This is the eighth volume of Philip Foner's inexhaustible series on labor history in the U.S. I think I've used all the synonyms for "magisterial" in my reviews of the previous entries, so forgive me if I'm repeating myself.
This volume covers only two years, in the immediate aftermath of World War I. Foner's point of view comes through as in his other volumes. He routinely criticizes the AFL for lack of militancy and for commitment to craft unionism instead of industrial unionism. He discusses at length labor's relationship to the emergence of the Soviet Union in this time period and spends more time dissecting political activity of the socialist party and less on describing strike activity. He continues to hate Samuel Gompers.
If you gathered all the people in the country for whom this series holds great interest, we'd probably fit in a large hotel ballroom. Still, if you're in that group, this series continues to be an interesting left criticism of the history of labor in the U.S.
