What is a postal worker?

A postal worker works for the U.S. post office, and their skills and responsibilities depend on their specific role. As a postal service clerk, job duties include selling stamps and mailing supplies, registering or insure lettering or packages, renting out mailboxes, processing mail, and answering customer questions about postal services. As a mail carrier, job duties include delivering mail to businesses and homes along an assigned route, and collecting and sorting mail from those postal customers.
