We are paid for all our overtime. Can we work more than 52 hours a week?

No. The hours cap and the pay obligation are separate regulations and satisfying one does not satisfy the other. An employee who works 55 hours and is paid the full premium on all 15 extended hours has been paid correctly and the employer has still breached the 12-hour extended work limit. The reverse also holds: 45 hours is inside the cap, and the 5 extended hours still attract the premium. Check compliance twice, once against the clock and once against the payslip.

Our workload is seasonal. Can we average 52 hours across the month?

Not under the ordinary working hours regime, where each week is assessed on its own — 60 hours followed by 44 is a breach in the first week regardless of the average. Averaging across a settlement period is possible under the flexible or selective working hour schemes, but those are statutory arrangements with conditions: the workplace rules or a written agreement with the employee representative, a defined settlement period, and daily and weekly ceilings. Rearranging a roster and calling it flexible working does not adopt one.

Is waiting time working time?

It can be, and this is where reported hours most often understate the real figure. Time spent on standby for work under the employer’s direction and supervision counts as working time even when no task is being performed. So an employer cannot designate pre-shift preparation, mandatory training or on-call waiting as break time simply by labelling it that way. The test is whether the employee was genuinely free to use the time, which is a question about the facts rather than about the timesheet.

My company has four employees. Does the 52-hour week apply?

The statutory working hours limits and the premium pay provisions apply principally at workplaces with five or more ordinary employees, so a four-person workplace should not be assumed to sit under the same structure. That is not a blanket exemption from labour law: minimum wage, the written employment contract and wage payment obligations apply irrespective of size. Headcount is the first checkpoint in any Korean employment question, because it decides which provisions are in play at all.

The 52-Hour Week in Korea, and What It Does Not Buy

The most expensive misunderstanding about Korean working hours is that the weekly cap and the overtime premium are the same regulation, so that paying one settles the other.

They are not. The Labor Standards Act limits how long you may be worked and separately requires what you must be paid, and the two are enforced through different mechanisms — one of which is criminal.

Two tests, run separately

Passing one says nothing about the other

55 hours, every premium paid in full. Paid correctly — and 3 hours over the extended work cap.

45 hours, inside the cap. Within the limit — and 5 hours of premium may be owing.

Compliant means both: the clock and the payslip, checked against each other.

Money does not buy hours, and hours do not discharge money.

This guide is the clock. The payslip is the afternoon's.

Before anything: headcount

The statutory working hours limits and the premium pay provisions apply principally at workplaces with five or more ordinary employees.

Below that, do not assume the same structure. What does not depend on size is a separate list — minimum wage, the written employment contract, the obligation to pay wages — so a small workplace is not outside labour law, it is inside a different part of it.

40 hours, 8 hours, and what counts as an hour

Article 50 caps working hours, excluding breaks, at 40 a week and 8 a day.

The definitional question comes first, though: working time is not only time spent performing tasks. Time spent waiting for work under the employer’s direction and supervision is working time.

A break is a break only if you can actually use it

Pre-shift preparation, mandatory training and on-call waiting cannot be converted into break time by labelling them that way on a roster. The test is whether the employee was genuinely free to use the period, or was under the employer's direction. Companies whose reported hours sit suspiciously close to a limit are often carrying the difference here.

52 is 40 plus 12

Article 53 permits extended work, by agreement, up to 12 hours a week.

statutory        40 h
extended     +   12 h
                ─────
weekly max       52 h

Those twelve hours are not paid at the ordinary rate. The overtime pay calculator applies the statutory premiums to a given wage and hours.

Agreement is a live requirement, not a formality discharged at signing. A contract clause saying the company may order overtime when necessary does not by itself authorise unlimited extended work, and it certainly does not displace the cap.

Each week stands on its own

Under the ordinary regime, 60 hours one week and 44 the next is not lawful because it averages 52. The first week is a breach when it happens.

Averaging across a period is possible — but only through the statutory flexible or selective working hour schemes, and those are arrangements with conditions attached:

Workplace rules or a written agreement with the employee representative, depending on the scheme.

A defined settlement period, over which the average is taken.

Daily and weekly ceilings that still apply inside it.

Changing a shift pattern and calling it flexible working adopts nothing. If your employer is averaging your hours, there is a document that says so, and you are entitled to know which scheme it is.

Special extended work is an authorisation, not a decision

Work beyond the cap on grounds of disaster, accident or other statutory special circumstances runs through a procedure: the statutory grounds, the employee’s consent, and the Minister’s authorisation or after-the-fact approval.

Business pressure is not a ground

A tight delivery date, a surge in orders, or being short-staffed are management problems. They do not, on their own, convert into the statutory exception — and an employer that treats them as one has not obtained anything, it has simply exceeded the cap.

The sanction is criminal

Breach of the working hours limits carries imprisonment of up to two years or a fine of up to ₩20,000,000, separately from any liability for unpaid premiums.

Which changes what the evidence is. Attendance records, building access logs, PC sessions, work messaging, email timestamps and the instructions actually given are all capable of establishing long hours — and they are largely the employer’s own systems.

The order to check in

ordinary headcount at the workplace
  → contractual working hours
  → hours actually worked
  → over 8 in a day?
  → over 40 in a week?
  → extended hours within 12?
  → is a flexible or selective scheme lawfully in place?
  → then, separately, the premiums

Everything after the last arrow — the 50% rates, how extended and night work stack, the two tiers of holiday work, and why a comprehensive wage clause does not remove any of it — is the subject of its own guide, because it is a different regulation with different failure modes.

The sentence to distrust in either direction is “we are within 52 hours, so there is nothing to pay” and its mirror, “we pay for the overtime, so the hours are fine.” Both halves have to be true at once.
