I believe the Annual Leave displayed in iTrent Self Service is incorrect
In the first instance please refer to the Annual Leave Calculator on this page to confirm what your leave entitlement should be.
Please be aware that iTrent includes Bank Holidays and University Closure Days in your annual leave allowance (both booked and taken). You can view a list of UK bank holidays for England on the gov.uk website.
Your entitlement can also include up to five days carry-over of any unused leave from the previous year.
