A Latin American farm labourer is commonly referred to as a PEON. PEON is a Spanish term derived from the Latin word 'pedo', meaning 'foot soldier'. It is used to refer to a person who performs manual labor, such as a farm worker or a domestic servant. Peons are often employed in rural areas of Latin America, where they are responsible for tasks such as planting and harvesting crops, caring for livestock, and performing general maintenance on the farm.
