USPS tells workers to protect the sanctity of the mail, again "The US Postal Service told employees they have a responsibility to protect the sanctity of the mail. “When people send and receive mail through USPS, they trust that their mail will be treated with respect,” the organization told its workforce. “Damaging, delaying, tampering with or destroying mailpieces of any kind violates the sanctity of the mail and erodes the public’s trust in the Postal Service."
