Minneapolis in the early 1930s was anything but a union stronghold. An employers' association known as the Citizens' Alliance kept labour organisations in check, at the same time as it cultivated opposition to radicalism in all forms. This all changed in 1934. The year saw three strikes, violent picket-line confrontations, and tens of thousands of workers protesting in the streets.Bryan D. Palmer tells the riveting story of how a handful of revolutionary Trotskyists, working in the largely non-union trucking sector, led the drive to organise the unorganised, to build one large industrial union. What emerges is a compelling narrative of class struggle, a reminder of what can be accomplished, even in the worst of circumstances, with a principled and far-seeing leadership.
