Unions are the only voice and power of the working class, corporations do not want workers to have or know their rights.
corporations have many levels of legal representation but seek to deny any representation to workers and destroy unions in the process. unions are the right of the working class, no union's = low wages ,discriminating employer's and loss of rights.
Why is this important?
right to work agenda of the political right means right to work for lower wages to the working class.
