Leave & Attendance
Part of Leave and absence systems
Checking how a system handles different work patterns
A leave system that assumes everyone works five equal days can misstate time off for a rostered or part-time employee.
A leave system built for five equal days can misstate time off for a rostered or part-time employee. Use these checks with payroll: enter the employee’s work pattern, calculate the expected result independently, then compare the system’s balance and export. A pass matches the applicable entitlement rules; an unexplained difference is a fail.
First check the rules against the Fair Work Act 2009, the National Employment Standards (NES), and any applicable modern award or enterprise agreement. Use Fair Work Ombudsman guidance and seek advice on casual and part-time arrangements. Software configuration does not determine an employee’s entitlement.
Check 1 — full-time baseline. Full-time and part-time annual leave accrues progressively based on ordinary hours. Full-time employees accrue 10 days of paid personal/carer’s leave per year; part-time entitlements are pro-rata based on ordinary hours.
Check 2 — part-time employee with unequal days. Enter the ordinary hours for each day and test a partial-day absence on a scheduled workday. Compare the deduction with payroll’s independently calculated result; the balance should not treat days of different lengths as equivalent.
Check 3 — changing daily hours. Test a move from five short days to four long days, or between full-time and part-time. A balance held in hours should remain a valid measure through the change; if the system displays days, check that it converts the hours rather than treating an old day as equal to a new one.
Check 4 — shift worker with a changing roster. Test a leave period that crosses a public holiday and compare the deduction and resulting balance with payroll’s calculation under the applicable rules. Annual leave is typically at least four weeks per year; certain shift workers may receive five weeks, so check the applicable entitlement rather than assuming every shift worker is treated alike.
Check 5 — roster change after approval. Identify which schedule the system used, then check that any correction is recorded and the resulting balance matches payroll’s calculation for the applicable work pattern.
Reject a demonstration that shows only a standard full-time employee if that is not representative of the workforce. Ask to see the request and resulting balance for each relevant pattern.
If a result requires a manual calculation, record the calculation, its reviewer and the evidence retained. This keeps a flexible process from becoming an invisible spreadsheet.
How Work Patterns Affect Leave Accrual and Deduction
- Part-time employee (unequal days)Leave deducted based on actual ordinary hours per day; not treated as equivalent days
- Shift worker with changing rosterLeave balance must convert hours accurately across schedule changes; public holidays affect deductions
- Changing from part-time to full-timeAccrual rate updates based on new ordinary hours; balance should reflect change in hours, not days
Key Checks for Leave System Accuracy
- Check 2: Part-time unequal daysTest partial-day absence; ensure deduction matches pro-rata hours worked
- Check 3: Changing daily hoursBalance should hold in hours, not days; verify correct conversion during shift changes
- Check 5: Roster change after approvalConfirm system uses correct schedule and balance is recalculated accurately
