The Wagner stands as a moment in American history where people saw the working class take control.
The Wagner Act of 1935 was one of the largest movements seen for the purpose of benefiting labor unions. With nearly 3 million people involved in labor unions vs the 5 million who were members 10 years prior. The Wagner Act, also known as the National Labor Relations Act of 1935 was formed to protect the rights of people who were in labor unions: protecting the rights of striking, engaging in collective bargaining (negotiation of wages with employers), and to protest against working conditions.
These unions were established with the purposed of unifying people of the working class; to fight for better wages, working conditions, hours, and benefits. Jim Casey was in a union on strike during his jail sentence because the owner wasn't paying the prisoners what he said he would and cut the pay by nearly 4 cent an hour down to either 1 and a half or 2 cent an hour; not even enough to sustain themselves and save up their money.
