The 1935 Wagner Act was flawed in what way?

1935, the labor policy of the American government changed overnight from one that broke unions to one that supports them. The US government's new promotion was designed to boost productivity and reduce the conflict between employers and workers. The Wagner Act encouraged collective bargaining. It represented a distinctly American way for dealing with conflict. The Wagner Act represented the reality of the new industrial change on the ground. It was an attempt to channel that social movement and activity into a system that would respect workers rights, but also preserve the basic fundamental tenets of capitalism. It was meant to reform, not revolutionize. The Wagner Act envisioned the recovery of the American economy through the workers bargaining powers. Legalized labor unions via government certification, required employers to accept unions and engage in "good faith bargaining," National Labor Relations Board to oversee process via petition/cards and secret ballot elections, defined Unfair labor practices, and empowered NLRP to see court injunctions and fines against employers. Fundamentally re-wrote relationships. Unprecedented years of rights and potential economic power, but at the same time there were significant limits to these revolutionary laws. Women, agricultural, and domestic workers were left out.
