Professor Valenzuela really cares about his students. Even with remote learning during covid, his lectures were engaging and the assigned material provides great inspiration for the final research paper. Students get an overview of labor history and current labor campaigns. He also invites guest speakers who are active in those campaigns so they can give first-hand experience to reinforce the reading materials. The textbooks are actually books published by the UCLA Labor Center and they're very reasonably priced, you can get them in a bundle from the Labor Center website.
