A surprising number of foreign workers in Korea assume that if their employer wants them gone, there's nothing to be done about it — especially if their visa is tied to that job. That assumption is usually wrong. Korean labor law places real limits on when and how an employer can dismiss someone, and those protections generally apply regardless of nationality or visa status. The catch is that the process to challenge an unfair dismissal (부당해고) moves on a short clock, so knowing your rights early matters more than it would in a system with a longer statute of limitations.

1Korea Doesn't Have "At-Will" Employment

Under the Labor Standards Act (근로기준법), employers generally need "justifiable cause" (정당한 이유) to dismiss an employee — a documented, substantial reason such as serious misconduct or a legitimate business-necessity layoff carried out through the proper procedure. Firing someone simply because business is slow, because a manager wants a change, or without following required procedure can be ruled an unfair dismissal (부당해고), regardless of the worker's nationality or visa type.

2The 5-Employee Threshold

Full unfair dismissal (부당해고) protection generally applies to workplaces with 5 or more employees. Smaller workplaces have narrower protection against the dismissal itself, though other Labor Standards Act (근로기준법) protections — like severance pay and notice requirements — generally still apply regardless of company size.

3Notice Requirements Even When Dismissal Is Valid

Even a lawful dismissal generally requires 30 days' advance notice, or payment in lieu of notice (해고예고수당) if the employer skips that notice period. This is a separate legal requirement from whether the dismissal itself was justified — an employer can have valid cause to dismiss you and still owe you notice pay for failing to give proper notice.

4Filing With the Labor Relations Commission (노동위원회)

If you believe your dismissal was unfair, you can file for remedy with the Labor Relations Commission (노동위원회) — an administrative body, not a court — within 3 months of the dismissal date. This route is generally faster and less procedurally demanding than civil litigation, and you don't need to already have a lawyer to file the initial claim.

The 3-month clock for filing with the Labor Relations Commission (노동위원회) runs from the dismissal date itself — not from your last paycheck, and not from when you find new work.

5What Remedies Look Like

If the commission finds the dismissal unfair, it can order reinstatement (원직복직) along with back pay for the period you were out of work. In practice, many cases resolve through a monetary settlement covering back pay rather than actual reinstatement — particularly once the working relationship has clearly broken down and neither side wants to continue it.

6Visa Status Complicates the Timeline, Not the Right

Being on an employer-sponsored visa (E-7, E-9, and similar categories) doesn't remove your right to challenge a dismissal through the Labor Relations Commission (노동위원회). But losing your job can affect your visa status while the case is still pending, so it's worth thinking through your visa options — a grace period, a status change, or another sponsor — in parallel with the labor claim rather than after it's resolved.

→If You've Just Been Let Go

  1. Get the dismissal in writing — a purely verbal firing, without a written notice of dismissal, can itself be a procedural violation.
  2. Note the exact date — the 3-month filing deadline for an unfair dismissal (부당해고) claim runs from that day, not from your final paycheck.
  3. Gather your employment contract, pay stubs, and any messages that reference the reason given for the dismissal.
  4. Get advice before signing anything presented as a "resignation" — a resignation you didn't actually intend to submit can undermine a later unfair dismissal (부당해고) claim.

→A Note for Latin American Clients

The absence of at-will employment in Korea often comes as a genuine surprise to clients from Latin America, where dismissal norms work differently. I help foreign workers evaluate whether a dismissal was unfair, prepare and file claims with the Labor Relations Commission (노동위원회), and think through the visa timeline alongside the labor case — in Spanish or Portuguese.
