Michael A. Warner, Jr.


Mike represents both private and public sector clients in all aspects of labor and employment law, with a particular emphasis on litigation, arbitration and other forms of dispute resolution. Mike also uses his substantial trial experience to provide day-to-day counseling to employers on how to best achieve their business objectives while limiting the risks of litigation.

Mike has wide ranging experience representing employers before state and federal courts in multiple jurisdictions, the EEOC, and numerous state and federal agencies in single-plaintiff and class action employment discrimination, harassment, wrongful discharge, wage and hour, defamation and breach of contract cases. He also represents employers in labor arbitrations and in employment related arbitrations before the Financial Industry Regulatory Authority (FINRA). In addition, he routinely represents and counsels clients in trade secret, and non-compete agreement disputes in which he has successfully brought and defended claims for emergency injunctive relief.

Mike represents companies in the telecommunications, energy, technology, retail, manufacturing, insurance, financial services and transportation industries, and also represents municipalities.

Before joining the firm in February 1995, Mike practiced commercial litigation with Sidley & Austin (1993–1995) and served as a law clerk to the Honorable Judge Robert L. Miller, Jr. of the U.S. District Court for the Northern District of Indiana (1991–1993).  During law school, Mike was the editor of the Northwestern Journal of International Law and Business

Since 2007, Mike has been recognized as an Illinois Super Lawyer in the area of employment litigation defense by Law & Politics.

Mike is a founder and board member of the ENABLE Scholarship Fund, which awards private high school scholarships to low-income adolescents.  Mike also volunteers in the Constitutional Rights Foundation Chicago’s “Lawyers in the Classroom” program with Dvorak Academy, the firm’s Chicago Public Schools’ partner school.

Mike, an active member of the Logan Square community on Chicago’s Northwest side, has served as president of the Palmer Square Homeowner’s Association, is member of the 35th Ward Zoning Advisory Committee, and is a member of Logan Square Preservation.  In his spare time, Mike is an avid skier, and a still-learning wine maker and collector, despite the conspicuous lack of mountains and vineyards in Logan Square.

Representative Experience  click to view

  • Represented a leading telecommunications provider since 2005 in more than 50 labor arbitration matters against the International Brotherhood of Electrical Workers (IBEW) and Communications Workers of America (CWA) and 15 employment litigation matters in state and federal courts throughout the Midwest.
  • Obtained a significantly favorable judgment for a major national retailer in a race discrimination, whistleblower retaliation and FMLA retaliation case brought by a former human resources director. A federal district court in New Jersey not only dismissed the employee’s claims in their entirety, but also awarded attorneys’ fees in favor of the retailer on a counterclaim asserting that the employee breached a binding confidentiality agreement by taking confidential company documents that she claimed supported her lawsuit.
  • Defended a multinational conglomerate in the electrical distribution and factory automation industry in a lawsuit brought by a former in-house patent attorney alleging claims of defamation and tortious interference arising out of the attorney’s termination for misconduct. Successfully obtained injunctive relief preventing the former lawyer from disclosing or using confidential, privileged and proprietary information in support of his claims.
  • Obtained injunctive relief and a substantial monetary settlement for a major financial institution alleging that former employees hired by a major competitor had breached a non-compete agreement and misappropriated trade secrets. Representation included injunction proceedings in Florida state court and arbitration proceedings before the FINRA.
  • Defeated a motion for a temporary restraining order and obtained a favorable settlement in an action alleging that a medical device and pharmaceutical company stole trade secrets of a competitor and induced the breach of a non-compete agreement through the hiring of a competitor’s top executive.
