If an employee is terminated in error or the termination date is incorrect, then you can either update the Termination Details on the employee record or remove them entirely. When you remove or change the Termination, the updated details will be included in the next STP Pay Event or Update Event that includes the employee.
Depending on the situation you will also need to consider any Transactions, including Terminations, that were entered for the employee and if they need to be reversed or amended. Below are some articles that may assist if you need to do this:
If the error was that the termination date was too early, then you have the option to remove the Termination Details and process an additional Termination Transaction with the correct Termination Date. When you do this you will need to amend the termination components to reduce them by what has already been paid. You should also review the tax values.
To remove or amend the Termination Details:
You can only select Resignation, Retirement, Dismissal or Casual Termination as the Termination Reason in an employee record. If you need to select any other reason, remove the Termination Details and enter a Termination Transaction. You can zero out any component that you don't need to pay as part of the transaction.
Go to Payroll, Maintenance, Employees, Employees.
Edit the employee you need to amend.
Select Termination Details.
Update the required Termination details or untick Termination Date to remove them.
Click OK to save the changes.
