An accurate leave question is easier to answer than “Why is my balance wrong?” A short evidence pack helps both you and the employer identify where the numbers diverge.
Gather the source documents
Collect the holiday clause, later amendments, applicable policy, annual balance notices and approved or rejected requests. Add your normal working days for each relevant period.
Build a one-page chronology
List employment start date, leave-year boundaries, schedule changes, longer periods of incapacity, parental leave and any notice date. Only include facts relevant to the balance.
Ask for a calculation, not a conclusion
Request a breakdown showing opening entitlement, pro-rata adjustment, days taken, days carried in and any days treated as expired. Ask which rule supports each adjustment.
Keep the exchange neutral and in writing. If the answer reveals a formal deadline, termination issue or unresolved legal interpretation, obtain qualified advice without delay.
