The Texas Department of Criminal Justice supervises Parole Officers in the State of Texas.  You brother's Parole Officer does indeed have a "boss." The problem here is that I do not know what the guidelines are for a Parole Officer and what they are expected to do within the framework of their position.  Verifying employment may be something that they need to do. Although they should not do anything intentional to have him lose his job they surely can not withhold information that would help perpetrate a fraud on some level.  I am not sure that the "don't ask don't tell" mantra works here.  I would seek help from an attorney in your area.  Good luck.
