Historian Melvyn Dubofsky, however, offers a different perspective. In Minnesota, for example, the miners went on strike in 1916 to abolish the contract system, to secure a minimum wage, and to end exploitation by the company. They approached the AFL and the WFM, both of which failed to respond. Dubofsky notes, "IWW headquarters had been advised of employee discontent on the eve of the ... and the IWW instantly had organizers on the spot." Dubofsky states that the walkout occurred without IWW involvement, and he describes the evidence for this as "incontrovertible". The IWW was approached for help and, according to Dubofsky, the IWW "achieved its aims not by coercion but by giving the striking miners leadership, funds, and publicity."
