What you need to know
You may need to ask for a cheque to be cancelled if you have been paid by cheque and it hasn't arrived at your unit.
What you need to do
You need to speak to your Unit HR Admin who can submit a request to SSCL to have the cheque revoked. You will need to tell your HR Unit Admin whether you want the cheque to be re-issued or paid into your bank account (you will need to provide bank details).
