About Unfair Labor Practice Claims

Unfair labor practice claims involve violations of the National Labor Relations Act, which protects employees' rights to organize, join unions, and engage in collective bargaining. These claims may address employer interference with union activities, discrimination against union members, or refusal to bargain in good faith with a certified union representative.
