Boucher has written an immensely useful treatise on how a precarious, temporary, immigration status, or the lack of a valid immigration status, impacts the workplace rights that workers in four key high-income jurisdictions are able to exercise and enforce in practice. The Migrant Worker Rights Database, created by Boucher, provides a new source of data that will inform scholars and advocates alike about how different legal frameworks may facilitate or hinder the ability of migrants to enforce their rights. Boucher's findings will ultimately be invaluable for efforts to push for structural changes that better protect migrant workers around the world through regulation, legislation, and enforcement.
