William P. Flanagan

"His vast knowledge of law in the employment field is amazing. He is fantastic and very helpful."

Chambers 2015

For more than 25 years, Bill Flanagan has worked side-by-side with clients, from start-ups to global businesses, on their most difficult employee and workplace challenges. He advises them on legal compliance and works with them to develop best practices and strategies to avoid litigation.

When disputes arise, he helps them achieve success in complex litigation, from individual cases to class actions, before federal and state courts and governmental agencies in the mid-Atlantic region and nationally. His cases range from individual claims to class and collective actions involving thousands of employees.

Bill works with management on all types of employment disputes, including those under federal and local anti-discrimination, employee leave, whistleblower, wage payment, and other employment statutes. He has extensive experience representing clients on corporate raids, trade secrets, and non-competition matters, and he litigates cases seeking emergency injunctive relief to protect client confidential information. Much of Bill's work has been for major companies and institutions in the energy, defense and government services, education, real estate, financial institutions, and life sciences sectors.

Bill also regularly advises clients on business restructuring programs (whether voluntary buyouts or reductions-in-force), and on all employment-related aspects of corporate transactions, including negotiating deal terms, leading diligence efforts, and negotiating and drafting the full spectrum of executive employment, compensation, and severance agreements.

Bill's practice extends beyond the United States. He works with colleagues from offices throughout the world on projects involving employee mobility, secondments, data transfer, and the development of cross-border policies, practices, and procedures.
