Leave-Use Guide for Office Workers

Are substitute holidays always a day off?

In 2026, Independence Movement Day, Buddha's Birthday, Liberation Day, and National Foundation Day all overlap with a weekend, so the following Monday is designated a substitute holiday. However, workplaces with fewer than 5 employees aren't subject to paid-holiday rules under the Labor Standards Act, so check your company's size first.

Can my company force me to use leave on specific dates?

In principle, leave is used whenever the worker wants. A company can only request a change in timing if it can prove significant disruption to business operations, and if it wants to designate a company-wide day off during a bridge holiday and substitute it with leave, it needs a written agreement with the worker representative.

Kaltoesa tip: Handling leave before you resign

If you're planning to change jobs or resign, decide first whether to use up your remaining leave before leaving (extends your service period, which can be favorable for severance pay) or settle it as leave allowance (better if you need cash right away).
