Are Postal Workers for the USPS veterans?

some might be. axe one.

If you mean are they all hired only if they served in the military, no. It gives a preference, but is NOT mandatory for being hired. if you mean does it give you veteran status to use V.A. resources, no. That is reserved for those who served in the military services only.

Some, not all

Sure.
Because every single postal worker has exactly the same opinion on every single issue on earth.

******* retard.
