Reported Cases:
Significant Representations; Acted as lead trial counsel for the defendants in Adams et al. v. Pinole Point Steel Company et al. (No. C-92-1962MHP, N.D.Cal. September 26, 2012). The Federal District Court for the Northern District of California's Judge Marilyn Hall Patel rendered a defense judgment with a 66-page opinion for a group of steel companies in a race harassment class action certified by the court over 15 years ago. The court noted that the class certification was probably unwarranted based on the trial record and the class counsel did not appeal the judgment. Represented an employer in a noncompetition trial in California Superior Court under Cal. B&P Code 17200 et seq. Represented employers in multiple unfair labor practice hearings before the National Labor Relations Board. Represented a sole-source community provider of health care by analyzing its work force and recommending work force restructuring to modernize its employment architecture and respond to the new PPACA legislation. This resulted in extensive collective bargaining over nurse, technical and service and maintenance workers and representation in all ensuring unfair labor practice litigation and arbitration. The employer was able to implement needed work force changes. Represented a leading provider of on-board entertainment for a cruise and event company in a wage and hour class action in California, which included allegations of failure to pay overtime and expense reimbursement violations. Represented a blood dialysis center in connection with unfair labor practices charges before the NLRB brought by UFCW Local 262 of New Jersey. Charges arose out of its attempt to become the exclusive collective bargaining representative of licensed practical nurses, registered nurses and other employees. The union alleged that the employer violated federal labor laws by terminating two and threatening other employees. Termination-related charges were dismissed and the union withdrew the remaining charges. Represented the Pension Benefit Guaranty Corporation in a class action alleging breach of fiduciary duty under ERISA. Won summary judgment on the pleadings that a plaintiff could not bring that type of action under Title I of ERISA. The above representations were handled by Mr. Birenbaum prior to his joining Greenberg Traurig, LLP.
