César F. Rosado Marzán

Professor of Law
Claire Ferguson Carlson Fellow in Law

Professor Rosado Marzán currently teaches contracts, employment discrimination law, low-wage workers, and international and comparative labor and employment law. In past years he has also taught labor law and employment law.

Trained both as a sociologist (Ph.D. Princeton University) and attorney (J.D. University of Pennsylvania) Professor Rosado Marzán’s scholarship is doctrinal and socio-legal. Doctrinally, it has focused on U.S., comparative, and international labor and employment law. Socio-legally, he has studied labor inspectorates, labor courts, works councils, labor unions, and worker centers. His most recent doctrinal book, Principled Labor Law: U.S. Labor Law from a Latin American Method (Oxford 2019) won the Simón Bolivar Prize for Best Juridical Work from the Bar Association of Puerto Rico. His current socio-legal book project, tentatively titled Fox and Lion: Alt Labor, Norms, and Workers Rights in the 21st Century, explores how worker centers help to promote social and legal norms that expand workers’ rights in the United States despite being small and underfunded groups. He is also coauthor in the upcoming 4th edition of the casebook Labor Law in the Contemporary Workplace: Cases and Materials (West). Additionally, he is writing an article on sectoral bargaining in Uruguay and another one on how economic coordination operates in U.S. cities.

Originally from Puerto Rico, Professor Rosado Marzán is a proud member of the Bar Association of Puerto Rico (Colegio de Abogados y Abogadas de Puerto Rico). He is also an active member of the Law and Society Association, the Labor Law Group, the American Sociological Association, among other professional groups.

Prior to coming to Iowa Law, Professor Rosado Marzán taught at IIT Chicago-Kent College of Law, where he also was Co-director of the Institute for Law of the Workplace. He has been a visiting faculty member or scholar at the Universidad Autónoma de Madrid School of Law, Stockholm University's Law Department, the American Bar Foundation, and the Oñati Institute for the Sociology of Law. Before becoming a professor, he worked in New York City law firms representing labor unions and employees.

Professor Rosado Marzán currently lives in Iowa City with his wife, two sons, two dogs, and cat.
