Edward Fitzsimmons Dunne for Mayor of Chicago. Violence broke out and continued almost daily until mid-July. Riots occurred on April 7 when Montgomery Ward attempted to use wagons driven by strikebreakers to deliver raw materials and finished goods. The most serious that day involved 1,000 striking workers and sympathizers, who attacked several heavily guarded wagons on Union Street. On April 29, a crowd of 1,000 striking workers and sympathizers clashed with police, and three people were shot and two stabbed. Mayor Dunne immediately banned the carrying of firearms. On May 4, a riot involving more than 5,000 people coursed through the city's streets. Strikers hurled bricks and stones, and assaulted any African American or wagon driver caught on the streets. Police, strikers and strikebreakers used clubs and firearms against one another. During a stone-throwing melee on the Rush Street bridge, strikebreakers opened fire on striking workers, leading to one death. "Slugging"—the beating of non-union workers or union members who crossed picket lines—became common. The EA mustered its substantial resources to break the Teamsters' support for the striking tailors. The EA collected $250,000 (about $6.7 million in 2017 dollars) from its members to hire strikebreakers. The EA also raised $1 million (about $27 million in 2017 dollars) to establish, on April 13, the Employers' Teaming Association-a new company which, within a matter of weeks, bought out a large number of team owners and imported hundreds of African American strikebreakers from St. Louis to work as teamsters and drive the wagons. Mark Morton, president of Morton Salt and an EA member, convinced the railroads to pressure the remaining team owners to lock out their Teamster members as well. In response, the unions organized a boycott of all banks involved in the fundraising efforts. With the garment workers' strike all but forgotten, the tailors' union asked that the other unions end their sympathy strikes. The Teamsters, the critical union in the strike, agreed to do so if the employers would agree to rehire all striking workers. But on April 23, Montgomery Ward declared it would defer to the decision of the Employers' Association, and the EA announced a day later that no striking workers should be rehired. Infuriated, the Teamsters called another 25,000 members off the job on April 25, 1905, paralyzing grocery stores, warehouses, railway shippers, department stores and coal companies. On April 30, the EA and its members then sued nearly
