Recognizing the extraordinary economic struggles that confront working people, Darin vigorously advocates for workers and their unions.

Representative Work:

  • Glacier Northwest v. Teamsters Local 174, 598 U.S. __ (2023): As counsel of record, defended the right to strike before the U.S. Supreme Court. Maintained the existing framework for federal labor preemption (Garmon preemption): state claims challenging conduct even arguably protected by federal labor law remain subject to the Labor Board’s sole jurisdiction. And maintained broad protections for striking by limiting the exception to the objective test under longstanding law (strikers lose their protections when they fail to take reasonable precautions to avoid foreseeable imminent and aggravated harm to employer property from a sudden work stoppage); a super-majority of the Court rebuffed the employer’s efforts to broaden the exception to include all strikes where workers intend to harm the employer or its property.
