The math on that one isn't working for me, unless I'm not understanding you correctly. They should be staffed high enough to allow everyone that has PTO time take Christmas off?
Why should it matter what day of the year? If you have time off, you should be able to ask for it off and for coverage to be fine. Still doesn't mean you need a policy for a abusers. Start with a policy that rewards employees for showing up at work on the traditional holidays.
@PhilosopherPilot : at my company, you are in violation of sick policy if you call in sick for a spouse or child's illness to take care of them. You can take personal days, unpaid, if there is staffing.
