29 U.S.C. § 157 — Right of employees as to organization, collective bargaining, etc.

Employees have the right to organize themselves, and to form, join, or help labor organizations. They can bargain together, through people they choose to represent them, with employers. They can also join with each other for the purpose of collective bargaining or other mutual help or protection. Employees also have the opposite right: they can refuse to do any or all of these things. But this right to refuse has one limit — it does not apply if a lawful agreement, allowed under section 158(a)(3) of this title, requires union membership as a condition of the job.
