The Post Office needs to go under a huge restructuring if it is going to make it another 12 months if that. Couple of things that would help...
1) No Saturday delivery. Who wants to get a bill on Saturday anyway?
2) Consolidation. I know in my town there are three Post Offices within 15 minutes of each other. That's unnecessary. Keep the most convenient location.
3) Union contract renegotiation. 80 % of expenses for the USPS are LABOR. Are you serious? Unions have prevented the USPS from keeping up with changing market conditions. No surprise there. Unions hate progress.
