What makes up hourly pay

Base pay (hours × wage), weekly holiday pay for 15+ contract hours (Art. 55), and — at workplaces with 5+ employees — statutory premiums (Art. 56): overtime beyond 8 h/day or 40 h/week +50%, night work 22:00–06:00 +50% (stacking with overtime), holiday work +50% up to 8 h and +100% beyond. The 2026 minimum wage is 10,320 KRW.

Example: convenience-store night shift

22:00–07:00 with a 1-hour night break, 5 days, 10,320 KRW: 8 h/day of which 7 h at night. Weekly: 412,800 base + 180,600 night premium + 82,560 holiday pay = 675,960 KRW, about 2,937,046 KRW/month. Under 5 employees: 495,360/week, about 2,152,339/month.

Deductions

2026 employee social insurance rates used: pension 4.75%, health 3.595%, long-term care 13.14% of the health premium, employment 0.9%. Workers under 60 contract hours/month are generally exempt from the first three. Income tax is not included.

FAQ

Do part-timers get overtime pay?

At workplaces with 5+ employees, yes: hours over 8/day or 40/week earn 50% extra (LSA Art. 56), and part-timers also earn 50% for hours beyond their contract hours (Fixed-term & Part-time Act Art. 6(3)).

What changes under 5 employees?

No statutory overtime, night or holiday premiums (Art. 11). Minimum wage and weekly holiday pay still apply.

Is 3.3% withholding correct for part-time work?

3.3% is for independent contractors. Most part-timers working set hours under direction are employees and should be on payroll with social insurance (if 60+ h/month).

Are breaks paid?

Breaks (30 min per 4 h, 1 h per 8 h) are unpaid, unless the worker must stay on call — then it counts as working time.
