High Quality Content by WIKIPEDIA articles! Joseph Paul Glimco (January 14, 1909–April 28, 1991) was an Italian American labor leader and well-known organized crime figure based in Chicago, Illinois. He was considered "Chicago`s top labor racketeer" in the 1950s. One high-ranking Chicago Teamsters leader noted in 1954, "He is the mob. When he opens his mouth, it`s the syndicate talking." Glimco was active in the International Brotherhood of Teamsters (IBT) and a close associate of Teamsters president Jimmy Hoffa. He was a capo in the Chicago Outfit, an organized crime syndicate, and oversaw the syndicate`s labor racketeering efforts. He worked closely with Tony "Joe Batters" Accardo, who led the Chicago Outfit from 1947 to 1957, and Sam "Momo" Giancana, who led the syndicate from 1957 to 1966. A United States Senate committee once claimed that Glimco ran "the nation`s most corrupt union."
