Mark Weisman thrives on the immediacy and urgency of helping clients resolve labor and employment problems. He spent the first eight years of his career as a trial specialist and supervisory attorney for the National Labor Relations Board, where he represented the agency in administrative and federal court proceedings (particularly injunction matters). Through the experience, he gained an insight into how the NLRB and other administrative agencies investigate and decide cases.

In the past 30 years, Mark has represented many clients before various federal and state agencies, including EEOC, OSHA, MCHR, DOL, and IDHR. His previous NLRB work, coupled with this experience since leaving, enables Mark to provide timely and effective representation of both private and public sector clients that find themselves involved in matters before such agencies. His knowledge of NLRB law and procedure has enabled him to successfully negotiate numerous collective bargaining agreements as the chief spokesman for employers and to litigate many grievance-arbitrations arising under such agreements. From his initial injunction work for the NLRB, Mark has developed vast knowledge in representing clients in disputes involving work stoppages and strike violence where immediate court action is required.

Mark also counsels clients and litigates cases related to non-competition, non-solicitation, and confidentiality covenants in employment agreements. Mark strives to work closely with clients to devise sound and cost-effective solutions. His clients have come to depend on him for prompt, well-reasoned, and legally sound advice – not only in actual litigation, but also in the course of developing strategies and policies to minimize the risks of litigation. Mark frequently speaks to groups on a variety of labor and employment issues and keeps abreast of recent developments, particularly those involving the NLRB, as they may affect his clients.
