Many migrants are young, fit and healthy when they embark on their journeys, which is also known as the healthy migrant effect. However, difficult conditions throughout the migration cycle may negatively impact their health. Migrant workers, particularly those in irregular situations or working in informal sectors or without contractual safeguards, may be exposed to hazardous travel, exploitation and poor working and living conditions, including insufficient or absent labour protection and occupational safety. For instance, safety hazards are common in high-risk and dangerous employment sectors, especially manual labour. Many migrants who are low skilled are often employed in the so-called “3D” jobs (dirty, dangerous, degrading), in countries where labour protection and regulatory mechanisms are weak. Mining, construction and agriculture, for instance, have the highest rates of workplace injuries and deaths, and put young migrants at increased risk of occupational accidents and injuries (Migration Data Portal, 2021). Other employment sectors – such as domestic work, especially – put young migrant women and adolescents at risk of exploitation, violence and abuse, due to their isolation and confinement from protection and assistance mechanisms (Rijks, 2014).
This results in significantly higher risk of occupational injury and mortality (further details in Health and migration).
Migrant workers may also have disproportionately less access to health services due to, for example:
- Legal, administrative, linguistic and socio-cultural barriers resulting from lack of support from employers;
- Discrimination in the receiving communities;
- Fear of deportation;
- Lack of knowledge of their rights pertaining to employment contracts and related visa or immigration status.
Social exclusion and distance from family and support systems may further increase the toll on migrant workers’ health and well-being (see details in Integration and social cohesion and Family and migration). In addition to a combination of legal, sociocultural, behavioural, language and economic barriers, as well as difficult living and working conditions (such as lack of employer provided health insurance or paid sick leave benefits), migrant workers may have limited awareness of their rights or limited access to health and social services, which could impact their health outcomes. In such a situation, migrant workers may not come forward to seek health care and other social services. This may result in critical health conditions remaining untreated, and potentially also undermining overall public health, including during health or other emergencies. Healthy migrant workers are likely to integrate easily, be more productive and achieve positive outcomes for themselves and for their countries of origin and destination.
Many migrant workers undergo some form of health assessment or screening before their departure or upon arrival as a recruitment prerequisite. In many cases, due to poor data collection, testing practices may not be associated with referral for needed treatments and follow-up, making it difficult to assess public health consequences (Wickramage and Mosca, 2014). Mandatory testing for some conditions, such as HIV or pregnancy, and the lack of proper diagnostic practices and case management are of limited public health value and may lead to unnecessary exclusionary practices. For migration and pre-employment health assessments to meaningfully contribute to the greater public health good, and moreover to benefit the health of migrant workers, it is important to strengthen national health systems.
Governments and employers have the responsibility to ensure that migrant workers’ rights are protected. Multisectoral cooperation among, for instance, ministries of health and labour is a starting point for policy coherence regarding the health of migrant workers. The inclusion of migrant workers in national and employer health-care schemes can contribute to positive health outcomes not only for migrants themselves, but also for receiving communities, and can lead to increasing overall social cohesion. Mechanisms for extending social protection in health and increasing social security coverage for migrants and their families can enhance access to health services and avoid both excessive out of pocket payments by migrant workers in need of health services and unnecessary expensive emergency care. For instance, portable health insurance schemes through bilateral labour arrangements between countries of origin and destination offer migrant workers the possibility, in the present, to export their social benefits to families in the country of origin or, in the future, to export social benefits such as health care in old age.
