Indefinite-Term Contract Workers in Korea: Meaning, Rights & Differences from Regular Employment

What Is an Indefinite-Term Contract Worker?

The term "indefinite-term contract worker" (무기계약직) is not an official designation found in statute. It is widely used in practice and in the media to refer to workers who have concluded an employment contract without a fixed term but are treated as a separate employment category from regular (정규직) employees. In plain terms, think of it as "an employee who has no worry about contract expiry, but receives different treatment from regular employees."

Automatic Conversion After 2 Years on a Fixed-Term Contract

The most common path to indefinite-term contract status is automatic conversion from a fixed-term contract. Article 4 of the Act on the Protection of Fixed-Term and Part-Time Workers (기간제 및 단시간근로자 보호 등에 관한 법률; hereinafter the Fixed-Term Act) provides that if an employer uses a fixed-term worker for more than 2 years, the contract is deemed — without any separate agreement — to have been concluded without a fixed term.

In other words, even if the written contract says "contract worker," once 2 years have passed the worker is legally in an indefinite-term status. However, if one of the exceptions listed in Article 4(1) of the Fixed-Term Act applies — such as workers aged 55 or older, professionals holding a doctoral degree, or holders of the highest-level qualifications — the worker may remain on a fixed-term contract beyond 2 years.

How Does This Differ from Regular Employment?

Legally, indefinite-term contract workers enjoy the same protection against dismissal without just cause as regular employees, under Article 23 of the Labor Standards Act (근로기준법 제23조). This means an employer cannot unilaterally terminate the worker on the grounds that a contract period has ended.

In practice, however, differences in pay structure, promotion paths, and welfare benefits compared to regular employees are common. This has led to criticism that such workers are "indefinite-term in name only." Article 8 of the Fixed-Term Act prohibits discriminatory treatment without reasonable grounds, and workers who experience discrimination may file a discrimination correction application (차별시정 신청) with the Labor Relations Commission.

Note for foreign workers: Your employment contract may set terms above the statutory minimum, but it cannot fall below the protections described here.

Indefinite-Term Contract Workers in Public Institutions

Public institutions and local governments frequently convert fixed-term workers to indefinite-term contract status in accordance with government guidelines. In such cases, workers typically go through a "conversion review" (무기계약직 전환 심사) and are placed into a separate employment category. Even after conversion, a separate pay scale from that of regular (general-track) employees is often applied, and the resulting gap in treatment for workers performing the same duties continues to be a widely raised concern.

Severance Pay and Annual Leave

Indefinite-term contract workers are subject to the same severance pay (퇴직금) and annual leave (연차유급휴가) rules as other workers. If you have worked continuously for 1 year or more and averaged at least 15 hours per week, you are entitled to severance pay, which must be paid within 14 days of separation. If payment is delayed, late-payment interest of 20% per year accrues under Article 17 of the Enforcement Decree of the Labor Standards Act (근로기준법 시행령 제17조). For annual leave, workers with less than 1 year of service accrue 1 day per month (up to 11 days), and workers with 1 year or more are entitled to a base of 15 days.
