Two records of leave — the register and the payroll sheet — will eventually disagree, and the reconciliation will land on whoever is least able to refuse it. One record, feeding both, is the whole fix.
Decide what happens at the edges
- How accrual works for a mid-year joiner
- What carries over at year end, and what lapses
- How unpaid leave reaches payroll as a deduction
- Who can approve leave that takes a balance negative
These four answers are what a leave policy actually is. Once they are configured, balances stop being a monthly negotiation.
