Migrant workers play a vital role in sustaining essential frontline sectors. From healthcare and agriculture to transportation, and hospitality services, migrants fill critical labor shortages and bring diverse skills that keep societies functioning, especially during times of crisis. Their contributions increase economic stability and innovation while strengthening the communities they serve. Understanding the importance of migrants' impact on these frontline industries is essential to appreciating their place in the global workforce. Migrant Contributions to Global Frontline Sectors explores the lived realities, structural dynamics, and contributions of migrant workers employed in essential frontline sectors. It examines the tension between the indispensability of migrant labor and the invisibility of migrant workers in policy discourse, labor protections, and societal recognition. This book covers topics such as global business, digital technology, and transnational development, and is a useful resource for policymakers, business owners, academicians, researchers, and scientists.
