It is with great sadness that we announce the passing of our Brother and Retired Business Manager, Michael R. Murphy, who passed away peacefully at his home on August 24, 2025, surrounded by his loved ones. A proud Local 99 member for 50 years, Mike served as Business Manager from 2003–2016, leading membership growth, expanding education programs, and overseeing the move to our current Union Hall, “Engineer Center.”

Even after retirement, Mike remained active in Local 99 and the labor community, always standing up for working people. He was a true trade unionist, a leader, and a friend who will be deeply missed.
