In response to a public complaint filed with the Secretary of Labor alleging discriminatory practice by the Rural Manpower Service (RMS), an investigation of the charges was conducted. The petition was filed on behalf of 16 organizations and 398 specifically named individuals, and it accused the RMS of exploiting migrant farm workers. The methodology of the review included an initial analysis of the alleged problem, the accumulation of background information, field visits, and the organization and analysis of the information gathered. The overall findings and conclusions of the review in the initial major section are divided into 2 parts, dealing with the role of the RMS and the role of worker advocacy. The findings are discussed by topic under 3 sections: (1) economic and legal condition of the farm worker, including discrimination, certification of foreign workers, social security, wages, child labor, and labor law enforcement; (2) services to workers, including referral control, job order specifications, employment services to workers, conflict of interest, farm labor contractors, statistics and staffing, and day haul; and (3) working conditions, including housing, safety and pesticides, field sanitation and drinking water, and transportation. Green card commuters and illegal aliens are discussed in the 2 appendixes. (HBC)
