Leave may stop accruing because the Employee's pro-rata hours have reached the Entitlement: Maximum each Period before their anniversary. The Entitlement: Maximum each Period on the leave class specifies the maximum accrual for employees within the entitlement period. If this is the case, their pro-rata hours will equal the maximum entitlement, and they won't accrue leave until they roll into the next entitlement period.
Leave can reach the maximums early, because the Employee was attached to:
New leave code but the leave balances weren't updated.
New contract hours and the leave balances weren't updated.
Contract hours leave class and no contract hours were specified. Leave will not accrue in these circumstances.
Additional hours were added to their pro-rata hours via a leave adjustment.
For more information, see:
When changing leave code - Change an employee's employment type from Casual to Permanent
When changing contract hours - Reduce an Employee’s Contract Hours so that Leave Accruals will remain correct
Additionally, Sick Leave and User Defined Leave can have a Maximum Accrual or Maximum Total Accrual. This is the maximum balance (Entitlement + Pro Rata - Taken) an employee can have. Once this is reached, they won't accrue leave until they are under the maximum accrual.
To check:
Go to Payroll, Maintenance, Employees, Employees.
Edit the Employee.
Select Leave.
Highlight the Leave that has stopped accruing and take note of the Prorata and Total Entitlement Hours.
Then go to Payroll, Maintenance, Leave and select the Leave Type.
Edit the Leave Code the Employee is attached to.
Review the Entitlement: Maximum per Period.
If the Employee's Prorata is equal to the Entitlement: Maximum per Period, this is the reason the Leave has stopped accruing.
If it's the Prorata and the Leave Type is Sick Leave or User Defined Leave, review the Maximum Accrual or Maximum Total Accrual.
If the Employee's Total Entitlement is equal to the Maximum Accrual or Maximum Total Accrual, this is the reason the Leave has stopped accruing.
