The operation process of our company is that the transfer-out department sends a transfer email to the transfer-in department, and sends a copy to the head of the personnel department and the transfer-in department at headquarters. The e-mail needs to indicate the transfer-out date and the salary settlement date of the transfer-in department, and then let the employees fill in the relevant transfer materials after the transfer, bring the personnel files to the transfer-in department, and the transfer-in department is responsible for keeping the files.
