Reports :: Floating Holidays That Are Not Available Every Year

I have a Floating Holiday that doesn't happen every year how do I incorporate this in Access 2010, I have a report that calculates Paid Time Off for employees and when they have a year that has a Floating Holiday or doesn't have a floating holiday, how do I incorporate that into a query or report without losing the calculations from the previous year reports.

for example, this year a floating holiday is allowed so my calculations work, but next year if a floating holiday isn't allowed how do I make it a 0 without losing this years data.

I tried tblFLOATINGHOLIDAY with several years listed (at first used Yes/No) and a field that you either put 8 or 0 (8 hours or 0 hours). Then I used a query combining tblEMPLOYEES and tblFLOATINGHOLIDAY with citeria for FLOATINGHOLIDAY to be 2015 so all the records would show 8 under FLOATING HOLIDAY. But it comes up with no records.
