Compensatory Leave & Holiday Substitution
What is compensatory leave?
- Requires a written agreement with the employee representative
- Grant leave for the hours that reflect the premium rate
- Set the usage deadline and unused-leave settlement in advance
Adopting compensatory leave does not remove the burden the company carries. What changes is the form and timing of that burden. Cash that would have gone out stays on the books as a liability of 'leave time,' and that liability disappears only when employees actually take time off. So if you use compensatory leave only to prevent peak-season cash outflow, leave piles up in the off-season or unused balances end up settled in cash, and the spending is merely pushed back. Another easy misconception concerns total working hours. Granting compensatory leave does not erase overtime already worked, so it has no effect on the calculation of the 52-hour weekly limit.
The two systems have different requirements. Compensatory leave must be converted with the premium rate included. If an employee worked 8 hours of overtime, you must grant 12 hours of leave, not 8, for it to substitute for the pay. Hours where night and overtime work overlap carry stacked premiums, so the conversion multiplier goes even higher. Holiday substitution, by contrast, turns that day into a regular working day in the first place, so no premium arises at all. However, to move a public holiday to another day you need a written agreement with the employee representative, and for the weekly paid holiday, the administrative interpretation requires a basis in the rules of employment or individual consent, plus sufficient advance notice. Labor Day cannot be substituted; if someone worked that day, it must be handled with pay or compensatory leave.
The most common problem in the field is the belief that 'we gave a substitute day off, so it’s settled.' If an employee who worked 8 hours on a holiday was given a day off the following week with no written agreement and no advance substitution procedure, the company has still not paid the 0.5x premium. This shortfall accumulates over three years and gets claimed all at once in a complaint or at a departing employee’s final settlement. Treating unused compensatory leave as 'expired once the deadline passes' is the same mistake. Because it substitutes for wages, whatever wasn’t used must be paid out, and it must always be settled upon resignation or retirement.

Holiday substitution follows separate requirements and procedures.
Consider a hypothetical case. Company A, which makes side dishes and ready meals in the Seoul metropolitan area, has 240 employees, and in the eight weeks before Chuseok (Korean Thanksgiving) its orders double. Overtime and holiday pay for its 130 production workers in September–October runs close to KRW 200 million (≈ US$149,600) every year. Last year, Saturday workers were given a weekday off instead, with no extra pay. A former employee filed a complaint, and the company had to pay KRW 14 million (≈ US$10,500) retroactively.
- At the labor-management council in the first week of August, the HR director explained, 'This year, for 8 hours of special work we’ll credit 12 hours of leave, and anything unused by December 31 will be added to your January pay,' and then signed a written agreement with the employee representative.
- The labor-affairs manager set up conversion formulas in the attendance system — 1.5x for overtime and 2.0x for overlapping night hours — and changed the payslips so each person’s accrued balance appears at the bottom every month as 'Compensatory leave remaining: 00 hours.'
- When the Production Team 2 squad leader pushed back, saying 'If people leave, the line stops. How can anyone take time off?', the plant manager set up a rotating leave schedule of 2 people per squad for two months starting in November and set aside a separate KRW 9 million (≈ US$6,730) budget for day-labor replacement staff.
- For the October 3 (National Foundation Day) work during the Chuseok holiday, the company decided to handle it as holiday substitution rather than compensatory leave. It designated October 11 as the substitute day and collected a notice and individual consent forms two weeks in advance.
- After it was pointed out that work on May 1 (Labor Day) cannot be replaced with time off, the company removed it from compensatory leave and paid it as holiday work pay instead.
- As a result, allowance payments for September–October fell from KRW 196 million (≈ US$146,600) to KRW 112 million (≈ US$83,800), and 2,760 of the 3,180 accrued compensatory leave hours (87%) were used within the year, so the unused-leave settlement came to just KRW 5.2 million (≈ US$3,890).
