As an employee, you are able to cancel a Leave Request that has not yet been approved or denied.
To do this, go to your Leave tab. Your pending requests are at the top of the page and have a 'Cancel Request' button.
When you click on this, you will be see a pop up box asking you to confirm you would like to cancel this request. Click 'OK' and your Admin/Manager will no longer have this request from you.
Please be aware once your leave request has been approved, only your Admin/Manager can delete it.
