Attorney Hynes has an outstanding reputation with his peers, as well as his adversaries. His credentials include being recognized in Wisconsin Super Lawyers – Labor and Employment Law (2005-2018) and Milwaukee Magazine's, "Best Lawyers" Edition (1999). Attorney Hynes is also President/Co-Chair of the Wisconsin Employment Lawyers Association, serves on the Board of Directors for the Wisconsin State Bar - Labor and Employment Section, and is a long-standing member of the National Employment Lawyers Association. A Wisconsin native, Jeff is a Phi Beta Kappa graduate of the University of Wisconsin-Madison and obtained his Juris Doctorate of Law degree from the UW Law School in 1984. 

The law firm provides legal advice, negotiation, mediation, and/or litigation services in the following areas:

  • Severance packages, separation agreements, positive employment references, health insurance benefits, and other matters relating to termination and job transitions;
  • Review/negotiation of non-compete, non-solicitation, confidentiality, retention and other employment agreements;
  • Responses to disciplinary warnings, performance improvement plans, poor performacne reviews, and other matters that may be harmful to the employee's career and/or reputation; 
  • Advice regarding disabilities, serious illnesses or medical conditions, medical leave, reasonable accommodation, and return to work issues;
  • Denials of raises, promotions or other employment opportunities;
  • Filings and responses to Equal Employment Opportunity Commission, State Equal Rights Division, Department of Labor, and other governmental complaints, investigations, or inquiries;
  • Settlement negotiations, mediations, or meetings with employers; 
  • Hearing and litigation before the Equal Employment Opportunity Commission, State Equal Rights Division, Department of Labor, and related government agencies, as well as in the state or federal courts;
  • Advice/negotiations regarding job transfers, demotions or firings;
  • Claims for unpaid wages, commissions or bonuses;
  • Claims for health insurance, COBRA and related employee benefit matters; and
  • Unemployment insurance appeals.


Our attorneys pride themselves on providing prompt, practical, and cost effective advice, with an emphasis on resolving workplace disputes through preventative legal counsel, and out-of-court settlement, where feasible. However, we will not hesitate to aggressively pursue litigation, if such option is in the best interest of our client.


Attorney Hynes brings a strong and diverse background to the table. He served as Staff Counsel to National Labor Relations Board member Patricia Diaz Dennis in Washington, D.C., and practiced labor and employment law with the reputable law firms of Jones, Day, Reavis & Pogue (Cleveland, OH) and Morgan Lewis & Bockius (Washington, D.C.), prior to returning to Wisconsin in 1988. His philosophy is to put the client's interests first, and to utilize the Firm's substantial legal skills and experience to obtain common sense, "win-win” resolutions for clients who are facing discipline, discrimination, termination, or other adverse consequences to their career, livelihood, good name or reputation. However, where voluntary resolution is not feasible, Attorney Hynes (and the other lawyers in the Firm) pledge to vigorously and forcefully pursue litigation and/or appeals to their logical conclusion, as the situation may require.
