Certain posts and roles are not able to be used together as per the DfE so the staff member's contract will need to be amended.
If you are unsure on this please liaise with your Local Authority or the DfE.
If you wish to amend the role or post please go to Admin > Personnel > Staff - find the staff member and click onto the black cog next to any contracts in scope. Amend the data and update at the bottom to save.
