Chicago CityMayor's Office issued the following announcement on June 10.
“Edward Sadlowski rose from working as a machinist's apprentice on Chicago's southeast side, to being elected shop steward of his steel mill, to leading the largest local Steelworkers union in America. He served bravely in the Army, and fought passionately for the rights of workers in Chicago and across America. Our thoughts and prayers are with his daughter Alderman Susan Sadlowski Garza, the entire Sadlowski family, and Ed's brothers and sisters in the labor movement on this difficult day.”
