For those that previously worked for the Texas A&M University System and had a UIN created in the UIN System, that UIN is used in the directory. For new Compass Group employees that never worked for The Texas A&M University System, an alpha-numeric value is used for the UIN. If the CompassGroupUSAemployeeID is six digits, this value is set to '00' + CompassGroupUSAemployeeID + 'C', e.g. '00123456C'. If the CompassGroupUSAemployeeID is seven digits, this value is set to '0' + CompassGroupUSAemployeeID + 'C', e.g. '01234567C'.
