Semiconductor, battery, and software engineering talent runs deeper here than anywhere in Asia outside Japan, and 71% of adults aged 25 to 34 hold a tertiary degree, the highest share in the OECD. Most EOR providers put a Korean hire on payroll in five to ten business days once the contract and Four Major Insurance enrolment clear, though an E-7 work visa adds four to eight weeks for Certificate of Eligibility processing.
The cost most foreign employers miss is severance, which accrues at 30 days of average wage per year of service from month twelve and adds roughly 8.3% on top of a statutory contribution load that already runs 10.7% to 12.0%.
This calculator adds the employer share of the Four Major Insurances to gross salary: National Pension at 4.75%, health and long-term care at 4.07%, Employment Insurance from 1.15%, and Industrial Accident Insurance from 0.7%. The National Pension ceiling of KRW 6,590,000 in monthly salary caps the employer contribution at KRW 313,025 and flattens the cost curve for senior hires, and the optional EOR fee field shows the per-employee service charge alongside that statutory total.
Statutory employer contributions add 10.7% to 12.0% on top of gross salary, with the spread driven by headcount band and industry risk class rather than salary level. Severance accrual adds a further 8.33% and is shown separately below, since it is a retirement benefit obligation rather than a social insurance contribution.
The economy grew 1.0% in 2025, its slowest full year since 2020, with exports carrying most of the load while construction contracted. Headline unemployment stays near record lows, but that number hides a labour market splitting in two: health and social welfare added 173,000 jobs in the year to July 2026 while manufacturing shed 68,000 for a 25th consecutive month.
Most foreign employers assume 30 days of notice buys them a clean exit, which is not how Korean dismissal law works. The second surprise is severance, which accrues from month twelve on average wage rather than base salary.
Labor Standards Act Article 23 bars dismissal without just cause at any workplace regularly employing five or more people. Courts read the standard narrowly: serious misconduct, or documented performance failure after a completed improvement plan. Redundancy on its own does not clear the bar.
Article 26 notice, 30 days in advance or 30 days of ordinary wage in lieu, is a separate obligation. Paying it does not make an unjustified dismissal lawful. Remedies at the Labor Relations Commission are reinstatement plus back pay to the dismissal date.
Under the Employee Retirement Benefit Security Act, anyone with 12 months of continuous service at 15 or more hours per week is owed 30 days of average wage for each year served. Average wage means total pay across the final three months, including regular allowances and a pro-rated share of the previous 12 months of bonus.
Budget on base salary alone and the figure lands short. Payment falls due within 14 days of the last working day, accrues 20% annual interest after that, and non-payment carries up to three years imprisonment under Article 44.
Forty regular hours plus a maximum of 12 overtime hours per week. Overtime pays a 50% premium, night work between 10pm and 6am pays a further 50%, and holiday work beyond eight hours pays double.
Flexible scheduling shifts when hours are counted but the ceilings hold: 140 overtime hours per quarter, 250 per six months, 440 per year. Managers and executives sit outside the cap, which is where most misclassification of supposedly exempt staff happens.
Much of the LSA, including just cause dismissal, written termination notice, overtime premiums, and statutory annual leave, applies only where five or more employees are regularly employed. Companies placing one or two people in Korea sometimes assume they sit below it.
The threshold counts the legal employer's workforce, not your headcount. An EOR is already well past five, so every provision applies from day one. Legislation extending the LSA to smaller workplaces is under review, which would close the same gap for direct entities.
The Protection of Fixed-Term and Part-Time Workers Act caps aggregate fixed-term employment at two years. Past that point the relationship is treated as indefinite automatically, with no renewal decision required, and the just cause standard now governs any exit.
Renewal patterns matter before the deadline too. Repeated renewals can build a legitimate expectation of continuation, and Korean courts have treated non-renewal in those circumstances as a dismissal needing just cause. Track the 24-month clock per person, including any earlier period the same worker spent on a contractor agreement doing the same job.
Tertiary attainment among 25 to 34 year olds is 71%, the highest in the OECD, and manufacturing has shed jobs for 25 consecutive months, which has loosened a market that was tight two years ago. The practical constraint is not supply but the 24-month fixed-term ceiling, which forces a permanence decision earlier than most foreign employers plan for.
Samsung, SK Hynix, LG, and Hyundai have trained several generations of hardware and process engineers, and the recent manufacturing contraction has put experienced people back on the market. Health and social welfare added 173,000 jobs in the year to July 2026 while manufacturing lost 68,000 and construction 57,000. Software talent is deep but competes against domestic platforms with strong compensation and brand pull.
English is workable in Seoul finance, consulting, and multinational roles, but engineering and operations teams default to Korean and business English varies sharply by function and age band. Employment contracts should be issued in Korean, with a bilingual version if your legal team needs one. Assume Korean-language capability is required for anyone managing local staff or dealing with the labour office.
Past 24 months the contract converts to indefinite automatically, at which point the just cause standard applies to any exit. Korean employment counsel routinely advise starting people on one-year fixed terms precisely to preserve a clean non-renewal option. Decide before month 24 whether you want this person permanently, because after that the decision is made for you.
Pangyo Techno Valley in Seongnam is the main software and gaming cluster, Suwon anchors Samsung's semiconductor and device workforce, and Ulsan is heavy automotive and shipbuilding. Daejeon carries public research institutes and KAIST spinouts. Remote arrangements are accepted in tech but far less common in manufacturing and finance.
It is owed on resignation as well as dismissal, and people track the accrual, so a mid-tenure hire will often ask how the retirement pension plan is structured. Annual bonuses and meal or transport allowances are expected as part of the package rather than extras. Year-end tax settlement is a familiar January ritual that employees expect their employer to run properly.
Teams that place senior hardware and platform engineering in South Korea generally build their volume delivery, regional support, and European coverage elsewhere, and these four are where that second hire tends to land.
