A seasonal worker generally works in one to four month periods, most often in the building, construction, sugar, food preserves or hotel industries, or in agriculture, where, in the temperate zones, such workers are employed in grape, sugar-beet, potato, fruit and cereals harvests. In the tropical zones the work is mainly on cotton, coffee, cacao, rice and groundnut plantations. In the off-season, workers resident in the country may be faced with unemployment. Migrant workers for the season seek other employment elsewhere.
