In Dubious Battle is a novel by John Steinbeck, written in 1936. The central figure of the story is an activist for "the Party" (possibly the American Communist Party or the Industrial Workers of the World, although it is never specifically named in the novel) who is organizing a major strike by fruit pickers, seeking thus to attract followers to his cause.
Prior to publication, Steinbeck wrote in a letter:
This is the first time I have felt that I could take the time to write and also that I had anything to say to anything except my manuscript book. You remember that I had an idea that I was going to write the autobiography of a Communist. ... There lay the trouble. I had planned to write a journalistic account of a strike. But as I thought of it as fiction the thing got bigger and bigger. It couldn't be that. I've been living with this thing for some time now. I don't know how much I have got over, but I have used a small strike in an orchard valley as the symbol of man's eternal, bitter warfare with himself
