Jean Marc Favreau
Jean-Marc represents and advises public and private sector labor unions in a variety of areas of labor law including arbitration, collective bargaining, NLRB proceedings, organizing campaigns, and union governance.  He also advises and represents individuals, including clergy, educators, and other professionals, in employment matters such as contract negotiations, retirement agreements, and severance agreements.

Jean-Marc frequently conducts steward trainings, labor rights seminars, and arbitration courses for unions, and has written and presented on a diverse array of labor and employment issues. He previously served as an adjunct professor of law at the Catholic University School of Law.

In this role, he helped to successfully draft, negotiate, and implement the first collective bargaining agreement in history to cover staff members of a U.S. presidential political campaign.
