Workers rights cards, in English and Spanish, are produced by the US Department of Labor. The Migrant and Seasonal Agricultural Worker Protection Act establishes standards regarding wages, housing, transportation, disclosures and record-keeping. Among other provisions, the act prohibits retaliatory intimidation or discrimination against a migratory or seasonal worker who, with just cause, has filed a complaint or testifies or asserts a right relating to provisions of the Act. In order to operate legally, farm labor contractors must register with the Department of Labor.
