The Italian immigrants in particular brought a radical, largely anarchist labor movement to Barre. In the 1920s and 1930s, a number of granite strikes roiled the city; some disputes concerned wages, but workers increasingly mobilized to address health and hazard in the quarries and "sheds." The strike of 1922, arguably fought to a draw, raised ethnic tensions; French Canadians were painted as strikebreakers. The Quarry Workers' International Union of North America was based in Barre. They were originally affiliated with the Socialist Labor Party before affiliating with the Industrial Workers of the World, and in 1916 and in 1929 the city elected a Socialist Party candidate as mayor of Barre. The old Socialist Labor Party Hall is still standing, and was listed on the National Register of Historic Places in 2000.
