IAM General Secretary-Treasurer Dora Cervantes has appointed Stephen Stewart, a longtime member of IAM Local S6, as an International Auditor for the International Association of Machinists and Aerospace Workers (IAM), effective October 1, 2025. In his new position, Stewart will oversee financial matters for IAM Districts and Locals in Maine, New Hampshire, Massachusetts, Vermont, Connecticut, Rhode Island, and New York.
“Stephen Stewart has consistently demonstrated the highest level of integrity, dedication, and skill in every role he’s held in our union,” said IAM General Secretary-Treasurer Dora Cervantes. “His leadership at Local S6 and District 4 has shown that he understands the responsibility of financial stewardship and the importance of transparency to our members. I have no doubt he will excel as an International Auditor and serve our membership with distinction.”
Stewart joined IAM Local S6 at Bath Iron Works in 2011. Since 2020, he has served as Secretary-Treasurer for Local S6. He was active on the Legislative Committee and participated in the 2023 Negotiating Committee. In 2023, Stewart was elected Recording Secretary of District 4 where he provided oversight on finances and organizational support.
“IAM Assistant Secretary Paul Kendall said: “Stephen’s experience in financial oversight, negotiations, and legislative advocacy gives him a well-rounded perspective that will be invaluable in his new role. He knows what it takes to keep our Locals strong, accountable, and member-focused.”
Stewart has represented union members as a delegate to several organizations including the Maine Machinists Council, New England Machinists Council, A. Philip Randolph Institute, Maine AFL-CIO, and attended the 2024 IAM International Convention. His past roles include service on Education and Organizing Committees along with advocacy for working families in Maine.
Bryan Pinette, IAM Special Assistant to the General Secretary-Treasurer stated: “Stephen has an incredibly strong commitment to our members. His appointment as International Auditor is well deserved, and I’m confident he will be a tremendous asset to our team.”
Stewart graduated from Lake Region High School in Naples, Maine before attending Bryant College. He also completed technical training through the Maine Maritime Apprenticeship Program at Bath Iron Works and participated in multiple IAM training programs focused on leadership and finance.
With his background in financial management within union settings as well as negotiation experience and ongoing commitment to IAM members’ interests across several states in the Northeast United States, Stewart joins the IAM International Auditors team with relevant expertise.
