Hello, this is Cheongchul Law Firm.

As year-end approaches, many Korean companies send emails asking employees to use up all remaining annual leave. But what if you cannot finish your leave because of heavy workload? Can the employer refuse to pay unused leave compensation? The short answer: an email alone does not eliminate the employer's duty to pay. Korean Labor Standards Act exempts that duty only when the employer follows the strict annual leave use promotion procedure.

1. What the Annual Leave Use Promotion System Is

Article 60 of the Korean Labor Standards Act grants 15 paid annual leave days to employees who worked at least 80 percent of the year. If the employee cannot use the leave within the statutory period, the employer must normally pay compensation equal to the wage for the unused days.

However, Article 61 provides an exception: when the employer takes certain steps to promote the use of annual leave and the employee still does not use it, the duty to pay can be waived. This is called the annual leave use promotion system. Its purpose is to ensure that employees actually take vacation, not to reduce the employer's burden.

2. Procedural Requirements under the Labor Standards Act

To benefit from the exemption, an employer must complete a two-step procedure.

First Notice: Six Months Before Expiration

Within 10 days starting six months before the leave period expires, the employer must notify each employee individually of their unused leave days in writing and ask the employee to designate the dates when the leave will be used.

Second Notice: Employer Designates the Dates

If the employee does not designate the dates within 10 days, the employer must, no later than two months before the expiration, designate the dates for the employee in writing.

Both notices must be in writing. Verbal announcements or general bulletin board notices generally do not meet the requirement.

3. The Supreme Court's Rule on Refusal of Labor Receipt

Completing the formal procedure is not enough. The Korean Supreme Court has held that even when both written notices are properly delivered, the promotion effect is denied if the employee shows up on the designated leave date and the employer fails to clearly refuse to receive their labor.

If the employer assigns work or simply tolerates the employee's presence, that day is treated as a regular working day, not annual leave. The employer therefore remains liable for the unused leave compensation.

4. Employee Rights When the Employer Fails to Comply

When the employer skips a step or fails to clearly refuse labor on the designated day, the employee retains the right to claim unused leave compensation. The statute of limitations is three years, the same as ordinary wage claims, so a claim can be made even after the employment ends.

In practice, many companies wrongly assume that a single email or bulletin board notice satisfies the law. The statute requires a written individual notice that specifies the unused days and the dates. Timing, method, and content all matter.

5. Key Practical Issues and How to Respond

Common issues in disputes include:

• Proof and timing of the written notice: if the employer cannot prove delivery, the procedure is treated as failed.

• Employer's reaction when the employee shows up: silent acceptance or work instructions defeat the promotion.

• Fiscal-year-based operation: when leave is tracked by fiscal year rather than hire date, procedural compliance becomes more demanding.

• Retiring employees: leave unused at retirement is also subject to a separate compensation claim.

Employees should keep all notices, attendance records, and work instructions. Employers should remember that the system aims to ensure leave is actually taken; formal compliance alone is not enough.
