Tom O’Heron, a retired director of collective bargaining for the International Association of Machinists and Aerospace Workers (IAM), has died at age 69. O’Heron began his career with IAM Local 21 in 1978 after training as a machinist and working at the Trane Company in Wisconsin. Over more than four decades, he held several leadership roles within the union, including Directing Business Representative for District 66, Collective Bargaining Coordinator, and ultimately Collective Bargaining Director before retiring in 2016.
O’Heron was recognized for his efforts to negotiate contracts that provided fair wages, benefits, and protections for IAM members. His work is credited with strengthening the union and benefiting its membership over many years.
“Tom O’Heron was a true trade unionist whose work shaped our union and improved the lives of countless working families,” said IAM International President Brian Bryant. “He will be remembered for his steady leadership at the bargaining table, his lifelong dedication to fairness, and his unwavering commitment to solidarity.”
Outside of his professional life, O’Heron was active in sports and community activities. He coached youth baseball and girls’ high school basketball teams, enjoyed golf and watching sports, and supported his granddaughters’ pursuits. He was also involved with the Knights of Columbus as a Grand Knight.
The IAM expressed condolences to O’Heron’s family, friends, and others who knew him, noting that his leadership and generosity would be missed.
