Overtime Pay: How Extra Hours Pay 1.5x
Just like a mobile carrier charges a higher penalty rate once you exceed your monthly data limit, overtime pay adds at least a 50% bonus on top of your normal hourly rate for working past standard hours.
Definition Overtime pay is the mandatory extra compensation workers receive for clocking hours beyond standard legal limits (typically 8 hours a day or 40 hours a week). By law, employers must pay at least 1.5 times the regular hourly rate (a 50% premium) for every extra hour worked.
Past the Standard Hours, Your Time Is Worth 1.5x
When you burn through the 10 gigabytes included in your phone plan, every extra gigabyte comes with a premium surcharge. Labor laws treat your working hours on the exact same principle. Standard labor regulations set statutory working hours at 8 hours a day and 40 hours a week.
The moment you cross that boundary, it counts as overtime. For instance, if an employee earning $10 (10,000 KRW) per hour works 9 hours in a single day, that extra hour must be paid at $15 (15,000 KRW), not $10. By law, employers must add a 50% premium on top of the regular ordinary wage.
Overtime does not just mean staying late at the office on a weekday. If you have already logged 40 hours Monday through Friday and come in for 4 hours on Saturday, all 4 of those Saturday hours count as overtime as well.
What Happens When Overtime, Late Nights, and Weekends Overlap?
Overtime pay is calculated from your 'ordinary wage'—the base hourly rate derived from your fixed, regular pay. Multiplying this base rate by 1.5 gives your standard overtime hourly rate.
Calculations change when overtime stretches past 10 PM into the night. Work between 10 PM and 6 AM qualifies as 'night work,' which triggers its own separate 50% surcharge. When overtime overlaps with night work, you earn double your base wage (100% base + 50% overtime + 50% night premium) for those hours.
The same stacking rule applies when working over 8 hours on weekends or public holidays. Holiday pay and overtime pay are calculated separately and added together.
A Closer Look: Not Every Workplace Works the Same
Why does the law mandate such a steep 1.5x wage penalty? The goal is to discourage companies from habitually overworking staff and to protect workers' health and right to rest. The true aim is safeguarding life after work rather than simply handing out extra cash.
However, the 50% premium does not automatically apply to every business. Under South Korea's Labor Standards Act, the mandatory 50% overtime surcharge applies only to workplaces with 5 or more regular employees. Businesses with fewer than 5 workers can legally pay just the standard 100% base hourly wage for overtime hours.
In addition, many contracts use a 'blanket wage system' where overtime pay is already bundled into a fixed monthly salary. This often sparks debate because employees may work extensive extra hours without receiving any additional compensation beyond their fixed pay.
🤔 Common misconceptions
Working overtime guarantees a 1.5x pay rate at any company regardless of size.
The mandatory 50% overtime premium applies only to businesses with 5 or more regular employees. Workplaces with fewer than 5 workers are legally allowed to pay just the standard 100% base hourly wage for overtime.
