The Wagner Act, also known as the National Labor Relations Act of 1935, played a significant role in Black history by granting workers - including Black workers - the right to join unions and engage in collective bargaining. This legislation was a landmark victory for labor rights and provided important protections for workers against unfair labor practices by employers.

In the context of Black history, the Wagner Act was particularly important as it helped to empower Black workers who were often subjected to discrimination and mistreatment in the workplace. By allowing them to organize and negotiate with their employers, the Wagner Act helped to advance economic and social justice for Black workers by providing them with a platform to voice their concerns and improve their working conditions.

The Wagner Act was a key piece of New Deal legislation during the presidency of Franklin D. Roosevelt and helped to strengthen the labor movement in the United States. Its impact on Black workers and other marginalized groups cannot be overstated, as it paved the way for greater equality and protections in the workplace.
