How to prevent the leakage of customer information in the delivery of finished goods in warehouse?

Sign a business confidentiality agreement, and make it clear that customer information belongs to the business secrets of the enterprise, and the disclosure needs to bear the responsibility. There is no other good way. You can't hide customer information from the delivery staff. Delivery men are human beings, too. They may leak. Theoretically, it is impossible to control the process, and it can only improve the professional ethics of distribution personnel. You can pay 100 more every month, and then deduct 100. 200 yuan (the specific amount depends on the company) is paid to employees every month as confidential money of trade secrets 1 year after leaving the company. If it is not leaked within one year, it will be unconditionally distributed to employees and written into the signed business confidentiality agreement. But it should also be clear that the company may be held accountable for other responsibilities.
