Through the passages of the 1935 National Labor Relations Act.
The National Labor Relations Act (NLRA) was enacted by Congress in 1935 to defend the rights of both employees and employers, to promote collective bargaining, and to reduce some private sector labor and management methods, which were harmful to the general prosperity of workers, businesses and the U.S. economy.
The main way in which the Second New Deal created a way for workers to exercise their rights in the workplace is by making it easier for unions to form--unions which allowed workers to exercise "collective bargaining rights" that increased the likelihood of higher wages.
