Lisl Soto (née Duncan) is a shareholder in the Los Angeles office of Weinberg, Roger & Rosenfeld.

Ms. Soto represents Unions in all aspects of labor and employment law.  She handles arbitrations, contract negotiations, serves as general counsel to several multiemployer Trust Funds and Labor Management Cooperation Committees, and deals with California’s laws governing public sector employees.  Ms. Soto gives Union leaders trainings on many topics, including grievance processing, contract negotiations, wage and hour law, anti-harassment and discrimination, and forms of protected leave.

Ms. Soto with others at the firm represented employees in Marquez v. City of Long Beach (2019) 32 Cal.App.5th 552, successfully establishing new precedent in California over whether charter cities like the City of Long Beach are required to comply with state minimum wage laws.  The Court of Appeal ruled that while charter cities may govern themselves as to matters that are deemed municipal affairs, their authority is limited and must give way to state authority on important issues of statewide concern—in this case, providing California workers with a living wage.

Ms. Soto also regularly practices before the National Labor Relations Board in both representation matters and unfair labor practice proceedings, including in the case of Purple Communications, 361 NLRB No. 126 (Dec. 11, 2014) [overruled by the Trump-era Board in Caesars Entertainment d/b/a/ Rio All-Suites Hotel and Casino, 368 NLRB No. 143 (Dec. 17, 2019)].

Ms. Soto presents at legal conferences such as the 39th Annual Piper Lecture at Chicago-Kent College of Law, and with the AFL-CIO Union Lawyers Alliance (ULA) and Peggy Browning Fund.

Ms. Soto’s practice focuses extensively on wage and hour litigation.  She is experienced in all aspects of class action litigation, including assembly of classes, discovery covering large groups of similarly situated employees and motions for class certification.  Ms. Soto has acted as the primary plaintiffs’ attorney on numerous wage and hour class action lawsuits in the California counties of Alameda, Fresno, Kings, Los Angeles, Orange, San Diego, San Francisco, Santa Clara, Sacramento and Solano, as well as in federal court in the Central District.  A sampling of these matters include, Godfrey v. Oakland Port Services Corp. (AB Trucking) (Oct. 28, 2014) 220 Cal.App.4th 1267 (Alameda County); Herrera et al. v. Petrochem Insulation, Inc., Case No. 5:14-cv-02066-VAP (SPx) (Central District); Henninger et al. v. AECOM Technology Corporation, Case No. 11-C-0141 (Kings County); and Mataiumu et al. v. Cytec Engineered Materials, Inc., Case No. SA CV14-01548 DOC (RNBx) (Central District).

Prior to joining the firm, Ms. Soto received her undergraduate degree from the University of California at Berkeley majoring in English with a minor in Peace & Conflict Studies, and graduated from the University of California, Hastings College of the Law.  She worked as a Peggy Browning Fund Fellow in the Division of Judges at the National Labor Relations Board in 2007, and interned at the Equal Employment Opportunity Commission and with a small firm in Barcelona, Spain in 2006.  She served as Editor in Chief of the Hastings Race & Poverty Law Journal from 2007-2008.  During law school, Ms. Soto participated in the Workers’ Rights Clinic, Refugee & Human Rights Clinic, Pilipino American Law Society, and received Hastings’ 3L Class Leader Award in 2008 by vote of her peers.

Ms. Soto endeavors to dedicate her legal career to social justice and positively impacting the lives of working people.
