Clients look to Millie Warner to guide them through a wide range of employment law and human resources issues they face as part of doing business. Millie helps her clients avoid liability by consulting on disciplinary processes, termination of employees, and day-to-day human resources matters, and by drafting employment agreements, separation agreements, confidentiality and restrictive covenant agreements, and employment policies.

In a legal environment that often favors the employee, Millie has the experience, both in and out of court, to craft enforceable employee non-compete agreements, safeguarding your company’s interests and trade secrets when employees leave to start potentially competing businesses in the same space.

When complaints of wrongdoing within the company arise, Millie conducts thorough internal investigations to address the issue in-house and to prepare clients for possible outside enforcement or legal actions. During enforcement actions, she draws on her years of experience with state and federal agencies to effectively represent clients in government investigations.

Before joining Epstein Becker Green, Millie was an employment litigation attorney in the New York office of an international law firm and then in the London office of another international law firm.
