For each leave year (April - March) the number of bank holidays/closure days within that leave year is shown in the calculator. The pro-rata entitlement is calculated in hours where each full-time day is equivalent to 7.2 hours. The number of hours that you should have worked on the bank holiday/closure days is deducted from your entitlement.
If your working pattern means you have more bank holidays in your working pattern due to the days the bank holidays fall on, it's possible to have a negative entitlement, depending on your working pattern and how the bank holiday and closure days fall in a particular year. If you have a negative entitlement this means that you owe the University that number of hours shown, and this amount will be deducted from your total annual leave entitlement within HR Organiser.
