The USPS News is reporting that post office employees should be aware of the potential security threat of someone posing as a postal employee. They are concerned that a potential terrorist could gain easy access to both sensitive governmental and private offices by simply wearing a mail carrier's uniform.

Managers have been instructed tell employees who are leaving the postal service to remove all identifying USPS insignia, emblems and patches from their uniforms. Employees are also supposed to turn their uniforms in to their local postmasters/supervisors if they leave USPS or change employment categories that require different uniforms.
