The NLRA prohibits certain acts, called “unfair labor practices,” by employers and by labor organizations. The NLRA requires that the board investigate charges and, where it finds a violation of the law, devise a remedy to redress the effects of the unlawful act. The NLRA is not a punitive statute, and does not provide for punishment of wrongdoers. However, the board’s remedial orders are enforceable in federal courts of appeals, and a violation of a court decree enforcing a board order may be punished by the court through a civil contempt proceeding.
