About Marcos Rodriguez Holguin

Marcos Holguin is an Attorney at SR Holguin, PC. In that capacity he represents unions at every stage and in all aspects of labor and employment law matters.

Marcos was raised in a family of many generations of union members that instilled in him the importance of the labor movement. In just his immediate family, Marcos’ father is an honorary member of the International Longshore and Warehouse Union (ILWU), Local 13; his mother is a retired member of the University Professional and Technical Employees (UPTE), Local 2; his paternal grandfather was a member of the International Brotherhood of Teamsters (IBT), Local 208; his paternal grandmother was a member of the United Teachers Los Angeles (UTLA); and his maternal grandfather was a member and elected officer of the United Automobile Workers (UAW), Local 216.

While in college, Marcos served as a Law Clerk at the union-side labor and employment law firm that would become SR Holguin, PC. During law school, he gained litigation experience as a member of his law school’s National Trial Team. Marcos also served as a Law Clerk and later as a Post-Bar Law Clerk at the Los Angeles County District Attorney’s Office, Major Crimes Division. While there, he assisted in the prosecution of some of Los Angeles County’s most complex and high-profile cases.

At SR Holguin, PC, Marcos serves as a Litigator, an outside General Counsel to unions, a Counselor to union officers, a Collective Bargainer, a Trainer to union officers and stewards, and an Advisor with respect to political, policy, legislative and regulatory affairs.

Marcos is experienced representing unions in state and federal court and before administrative agencies including the National Labor Relations Board (NLRB) and Equal Employment Opportunity Commission (EEOC). Marcos is also experienced representing unions in elections, collective bargaining, grievances, arbitrations, discipline proceedings, internal governance, and all day-to-day operations. Further, Marcos uses his specialized education and political expertise to represent unions before elected and appointed officials and in public affairs. He also represents and advises unions’ political action committees (PACs) regarding campaign finance law and all aspects of administration.

In 2020, Marcos was selected as part of an exclusive group of young union-side litigators from across the country to participate in the AFL-CIO Union Lawyers Alliance’s rigorous Litigation Workshop.

When not representing unions, Marcos can often be found spending time with his dog, or at LA Dodgers baseball or UCLA Bruins football games.
