Stanton previously rose in Chicago's underworld independently and later joined the Outfit somewhere around the early or mid 1930's and yeah, story goes that he was one tough, short-tempered and merciless motherfucker. He and Maddox took over the AFL Hotel and Restaurant Employees Union and the Bartenders International League of America. Maddox and Stanton controlled the Chicago Hotel and Restaurant Employees Local Joint Board and District Craft Council, in which all of the International's local unions held membership. The two gangsters plan was to destroy the local autonomy of all the member locals by setting up a master contract for negotiations with employers, thus the council would direct the destinies of over 35000 hotel and restaurant workers. Stanton mostly did the dirty work since he was a professional in intimidation and even killed few innocent people but the most interesting thing was that by 1940, Stanton belonged to the so-called “Big Four” in the union business, which also included Maddox, Murray Humphreys and Frank Nitto. This means that if he didn't got so much greedy, he might've rose in the organization on top level since he was a lucrative member and quite feared one. After the Stanton hit, the next year his brother-in-law and South Side gambler Robert Bock was also killed and Gus Alex was the prime suspect
