Sami, a production supervisor, first went to Fadia, the purchasing manager, who had already volunteered to transfer, to discuss with her the possibility of becoming her inventory control supervisor at the new facility. Fadia told Sami that Rana, the current inventory control supervisor, would not be transferring and that she would consider his request.
