Harsh working conditions refer to the difficult, unsafe, and often inhumane environments that workers endure while performing their jobs. In the context of the rancho system and land grants, these conditions were characterized by long hours, low wages, and a lack of basic rights and protections for laborers, particularly those from marginalized communities such as Indigenous peoples and Mexican laborers. These factors contributed to a system of exploitation that was integral to the economic success of ranchos during this period.
