Forgive my somewhat predictable and in-character response, but if the instructors and staff have a salary grievance with the FAA, it seems to me they should either join the ATC union or organize their own union, and then deal with the FAA collectively.

It further seems to me that public entreaties to Congressmen to raise the salaries of any particular class of Federal employees are not very likely to succeed. The elected Representatives are bound to realize that the letters they received will (mostly) have been solicited by the employees concerned, and will then place the appeal in the same category of similar requests from all other Federal employees, who, like all other hourly and salaried employees, believe their pay should be higher.
