The move is intended to save the Postal Service up to $2 billion annually, the Associated Press reports. Under the plan, letters will still be delivered to postal boxes but not to residences or businesses. Post offices that are currently open on Saturdays will continue to be open.
While letters will be delayed, packages will still be delivered on Saturday. Package delivery for the USPS has increased 14% since 2010 and has not suffered from the drop that letters have, mostly thanks to email and other messaging systems.
It’s uncertain whether the USPS will be able to implement the plan without an act of Congress. While it’s an independent agency and doesn’t accept tax dollars, it’s under congressional oversight. And Congress has halted earlier moves to eliminate Saturday delivery.
