These special agents are not bargaining unit ~ rather, their job is the direct application of federal policy.
Excluding USPS, the overwhelming majority of federal employees are non-union. In, USPS, almost everyone is union. The military are non-union.
I think that should give you all the information you need to see why no union representative was present at the firing in the parking lot ~ on the other hand the Regime's agents imagine they need a safer place than their own offices to fire one of their whistle blowers.
I can attribute that only to a fear of being gunned down by their own co-workers and maybe their bosses!
All is not well in ATF.
Thanks. What a sad state of affairs, when you have to worry more about your safety because of your co-workers, than the criminals you pursue. Management at that place has be rampant with corruption, and promotions must be based on whoever your daddy is.
