Adam R. Rosenthal represents a broad spectrum of employers in all areas of employment law before federal and state courts, and the American Arbitration Association and JAMS. He has significant trial and arbitration experience in single plaintiff and class action cases involving:

  • Wage and hour disputes such as allegations of missed meal and rest breaks, unpaid overtime, off-the-clock work and time shaving
  • Wrongful termination
  • Sexual harassment and disability discrimination
  • Defamation
  • Misclassification of manager "exempt" employees
  • Non-compete agreements and trade secrets

Among his notable successes, Adam co-chaired a two-week trial in which he obtained a complete defense verdict on allegations of disability discrimination, retaliation, and violation of the California Family Rights Act. In a week-long single plaintiff arbitration involving race discrimination and retaliation, he not only obtained a complete defense verdict, his client was also awarded a portion of the attorney’s fees. He has successfully defeated multiple motions for class certification which claimed violations of the California Labor Code and the Fair Labor Standards Act. On several occasions, Adam has settled class action lawsuits with the plaintiff in exchange for a dismissal of the entire lawsuit, resulting in considerable savings for Adam’s clients. 

In addition to his trial and arbitration practice, Adam advises clients on:

  • Implementing arbitration policies
  • Employment policies and procedures
  • Compliance issues
  • Litigation avoidance
  • Employee benefits and compensation
  • Trade secrets

Adam regularly delivers presentations on recent developments in employment law and sexual harassment avoidance to human resource professionals and managers. He represents a wide range of companies and industries:

  • Multinational retailers and restaurant chains
  • Biotechnology
  • Professional services
  • Internet retailers
  • Online gaming
  • Education
  • Assisted living facilities
  • Nonprofit organizations

Before joining Littler, Adam was an associate at another San Diego law firm. In law school, he served as the sole student member of the University of California's Board of Regents, working on a number of high-profile matters. Prior to law school, Adam taught English and history at a middle school in Oakland, California, as a member of Teach For America.
