There's nothing stopping you from going outside the agency to complain. Every government agency, be it the county DMV or the U.S. Congress, has internal complaint services and auditing practices.

The motive behind this is to stop every internal dispute from ending up in federal court every time it comes up, not to stifle free speech. I see the merit in that, but I think it raises potential problems.
