You must be on something if you believe federal unions are open and above board...they are the corruptest of the corrupt. They should not exist they are communist to the bone!!!
The biggest group of federal unions represent postal workers and include a supervisors' association and a postmasters' association. APWU and NALC simply have not been known for anything outside of your normal AFL-CIO sort of union process.
They don't have the right to strike and haven't.
