  • Collective Bargaining Agreement Did Not Waive Employees' Right to Strike Against Employer's Unfair Labor Practices

    Date:
    February 17, 2012

    In Mastro Plastics Corp. v. NLRB, 350 U.S. 270 (U.S. 1956), the Supreme Court addressed two issues: (1) whether the collective bargaining agreement at issue, in which the union agreed "to refrain from engaging in any strike or work stoppage" during the agreement's term, waived the employees' right to strike solely against their employer's unfair labor practices; and (2) whether Section 8(d) of the National Labor Relations Act (NLRA) deprives individuals of their employee status if, during the statutory 60-day waiting period, they strike against their employer's unfair labor practices.
