E/CN.4/2003/85/Add.2 page 14 40. Another consequence of the South Plan noted by the Special Rapporteur is the diversion of migrant flows to more inhospitable zones that entail greater risk, jeopardizing migrants’ right to life and physical integrity. In turn, the shift from the usual crossing zones to more dangerous areas has reportedly increased the demand for the services of polleros (people-smugglers) who, in many cases, extort money from, abandon or murder migrants whom they have supposedly agreed to guide. According to information received by the Special Rapporteur, at the end of May 2001 the Mexican police discovered in Veracruz the bodies of five Guatemalan migrants locked in a truck and abandoned by smugglers. The five migrants are presumed to have died of asphyxiation. VI. MEXICO AS A COUNTRY OF DESTINATION 41. The Special Rapporteur noted that Mexico is becoming an important country of destination within the region. She received information on the Migration Regularization Programme which the INM organized in 2000 and 2001. According to that information, the programme enabled undocumented migrants to obtain non-immigrant visitor status and authorization to work, provided the work and the employer were specified. She was informed that, in proportion to the number of migrants able to benefit from initiatives of this type, few persons had regularized their situation and that only those with certain levels of education, with sufficient money or with access to free legal representation had decided to obtain documents. The annual renewal of migration documents would appear to constitute another problem for migrants, and the organizations assisting migrants expressed the need to train the persons concerned to ensure that they remain informed and alert to the need for renewal. 42. In the south of Mexico the Special Rapporteur obtained information on the situation of women, children and men, mostly Guatemalans, who come to Mexico on a seasonal basis to work in the agricultural sector. The Special Rapporteur noted with pleasure the measures initiated by Mexico to provide individual documents for seasonal migrants, recognizing the specific contribution of women who also travel to work on a daily basis. This recognition is essential in ensuring the protection of their rights as women workers. In addition, the Special Rapporteur received information indicating that the working conditions of migrant day labourers are still very precarious, full respect for them is still a long way off and, regardless of their legal status, they are vulnerable to a host of abuses such as unjustified dismissal, withholding of wages and documents, excessively long working hours, ill-treatment and discrimination. They constitute abundant and cheap labour living on a poor diet and in deficient accommodation and health conditions. According to the testimony of day workers heard by the Special Rapporteur, the abuses most commonly reported are dismissal in the event of illness and the sexual harassment and rape of women day workers. The Special Rapporteur stresses the need to consolidate protection and regulation by the State and local authorities in this sphere. 43. Another particularly vulnerable migrant group is that of women in domestic service, who are mostly young, undocumented and of indigenous origin; they begin work at the age of 14 or earlier with the aim of helping their families financially. It was noted that almost all of them work excessively long hours for low wages and without health insurance. Many of them are
