It's okay.
There is no overtime pay or compensatory leave for working on holidays. The company is small and very cost-conscious. Many things depend heavily on the boss's mood, and when faced with certain unreasonable demands, the boss may even tell you that things are even more unreasonable elsewhere, pressuring you to find a way to handle them. Be prepared to be on call at any time before joining.

Only the boss leads; there is no compliance with the Labor Standards Act, no fuel allowance, no meal allowance, no annual leave, and no overtime pay. Attendance at activities on holidays is not counted as paid work. The salary is only 25K, reduced to 24K after labor and health insurance deductions. The company is small and not competitive.
