Postal Service contractors frequently employ their own language.  For example, to a postal contractor, a “highway contract” is not a contract to build a road but rather a contract to transport mail on a road. A new example of this postal-only language is something called a “disagreement.”  This is the word used to describe what the rest of the government contract world would call a “protest.”  The Postal Service’s internal bid protest (“disagreement”) procedures have been around now for several years, but have recently been revised, so this would be a good time to review them.
