Luiz Jiménez, 39, has been working on American dairy farms for 20 years. He is used to working long hours for little pay, fearful of losing a vital source of income for his family. A father of three, Jiménez is originally from Oaxaca, Mexico and came to the United States undocumented. He is one of an estimated 238,000 undocumented agricultural workers in the US. Like many others, he is without a visa, credit or health insurance, making it difficult to safely advocate for better working conditions without putting his livelihood at risk.
