39 CFR 268.1 - General principles.
In order to conduct its business, the Postal Service has the need to collect various types of personally identifiable information about its customers, employees and other individuals. Information of this nature has been entrusted to the Postal Service, and employees handling it have a legal and ethical obligation to hold it in confidence and to actively protect it from uses other than those compatible with the purpose for which the information was collected. This obligation is legally imposed by the Privacy Act of 1974, which places specific requirements upon all Federal agencies, including the Postal Service, and their employees. In implementation of these requirements, the following rules of conduct apply:
(a) Except as specifically authorized in § 266.4(b)(2) of this chapter, no employee shall disclose, directly or indirectly, the contents of any record about another individual to any person or organization. Managers are to provide guidance in this regard to all employees who must handle such information.
(b) No employee will maintain a secret system of records about individuals. All records systems containing personally identifiable information about individuals must be reported to the Manager, Records Office.
(c) All employees shall adhere strictly to the procedures established by the U.S. Postal Service to ensure the confidentiality and integrity of information about individuals that is collected, maintained and used for official Postal Service business. Employees shall be held responsible for any violation of these procedures.
