There is no Constitutional right to collective bargaining. If there is the federal government is actually violating it by denying those rights to federal employees.
Sure there is.
It the same right that allows corporations to lobby the government.
You really are ignorant of the Constitution aren't ya?
Not as much as you, which is not a very high standard.
Why don't federal employees have collective bargaining rights?
Erm..probably because of some unconstitutional unitary executive power wrangling?
What's your point?
