Editing Norris–La Guardia Act (section)

== Overview ==
The Act states that [[yellow-dog contract]]s, where workers agree as a condition of employment not to join a [[trade union|labor union]], are unenforceable in federal court. It also establishes that employees are free to form unions without employer interference and prevents the [[United States federal courts|federal courts]] from issuing [[injunctions]] in nonviolent labor disputes. The three provisions include protecting worker's self-organization and liberty or "collective bargaining", removing jurisdiction from federal courts vis-a-vis the issuance of injunctions in non-violent labor disputes, and outlawing the "yellow-dog" contract.

Section 13A of the act was fully applied by the [[Supreme Court of the United States]] with a 1938 decision, ''[[New Negro Alliance v. Sanitary Grocery Co.]]'', in an opinion authored by [[Associate Justice of the Supreme Court of the United States|Justice]] [[Owen Roberts]]. The Court held that the act meant to prohibit employers from proscribing the peaceful dissemination of information concerning the ''terms and conditions of employment'' by those involved in an active labor dispute, even when such dissemination occurs on an employer's private property.
