The Agency HRL must process the separation action in SAP using PA40 - Personnel Action and selecting Separation and Action Reason.
Once the separation is processed, please notify Core HR and provide a copy of the resignation notification and Separation Form. If the employee is not available or unwilling to sign the form, that must be indicated on the Separation Form. Upon receipt, Core HR will review and process it accordingly.
Detailed instructions on processing Employee Separations can be found online here.
