The post office brass could start out by closing on Tuesdays, and using that day for postmaster training and paperwork. The amount of new requirements heaped upon postmasters, most of which have NO impact on customer service, are mind-boggling.
Close all small rural post offices that have no rural delivery routes. More radical solutions would include starting to “grandfather” out rural routes upon retirement of carriers. Most rural customers come to town once a week or more. Let them pick their mail up at their PO box.
Another huge savings would be eliminating delivery of regular at the door in urban areas and older suburbs. Move mailboxes to the curb in all neighborhoods.
re: Close all small rural post offices that have no rural delivery routes
Having lived in such an area for most of my youth I would suggest an alternative to closing them, and leaving the residents without access to the postal system. Lease a space just big enough to accommodate the mail coming in and going out. Staff each one with one person who does everything, including the janitorial duties. Then impose a reasonable surcharge on mail handled by the facility to cover some of its costs.
