Freedom of Speech, freedom of assembly, freedom of petition, right not to be discriminated against, etc etc.
1. Your right to negotiate contracts
2. Your right to be protected from corporate power graps, like when they want to lower your wage in favor of higher profits to keep for the executives, or if they want to lay you off in favor of higher profits
Do you want anymore
LOL - Are you kidding me?
Freedom of speech, the only group that legally can not violate your freedom of speech is the government. You have NO right to freedom of speech at a job. NONE
Freedom of Petition - Same thing
Discrimination - LOL Legally companies can't discriminate and those laws are enforced by the government, not unions.
You have no right to negotiate contracts. You don't have to sign a contract PERIOD
You have no right to be protected from "corporate power grabs"
Sure , list more it just exposes your ignorance of your rights.
