because the legal standards, required evidence, and defense strategy may differ.

---

What Must the Employer Prove?

The employer should be prepared to prove:

• the specific reason for dismissal;
• why that reason was legally sufficient;
• what evidence supports the reason;
• whether the employer followed internal procedures;
• whether the employee had an opportunity to respond where required;
• whether the written termination notice was properly issued; and
• whether the decision was proportionate under the circumstances.

A dismissal is not defended by conclusion alone.

The employer must be able to connect the facts, evidence, procedure, and final decision.

---

Why Is the Written Termination Notice Important?

The written termination notice is often one of the most important documents in the case.

Under Korean labor law, a dismissal generally must be notified in writing, and the written notice should state both:

• the reason for dismissal; and
• the effective date of dismissal.

A defective notice can seriously weaken the employer’s case, even where the employer believes there was a valid reason for dismissal.

The notice does not necessarily need to have a specific title, but the employee should be able to understand the actual reason for dismissal from the written document.

---

Can the Employer Add New Reasons Later?

This is risky.

In dismissal disputes, the employer’s defense is generally evaluated based on the reasons actually relied upon at the time of dismissal.

If the employer later attempts to add new reasons that were not part of the original decision, the employee may argue that the company is trying to justify the dismissal after the fact.

For this reason, employers should identify the dismissal grounds carefully before issuing the termination notice.

---

What Evidence Is Most Important?

The most important evidence is usually evidence created before the dispute arose.

Helpful evidence may include:

• investigation reports;
• disciplinary committee records;
• written warnings;
• performance evaluations;
• attendance records;
• emails and internal messages;
• witness statements;
• meeting minutes;
• policy acknowledgements;
• CCTV or system logs where lawfully collected;
• prior coaching or improvement records; and
• written termination notices.

Contemporaneous records are generally more persuasive than documents created after the employee files a claim.

How Do We Defend a Misconduct-Based Dismissal?

For misconduct-based dismissal, the employer should focus on:

• what misconduct occurred;
• how it was discovered;
• what evidence supports it;
• whether the employee was given a chance to explain;
• whether the misconduct violated company policies;
• whether dismissal was proportionate; and
• whether similar cases were handled consistently.

Even where misconduct is proven, dismissal may still be challenged if the sanction is viewed as excessive.

The employer should therefore explain why continued employment became difficult under the circumstances.

---

How Do We Defend a Poor Performance Dismissal?

Poor performance dismissals require careful preparation.

Employers should be ready to show:

• objective performance standards;
• repeated or significant underperformance;
• fair evaluations;
• feedback or warnings;
• training or improvement opportunities where appropriate;
• consideration of reassignment or alternative measures where relevant; and
• why continued employment was no longer reasonable.

A vague statement that the employee was “not performing well” is usually weak.

The stronger defense is built on objective evaluation records and a documented improvement process.

---

Why Does Procedure Matter So Much?

Procedure can determine the outcome.

Even where the employer has a strong factual reason, procedural defects may undermine the dismissal.

Employers should review:

• employment contracts;
• work rules;
• disciplinary procedures;
• collective agreements, if any;
• notice requirements;
• disciplinary committee requirements;
• employee hearing or explanation opportunities; and
• internal approval requirements.

If the company’s own rules require a specific process, failure to follow that process may create substantial risk.

---

What Happens in the Labor Relations Commission Process?

In a Labor Relations Commission case, the parties generally submit arguments and evidence, and a hearing is held.

The Commission examines whether the dismissal was justified and whether proper procedures were followed.

The employer should prepare:

• a clear chronology;
• a list of key issues;
• supporting documents;
• witness or manager statements where appropriate;
• explanation of internal procedures; and
• a response to the employee’s main arguments.

The employer should also track procedural deadlines carefully.

---

What Remedies Can Be Ordered?

If the dismissal is found unfair, the employer may be ordered to reinstate the employee and pay wages that would have been earned during the dismissal period.

In some cases, monetary compensation may be ordered instead of reinstatement.

If the employer fails to comply with a final remedial order, additional enforcement consequences may arise.

This is why defense strategy should consider not only whether the employer can win, but also the practical risk of reinstatement, back pay, settlement, and compliance with any order.

Practical Checklist for Foreign Companies

When defending an unfair dismissal claim in Korea, employers should immediately review:

• What type of dismissal is being challenged?
• What reason was stated in the written notice?
• Was the dismissal reason specific enough?
• Was the effective date clearly stated?
• Were internal procedures followed?
• Was the employee given an opportunity to respond where required?
• What contemporaneous evidence supports the decision?
• Are there any procedural defects?
• Are there deadlines for response, appeal, or litigation?
• What is the potential exposure if the dismissal is found unfair?

Early case assessment is critical.

---

Practical Takeaway

An unfair dismissal defense is not just about proving that the employee did something wrong.

The employer must show that the dismissal was legally justified, procedurally proper, and supported by evidence that existed at the time of the decision.

For foreign companies, a clear defense strategy should be built around the stated dismissal reason, the written notice, the internal procedure, and the contemporaneous evidentiary record.

---

Conclusion

Defending an unfair dismissal claim in Korea requires a structured approach.

Employers should first identify the type of dismissal, confirm the written grounds, review procedural compliance, preserve evidence, and prepare a clear explanation of why the dismissal was justified.

Because Korean authorities examine both substance and procedure, foreign companies should treat dismissal defense as a legal, HR, and evidentiary exercise from the very beginning of the dispute.
