Mass political protests during the 1930s?

For an article in a university paper, I am collecting examples of mass social protests during the Great Depression of the 1930s. I've got a number of examples: the San Francisco longshoreman's strike, On-To-Ottawa March in Canada, the Bonus Army march in 1932, the Teamsters strike in Minneapolis in 1935. But can anybody think of any others?|||The Jarrow March was a protest demonstration by unemployed coal and shipyard workers, who walked from Jarrow in Northumberland to London, in order to draw attention to the troubles facing the unemployed during the Depression.|||there was a mass protest in washington d.c. by the world war


one vets and various labor protests in the 30,s50,s and 60,s|||The Bonus Army





Oh, and there were some protests in California about wages, but all of those were crushed.|||I think I found some more for you:
