On a 15,000 baht salary, what is overtime per hour?

At 8 hours a day the hourly wage is 15,000 ÷ (30 × 8) = 62.50 baht, so working-day overtime is at least 1.5× = 93.75 baht an hour.

Why divide by 30 instead of the actual working days?

Section 68 of the Labour Protection Act defines the hourly wage of a monthly-paid employee as the monthly wage divided by 30 times the average working hours per day.

How much is holiday work paid?

If you are already paid for that holiday (e.g. monthly staff), at least 1× extra; if not (e.g. a daily worker on the weekly holiday), at least 2×. Overtime on a holiday is at least 3×.
