Unpaid Wages: Labor Office vs. Lawsuit

Unpaid wages in Korea are common enough to have a whole enforcement system of their own — and that is the first thing to understand if your salary has stopped arriving: you are not suing a company from scratch. The Labor Standards Act (근로기준법) makes paying you a legal duty backed by criminal penalties, a government inspectorate exists to enforce it, and a public fund exists to pay you when the employer cannot.

The practical question is not whether you have rights but which track to use: the labor office complaint (진정), the civil lawsuit, or — as it usually plays out — the complaint first, feeding everything else. This guide walks the tracks in the order that works, with the numbers and deadlines attached.

1. The rules your employer already broke

• Wages must be paid in full, directly, in currency, on a fixed dayat least monthly (Labor Standards Act art. 43). “Sales were bad this month” is not a legal category.
• The 14-day settlement rule. When you quit, are fired, or the contract ends, every amount owed — final wages, statutory severance, unused annual-leave pay — is due within 14 days (art. 36), extendable only by genuine agreement.
• 20% interest. Miss the 14 days and unpaid wages and severance for a departed worker carry interest at 20% per year until paid (art. 37).
• It is a crime. Non-payment is punishable by up to 3 years imprisonment or a ₩30 million fine (art. 109). The offense cannot be prosecuted against your expressed wish — which quietly makes yoursignature on a settlement the employer’s exit from criminal exposure. That is leverage; spend it only in exchange for money.
• Three years. Wage claims expire 3 years after each payment fell due (art. 49).

2. Two tracks — and the order that works

These are not rivals. The sequence that works for most people: complain to the labor office first — it is free, fast, and most employers pay under criminal pressure — and let its confirmation document power the wage fund and, if needed, a lawsuit that someone else pays for.

3. The labor office complaint, step by step

1. 1

   File the complaint

   Online through the Ministry of Employment and Labor's Labor Portal, or in person at the labor office covering the workplace. Filing is designed for workers to do themselves — no representative is required.
2. 2

   The labor inspector investigates

   Both sides are summoned and questioned; bring your evidence (section 6). The inspector establishes what is owed and orders correction.
3. 3

   Most cases end here — with payment

   Faced with an official arrears figure and criminal referral, most employers pay or settle in installments in writing.
4. 4

   If not: confirmation document + criminal referral

   The office issues the wage-arrears confirmation — your key to the fund and free legal aid — and refers the employer for prosecution.

4. When the employer won’t pay: the wage fund

Korea’s wage-guarantee system pays workers first and collects from the employer afterward. The version most workers use, the simplified advance payment (간이대지급금), covers up to ₩7 million of the last 3 months’ wages and ₩7 million of the last 3 years’ severance — ₩10 million combined— and does not require the company to be bankrupt. It is claimed from the Korea Workers’ Compensation & Welfare Service on the strength of either the labor office’s confirmation document or a court judgment.

The windows are tight and worth writing down: on the confirmation route, the complaint must be filed within 1 year of leaving the job and the fund claimed within 6 months of the confirmation’s issuance; on the judgment route, suit must be filed within 2 years of leaving and the fund claimed within 1 year of the final judgment. A separate, larger version of the fund exists for genuinely insolvent employers.

5. The lawsuit — and free legal aid

The civil route matters when the amounts exceed the fund’s ceiling, when the employer disputes the debt itself, or when you need a judgment to seize assets. Claims of ₩30 million or less travel the simplified small-claims track. Interest keeps running — the 20% rate for a departed worker’s wages and severance — and a final judgment can be enforced against the employer’s bank accounts and property.

Here is the fact that changes the economics: workers whose average monthly wage over the final three months was under ₩4 million qualify for free legal aid through the Korea Legal Aid Corporation — consultation and the lawsuit itself, at no cost, and the program explicitly includes foreign residents. The path runs through the labor office confirmation document, then an application to the Corporation (helpline 132). For most unpaid-wage cases at ordinary salaries, in other words, the lawsuit does not cost you a lawyer.

6. Common mistakes

The complaint is only as strong as the records behind it — contract, payslips, schedules, bank statements, and the messages where pay was discussed.

• Working months on promises. Every unpaid month ages toward the 3-year cliff and deepens your exposure to a failing company. Two missed paydays is a pattern, not an accident.
• Quitting without securing the records. Contract, payslips, timesheets or shift schedules, bank statements, and the messages where work and pay were discussed — collect them while you still have access. No written contract does not kill the claim; evidence of the work and the promised rate carries it.
• Signing away leverage for promises— the withdrawal-before-payment trap in section 3, and its cousin, accepting a partial payment “in full settlement.”
• Letting visa worries stop you from filing. Wages for work already performed are treated as claimable in practice regardless of your status situation, and labor offices routinely handle complaints from foreign workers. If your status is irregular, get advice on the immigration side before filing — but do not simply write the money off.
• Missing the fund’s short windows— 1 year to complain, 6 months from the confirmation — while waiting to see if the employer’s promises ripen.

Start by writing down two dates — your last day of work, and the oldest unpaid payday — and gathering the records while you still have them. Every deadline above counts from those.
