Michael Hanan is a Partner in the Employment practice group of GRSM, where he focuses on the representation of management in all areas of employment law. Michael defends employers against a broad range of employment claims from the inception of a lawsuit through trial, including wrongful discharge, discrimination, whistleblower and retaliation claims, disability accommodation, family leave and unlawful harassment. He has extensive litigation experience representing clients — which include Fortune 500 companies, privately owned companies, insurance companies and public employers — in federal and state courts, as well as arbitral and administrative tribunals. He has successfully defended cases on behalf of his clients through trial in each of these tribunals.

Michael also has successfully litigated contentious post-employment restrictive covenant cases involving confidentiality of trade secrets, non-competition and non-solicitation clauses. He also defends companies against public access disability cases related to both physical premises and websites.  Additionally, Michael regularly provides advice and preventive counseling on all aspects of the employment relationship, including the creation, implementation and enforcement of workplace policies and the investigation of harassment/discrimination claims. He works to help clients navigate through the complexities of federal, state and local laws, and implement prudent, cost-effective strategies that address employment issues as they arise.

Upon graduation from law school, Michael had the privilege of serving for the first four years of his legal career as a New York City Assistant Corporation Counsel in the Civil Rights trial division, where he obtained defense verdicts on behalf of New York City and its agencies in several civil rights trials, including employment discrimination trials.
