He takes the time to learn about the businesses he advises and tailor their employee relation strategies to promote a better workforce and a better workplace. For those clients with established union relationships, Mark has worked diligently to further his clients’ labor relations strategies, including successfully partnering with their union representatives.

Clients appreciate the approach Mark takes in designing strategies that create internal response teams so that management and employees learn how to work together to address issues as they arise, which in turn fosters more open relationships.

His practice has a particular emphasis on assisting employers in lawfully responding to union organizing efforts; having been involved in over 100 union campaigns and having argued numerous traditional labor cases before the National Labor Relations Board and federal courts of appeal.

He has negotiated on behalf of management in collective bargaining negotiations and represented employers in dozens of labor arbitration cases, primarily across the manufacturing, retail and hospitality industries and in the public sector.

He also has deep litigation experience in the employment arena, including defending discrimination claims, restrictive covenant litigation, wage and hour issues, and ERISA litigation.

In his personal life, Mark is an avid hockey player and fan.
