The Post Office is going broke, and Taxpayers will have to fund the Pensions that were gained when the workforce was bloated and over-staffed, AND, over-paid.
As in ALL Government-run/Regulated operations, staffing exceeds work, AND, they Unionize to get golden parachutes of selling sick-time, earned vacation time, and pad the pensions in the final 3-5 years with un-Godly over-time (using their Union Seniority to assure they are in a position to do so).
This is not some rinky dink corrupt county government bud.
