This situation applies if an employee has just walked out the door and there is no money to be paid out or you just want to remove a name from the employee list.
Access the Employee List from the main Window, by clicking on the 'Employees' button.

At the Employee List, double click on the employee you wish to terminate. This takes you into the first set of tabs of employee information. Down the bottom hand left, click on the 'More' button.

This takes you to the extra set of tabs of employee information. Go to the 'Termination 4' tab.

The essential task here is to enter in a date in the termination date field, but you can also fill out the other fields if you desire. For an explanation of these fields see Termination TAB
Click on 'OK' to return to the previous set of tabs, and then click on 'OK' to return to the Employee List, and you will see this employee is no longer 'Active' i.e. below the list, if you only have a cross next to the 'Active' box, this employee will not show up. You would have to put a cross next to the 'Terminated' box for the employee to appear in the list above.
In summary, the act of placing a date in the 'Termination Date' field of an employee's Termination 4 tab and then clicking on 'OK' will terminate them.
If the termination date is in a previous financial year then the employee will not appear even on the 'Terminated' list of employees. If you wish to view this employee's details you will have to temporarily change the financial year in the Taxation Details 8 tab accessed by the Company picture button. Don't forget to change the financial year back when finished with the terminated employee.
