On July 5, 1935, the National Labor Relations Act (NLRA or Wagner Act) was signed into law.
One of the clauses states:
Employees shall have the right to self-organization, to form, join, or assist labor organizations, to bargain collectively through representatives of their own choosing, and to engage in other concerted activities for the purpose of collective bargaining or other mutual aid and protection.
Secretary of Labor Frances Perkins, having personally witnessed workers jump to their death during the Triangle Shirtwaist Factory fire, played a major role in getting the legislation passed.
