Ennis represents employers before state and federal courts and agencies involving such claims as sexual harassment, race, sex, age and disability discrimination, wrongful discharge, breaches of covenants not to compete; cases arising under the Fair Labor Standards Act and ERISA, and various types of injunction proceedings.

Peter’s practice includes counseling employers on such diverse personnel-related issues as compliance with discrimination laws, hiring, evaluating and discharging employees, drug and alcohol testing, developing record-keeping and personnel policies and employee handbooks, pay practices and employee benefits, negotiating and administering collective bargaining agreements, and health and safety issues.
