The NLRA provides employees with certain rights to join together to improve their wages and working conditions, with or without a union. The NLRA essentially limits how employers may react to employees who form or join labor unions, conduct collective bargaining, or take part in strikes and other forms of concerted activity. The NLRA created the NLRB and empowered it to administer and enforce the Act.
