Prior to joining JAMS, Mr. Segall served as the Head of Litigation for JP Morgan Chase for the period from 2003-2010, where the Employment Litigation function reported to him. The cases for which he was responsible at JP Morgan ran the gamut of class action cases involving wage claims arising under the Fair Labor Standards Act and state law and of alleged wrongful classification of employees and alleged violations of ERISA in connection with certain provisions of JPMC’s retirement plans, claims of discrimination based on gender, race, age, religion, disability and sexual orientation, claims of sexual harassment, claims of retaliatory discharge, and claims of failure to pay incentive compensation or other stock-based compensation, claims involving the violation of restrictive covenants, the disclosure of trade secrets and other proprietary and confidential information, defamation claims, and the right to recover amounts paid or stock compensation awarded under various compensation plans. These cases were pending in both state and federal courts in the United States, in arbitration proceedings, and in other forums worldwide.

Mr. Segall was also responsible for many investigations of alleged employee misconduct and allegations of alleged wrongdoing raised under the Sarbanes-Oxley Act of 2002.

Mr. Segall was also responsible for the approval of settlements and the establishment of litigation reserves in all significant employment cases.
