  • Coordinated employer response in numerous strike situations including a work stoppage across 14 western states of the client’s operations.

Mark has extensive experience representing employers in all matters before the NLRB, including representation petitions, jurisdictional disputes and the handling of unfair labor practice charges from the date they are filed through trial and appeal. Mark has acted as lead negotiator for dozens of major companies in a variety of industries, including national, multi-unit, multi-location, multi-employer and multi-union bargaining. Mark has handled lockout and strike situations, coordinating the clients efforts.

In addition, Mark has handled hundreds of arbitrations involving virtually every area of dispute, including contract interest arbitration, contract interpretation, just cause termination/discipline, benefits, pay rates, and hours of work.
