Former New York City labor leader Victor Gotbaum has died at the age of 93. Gotbaum led the country’s largest municipal workers’ union for over two decades, beginning in 1965. Under his leadership, District Council 37 of the American Federation of State, County and Municipal Employees, or AFSCME, became one of the first unions to publicly oppose the Vietnam War, and saw its membership more than triple. Known for his militant organizing, Gotbaum is also credited with helping to save New York City from financial ruin by striking deals with bankers and City Hall. He died after a heart attack on Sunday.
