In my area, the only thing we EVER get on Saturdays is 2nd and 3rd class mail. Flyers and junk mail. As long as the P.O. is still open for a few hours on Sat. I wouldn't even notice it. This one change shouldn't cost many jobs if any at all by itself. It's always been a mandated thing that they've never been able to get Congress to move on. The other cuts / changes will hurt for sure. If they would just enhance the tracking mechanism for priority, and just improve performance, they would give the rest some real heartburn.
