Mr. Zonn focuses on all aspects of labor and employee relations law representing management. He has extensive experience in the investigation and litigation of all forms of employment discrimination claims before local, state and federal agencies and state and federal courts, involving a wide variety of employers ranging from the airline industry to education. He has also litigated employment at will claims. Mr. Zonn frequently represents employers before the National Labor Relations Board in representation proceedings, unfair labor practice cases, and handles collective bargaining negotiations and arbitrations. Additionally, he has been involved in wage/hour investigations with the United States Department of Labor, along with unemployment compensation matters.

In an effort to minimize the risk of potential litigation, Mr. Zonn also spends considerable time counseling clients on general labor relations and equal opportunity advice including reductions in force, disciplinary matters, maintenance of union free status, development of personnel policies and employee handbooks, affirmative action plans, and wage and salary planning. He has also negotiated and prepared separation and severance agreements designed to insulate employers from future litigation.

Mr. Zonn has conducted training for clients focusing on practical responses to employment issues in the workplace, including sexual harassment, effective hiring practices and maintenance of union free status.
