A/71/285 (c) Assist States in developing strong and effective labour law frameworks (including on labour inspection, unionization and collective bargaining) protecting the rights of all workers, including migrant workers, regardless of status, and in ensuring effective access to justice for mig rants whose labour rights or human rights have been violated; (d) Ensure that States adopt measures to facilitate accessible, regular, safe and affordable migration and mobility channels at all skill levels, as well as family reunification and the regularization of undocumented migrants; (e) Support the strategies of States, through fact-based analysis and long-term strategic thinking, to counter the conceptualizations of migration that underpin toxic public debates and counterproductive and ineffective security policies and needlessly result in the stigmatization, marginalization and criminalization of migrants, and integrate such analysis in developing means of public communication and elements of education curriculum in favour of migration, mobility and diversity; (f) Integrate IOM into the United Nations system, with a process leading to the updating of its Constitution in order to include in it a strong human rights protection mandate in favour of migrants, including the provision of an adequate level of core funding that allows IOM to take significant and forward looking initiatives in terms of migration policies and practices, and to not be merely project-driven; (g) Ensure, in all discussions relating to migration policies and practices, the participation of key United Nations agencies already working on migration issues, including OHCHR, ILO, UNHCR, UN-Women, UNODC, UNICEF and WHO, as well as United Nations human rights mechanisms, experts and civil society organizations; (h) Ensure that States collect disaggregated data, on the basis of data gaps, in order to develop meaningful, evidence-based policies while ensuring data protection through the establishment of firewalls, and support the increased harmonization and coordination of migration data sources, collection and analysis in order to develop a systemic picture; (i) Ensure a robust gender analysis of the difference in the impacts of policies on men and women, with special attention to the ways in which restrictions on women’s mobility as a means of protection violate their rights and create favourable conditions for smuggling networks to thrive, including the use of a gender lens at all stages and in all aspects of the discussion as specific consideration of gender in the context of bilateral agreements, detention/deportation and readmission/repatriation is also crucial; (j) Ensure that the detention of migrants is always a measure of last resort, permissible only when reasonable, necessary and proportionate, decided on a case-by-case basis, and enforced for the shortest possible period of time; develop rights-based alternatives to detention for most cases; and ensure that migrant children and families with children are never, ever, detained for reasons relating to their administrative immigration status. 24/24 16-13509
