Unpaid wages vanish if you wait and grow if you know — how ₩9M piled up ₩1.73M in a single year

You leave a company after three months without your ₩3M monthly wage. ₩9M. The owner keeps saying it is coming and holds out for a year. How much did you lose in that year? The law adds interest to it, at 20% a year. ₩1.73M has piled up on top of the principal, several times what a bank deposit pays. And since October 2025 a new article has been added: wages deliberately withheld can be claimed in court at up to 3 times. Unpaid wages are money that vanishes for those who wait, and a claim that grows for those who know.

The first step is the 14-day clock. Article 36 of the Labor Standards Act: when a worker leaves or dies, the employer must pay wages, compensation and every other amount owed within 14 days of that day. That means severance, pay for unused annual leave and promised bonuses as well as wages. 'We will pay on the next payday' does not match the law. There is one proviso: with special circumstances the deadline may be extended by agreement between the parties, and that agreement requires the worker's consent. Answering 'all right' to 'please wait a little' can be treated as an extension agreement, so even if you wait, put in writing how much will be paid by when. During employment a separate clock under Article 43 runs: wages must be paid in full, directly, at least once a month on a fixed date, so payday itself is the legal deadline.

The exceptions are fixed. While the company is in rehabilitation or bankruptcy proceedings, or where it is appropriate to have a court decide whether the wages are owed at all, interest is paused. And one practical point: this interest does not arrive computed on its own. Whether in a complaint or a lawsuit, you must state that you claim late-payment interest together with the principal. Write only the principal and you receive only the principal.

Third step: what if the owner truly has no money? The Wage Claim Guarantee Act answers. The state pays the unpaid wages in the employer's place and then recovers them from the employer. It is called the substitute payment, in two kinds. First, the insolvency substitute payment: when the company enters rehabilitation or bankruptcy or is recognized as unable to pay, the state pays the last 6 months of wages and the last 3 years of severance (raised from 3 months by amendment, for rehabilitation or bankruptcy decisions or inability findings made on or after 20 August 2026), with a monthly cap set by notice between ₩2.2M and ₩3.5M depending on age at leaving. Second, the simplified substitute payment: even if the company has not failed, a court judgment or a certificate of unpaid wages issued by the labor office is enough. The cap is ₩7M for wages and ₩7M for severance. There are deadlines: a leaver must file the labor office complaint within 1 year, or the lawsuit within 2 years, of the day after leaving. And a current employee who meets the income threshold can also receive it once per workplace for the most recent 3 months of wages. The certificate is the key: file a complaint with the labor office, and once the investigation confirms the arrears, the document is issued and you can apply for the simplified substitute payment without a lawsuit.

The fourth step is three numbers. First, 3 years: a wage claim not exercised for 3 years is extinguished by limitation, and the time you spent waiting counts. The period runs separately from each payday for that month's wages, and a labor office complaint alone does not stop it. That takes a court claim such as a lawsuit or payment order. Second, criminal penalties: violating the 14-day settlement or regular payment carries up to 3 years in prison or a fine of up to ₩30M. Not paying the interest itself carries no criminal penalty. And it cannot be prosecuted against the worker's wishes, so the owner wants a settlement and tries to cut the principal as its price. Declining prosecution is the worker's card, not an obligation, and an employer whose name has been published who violates again during the publication period is an exception and is punished even after a settlement. Third, 3 times: the newly created Article 43-8. Where non-payment was clearly deliberate, wages were unpaid for 3 or more months in a year, or the total is 3 months of ordinary wages or more, the worker may claim up to 3 times the unpaid wages in court. Severance is left out of the treble amount. The court weighs the duration and circumstances, the employer's efforts, interest already paid and assets, so the full 3 times is not automatic. Even so, the price of holding out no longer ends at principal plus interest. The treble claim too reaches only arrears arising on or after the 23 October 2025 commencement.

The checklist. First, gather evidence: the employment contract, pay slips, attendance records, and texts and conversations with the owner. A verbal promise is evidence once recorded. Second, count: list unpaid wages, severance and leave pay item by item, and compute late-payment interest from the day after the legal deadline. Third, file a complaint with the Ministry of Employment and Labor. It is accepted online, a labor inspector investigates and issues a correction order, and if arrears are confirmed the certificate is issued. Fourth, apply for the simplified substitute payment with the certificate (a leaver must have filed the complaint within 1 year of the day after leaving). Amounts within the cap are received here first. Fifth, the remainder, the interest and, for deliberate non-payment, treble damages go through the courts; for small sums there are simplified procedures such as a payment order.

The core of the order is one thing: the 3-year limitation and the clock keep running while you wait. Someone who gathers evidence in the first month of arrears and someone who moves after six months of patience get different outcomes under the same law. Nationality is irrelevant. Foreign workers get the same law and the same substitute payment.

Two things to do now. First, if wages are owed to you, gather the evidence today and calculate principal and interest. The next step starts once the number is in hand. Second, if you have already waited a long time, count the days left before the 3-year limitation. The effect of an extension agreement, the details of certificate issuance and the requirements for treble damages differ case by case, so if the amount is large or the company digs in, move with a labor attorney or lawyer. Unpaid wages are your claim, whatever the owner's circumstances. The law attaches interest to that claim and has even built a road for the state to pay in the owner's place.
