Michael Weiner joined the firm in 2005, and became a shareholder in 2010.

Mr. Weiner’s practice focuses on providing legal representation to labor unions and to the trustees of Taft-Hartley multiemployer pension, health and welfare, and other employee benefit plans. He regularly appears in federal and state court, before the National Labor Relations Board, and in arbitration, and advises clients on all aspects of labor, employment, and employee benefits law.

His focuses include arbitrating contract interpretation and discipline cases and representing the institutional interests of unions, both counseling clients on legal compliance and defending them in litigation. Mr. Weiner also frequently represents unions in collective bargaining, serving as both an adviser and as lead negotiator for unions in a wide array of industries, including entertainment, health care, construction, and manufacturing.

In addition, Mr. Weiner has extensive employee benefits experience. He often handles plan design matters for multiemployer plans – drafting trust agreements, collective bargaining agreement language, plan documents, and summary plan descriptions – as well as submitting plans to the IRS for approval. He has litigated various types of employee benefits issues, including fiduciary issues, withdrawal liability, and collections matters. He also regularly assists plan trustees in navigating their investment responsibilities, ensuring legal compliance and negotiating terms with investment managers.

Matters handled by Mr. Weiner in recent years include successfully concluding several complex labor negotiations, winning an NLRB proceeding and related arbitration that resulted in the recovery of nearly $47 million by hundreds of union members, obtaining summary judgment for a union in a suit by a former employee, obtaining summary judgment for a multiemployer pension plan in a multi-million dollar suit brought by a former tenant and successfully defending that judgment on appeal, defeating a major retail employer’s suit to vacate an arbitration award that increased wages for thousands of employees, and winning an arbitration resulting in millions of dollars in backpay for hundreds of employees and successfully defending that decision in both the U.S. Court of Appeals for the Ninth Circuit and the United States Supreme Court.

Mr. Weiner is a member of the Employee Benefits Committee of the ABA’s Section of Labor and Employment Law and a contributing author of Employee Benefits Law, the leading treatise on the subject. He is also a member of the AFL-CIO Lawyers Coordinating Committee and the Labor and Employment Law Sections of the California Lawyers Association and the Los Angeles County Bar Association.

He graduated from UCLA (cum laude) and UCLA School of Law (Order of the Coif), where he was Articles Editor of the UCLA Law Review. His article on the NLRB’s remedial authority is frequently cited by academics and practitioners.
