Great question. Since you posed this question in this fashion, I will answer it via the federal requirements that each employee agrees to at the start of their appointment (whether temporary or permanent):39 U.S. Code u00a7 1011 - Oath of officeThis u201cRIGHTu201d that you mention in your question is not a u201cRIGHTu201d.Rather it is a matter of DUTY as required by the Federal Appointment. This is a voluntary obligation by anyone who signs up for employment with the United States Postal Service. They can willingly resign if they do not (or no longer) agree to the DUTY to uphold the United States Postal Service Domestic Delivery Manuel, the Employee Labor Relations Manual or the M-39/M41 (City Delivery Carriers Duties and Responsibilities).As for YOUR mailbox, you are required to pickup your mail. As noted in part via Section 242.6 of the M-41 (City Delivery Carriers Duties and Responsibilities) and USPS DMM 507 Mailer Service Section 1.1d - Mail Unclaimed, mail is considered unclaimed when the addressee has either abandoned the mail or has failed to call (collect) the mail from the mailbox.As I was told in training in response to the question of how many times should a customer pick up their mail from their box: u201cUSPS Delivers every day except Sunday. A customer should pick up their mail every day that USPS deliversu201d.Put your name and any other names that currently receive mail on a tag and place that tag in the mailbox. Pickup your mail everyday its delivered.
