Workplace Action for a Growing Economy Act or the WAGE Act This bill amends the National Labor Relations Act (NLRA) to require the National Labor Relations Board (NLRB) to award back pay and additional damages to any employee whose rights under the NLRA have been violated by an employer; impose penalties upon an employer for failing to post a notice of the rights of their employees under the NLRA; impose penalties upon an employer whose violations of the NLRA result in the discharge of an employee or other serious economic harm to the employee; provide civil remedies, including restraining orders, and a private right of action for violations of the NLRA; require the NLRB to issue an order requiring collective bargaining when a majority of valid ballots have been cast in favor of union representation; prevent the classification of employees as supervisors for the purpose of denying such employees the protections of the NLRA; and expedite the establishment of initial collection bargaining agreements. The bill empowers the NLRB to enforce its own orders without petitioning a court for enforcement.
