Maybe add several "Day off work/school" options instead of the singular. Suggestions:
- Major Holiday - Most sims celebrate this Holiday - Unpaid day off, doesn't use PTO allowance. If you have the day off anyway you get a day in lieu (unpaid day off whenever you want it).
- Minor Holiday - Some sims celebrate this Holiday/Easy to fit around work - Optional day off work (pop-up similar to during events asking if you want to take PTO/UTO), uses PTO/UTO allowance if you take the day off.
- National Day - Sims observe traditions on this day, but business continues as normal - You need to book PTO/UTO in advance if you want this day off.
This would require adding UTO (unpaid time off) but this could be useful for other things too (bereavement leave etc).
