Employees leave can be adjusted through the Opening Balances fields on an Employee Profile.
Calculate how many extra leave hours the employee has accrued, for example:
Adding 24 hours of Annual Leave
Navigate to Menu > Settings > Employees > click the Edit button for the effect employee
In the Employee Profile go to the Opening Balances area:
A negative adjustment can also be entered, for example: i.e. "-36"
Then Navigate to a recent unlocked payslip for the adjusted employee.
Click Recalc Leave button located on the top of the employee's payslip.
This will now update the employee's balance with the adjusted leave.
