The US Postal Service is a quasi government agency.

Wages, health care and pensions are not subsidized by US taxpayers. It is all funded by revenues received from postage and merchandise sales.

As a matter of fact, Congress requires the Postal Service to PreFund Retiree benefits 75 years out. Is there ANY business that could survice this mandate?

Instead of blaming government workers for perceived problems, why don't you just blame Congress & the President?
