What Weinberg, Roger & Rosenfeld does

Weinberg, Roger & Rosenfeld is a union-side labor law firm headquartered in Emeryville, California, founded in 1974 and organized as a professional corporation. The firm provides comprehensive legal representation to labor unions, Taft-Hartley employee benefit plans, and individual workers across private and public sector labor relations. Core practice areas include collective bargaining, grievance arbitration, unfair labor practice proceedings before the NLRB and PERB, ERISA compliance and trust fund administration, wage-and-hour class actions, employment discrimination litigation, workplace immigration matters, appellate advocacy, and union governance. The firm operates four offices across Emeryville (principal office), Los Angeles, Sacramento, and Las Vegas, serving clients primarily in California, Nevada, and Hawaii.

The firm's service model is professional services-based, with revenue generated through attorney billing on litigation, arbitration, advisory, and transactional matters. There is no proprietary technology platform; service delivery relies on experienced attorneys (roughly 25-30 named legal professionals) supported by paralegal and administrative staff. The firm handles approximately 1,000 arbitration files annually and has represented unions in thousands of jury and bench trials, hundreds of reported appellate decisions, and proceedings before the U.S. Supreme Court, federal circuit courts, the California Supreme Court, and numerous administrative agencies. Distribution is direct through attorney-client relationships, with new client acquisition driven by industry reputation, referrals within the labor movement, conference participation, and the firm's WRR Labor Law Updates newsletter.

Founded on principles of social, economic, and racial justice, the firm maintains an ideological alignment with the labor movement that serves as both mission and market positioning. The firm pioneered union-side public sector representation in California, with founder Stewart Weinberg serving as attorney of record in the first decision of the California Public Employment Relations Board. The current shareholder group includes specialists in ERISA/benefits, public works/prevailing wage, class actions, immigration, and arbitration practice management, reflecting an integrated platform that supports clients across the full lifecycle of union activity from organizing through contract enforcement and benefit plan administration.
