Areas of Practice
Arthur N. Four represents private and public-sector labor unions and organizations in arbitration proceedings, before administrative agencies and in litigation before state and federal courts, and provides advice and counsel to unions on collective bargaining, internal union matters, and the scope of a union’s duty of representation in a wide range of industries and settings.
Professional History
Arthur joined SSDS as a partner in September 2026, continuing his practice of traditional labor law begun in 2018 at Reich, Adell & Cvitan, another Los Angeles union-side labor law firm.
In his career, Arthur has advocated for and won victories on behalf of unions and union members in countless labor arbitrations, before administrative agencies such as the National Labor Relations Board, California Office of Administrative Hearings, California Public Employment Relations Board, and US Department of Labor, and in litigation in state and federal court in matters involving the National Labor Relations Act, Labor Management Reporting and Disclosures Act, California Education Code, California Labor Code, and numerous other laws, regulations, and statutes affecting labor organizations and working people.
In addition to his traditional labor law experience, Arthur has also spent significant time litigating on behalf of individual union members and California employees in employment, wage and hour, employee benefit, and other Union-adjacent legal matters.
Arthur’s decision to become a union-side attorney followed that of his father, Michael D. Four, a partner at SSDS for nearly 40-years. Due to the same strong influence, Arthur remains a devoted member of the small but proud labor lawyer–Deadhead community.
