After selecting the "Staff" tab in the Settings page, select the "View Staff" tab.

You may remove an employee simply by clicking on the "Delete" button next to the employee's name in the list. Once you click on the button, a confirmation window will appear. Click on "Yes" if you really want to delete the selected employee. If the employee has upcoming appointments remaining in his or her schedule, a warning window will appear indicating that the employee has future appointments set: you will not be able to remove the employee until his or her appointments are updated or cancelled.
