A recognized authority on international labor standards, Stefan Marculewicz advises multi-national corporations on issues involving employer efforts to address and respond to international labor standards. He also advises multinational enterprises in connection with the following:

  • The International Labour Organization and its Committee on Freedom of Association
  • The Organisation for Economic Co-operation and Development
  • The United Nations Global Compact
  • The United Nations Guiding Principles on Business and Human Rights
  • Other international labor standard-setting organizations

He helps multi-national corporations based in the United States and abroad formulate and implement strategies to respond to efforts by labor unions and non-governmental organizations to discredit them through global campaigns. His work includes:

  • Development of global labor relations strategies
  • Developing supply chain management systems
  • Establishing corporate codes of social responsibility and human rights policies
  • Negotiating international framework agreements with Global Union Federations

He has represented employers before the ILO and OECD National Contact Points.  He also works with global employers regarding the design and implementation of human resources policies.

As a complement to his international practice, Stefan handles a wide range of issues related to labor management relations domestically, including:

  • Negotiating collective bargaining agreements for clients
  • Assisting employers in all aspects of their dealings with labor unions
  • Offering advice on corporate campaigns and neutrality/access agreements
  • Handling grievance arbitrations
  • Litigating complex RICO cases and class actions involving labor unions

Drawing on his experience as a trial attorney for the National Labor Relations Board in its Baltimore and Fort Worth regional offices, he also regularly assists clients before the NLRB.

Additionally, Stefan advises employers in connection with multi-employer benefit funds, particularly with respect to withdrawal liability, and has represented numerous companies in litigation involving such plans. He also advises employers on many other aspects of labor and employment law.

In 2012, Stefan testified before the House Committee on Education and the Workforce about the legal and practical implications of President Obama’s decision to make three recess appointments to the National Labor Relations Board at a time when the Senate was not in recess and still holding periodic pro forma sessions.

Stefan previously testified before the Senate Health, Education, Labor and Pensions Committee in opposition to proposed amendments to expand the Worker Adjustment Retraining and Notification Act, the federal law requiring 60 days advanced written notification of plant closings or mass layoffs.
