analysis: The text appears to be discussing the rights and protections of migrant workers and their families, including their right to an effective remedy and protection from pressure to relinquish their rights. It also emphasizes the importance of states upholding these principles through legislation and other measures. Given the focus on labor rights and protections, it seems likely that the category will be related to employment or human rights.
