Wow, that one statement speaks volumes. About the controllers not being the most of the Air Traffic Employees. Why would there not be more controllers than support staff? Does it really take more support staff to keep the controllers procedures and equipment in order?
As to one union to cover more than just one. Take a look at NATCA.net and see how we look as a combination union. We don't have everyone in the agency, but we do cover quite a few of the specialties...
