I think the PO will still be open, it's just carrier service that they plan to eliminate.
Saturday definitely seems like the most logical choice. Like you said, most business offices are closed on Saturday. It doesn't seem fair to cut those businesses off from mail service on Tuesday.
My last job was at a talent agency in LA, and the mail was incredibly important to us. All of the actors' checks came through the mail, and we would sit waiting for the mailman hoping there would be money (kinda needed it to pay the bills). We would to take our commission from the checks, then race to forward the money to the actors, who wanted it yesterday. I was constantly running to the mailbox trying to catch the day's pickup. For a business like that, eliminating service for a day would be devastating.
It seems that they're thinking too much about the private sector, rather than the impact this will have on businesses. If they kill service on Tuesday, a lot of businesses will start using FedEx and courier services, and the PO will lose more money. Stoo-pid.
