Many migrant workers do jobs that are physically demanding. In the United States, 65% of farm workers are Latino. These workers often work in the agricultural or industrial fields. They might work long hours in the sun or use heavy machines. Some workers use chemical cleaners or pesticides that can cause health problems. These jobs are important, but they can be dangerous without the right safety tools.
Different countries have different ways of managing migrant work. In Canada, many people arrive using special work permits. In 2018, Canada issued about 495,000 work permits. 

Migrant workers help keep many parts of the world running. They work in many places like hospitals, schools, and farms. They also help build new cities and drive large trucks. Even though their work is hard, they provide important help to many industries. 
A migrant worker is an individual who moves to a different region or country to find employment. Most migrant workers do not intend to settle in their new location permanently. These people are often called foreign workers, expatriates, or guest workers. The term guest worker specifically describes those invited to work in a host country before they leave home. The International Labour Organization estimated that there were 169 million international migrants worldwide in 2019. 
In the United States, the migrant workforce is very large. There are approximately 14 million non-permanent workers living in the country. About 10.7 million of these are undocumented migrant workers. Many of these individuals come from Mexico and Central America to find occupational opportunities. They often seek work to provide economic stability for their families back home. However, the journey can be dangerous. Many workers face extreme heat or the risk of being caught by border control. Once they arrive, they may struggle with language barriers, cultural shock, and social stigma. 
Migrant workers in the United States often occupy roles in the domestic, industrial, and agricultural sectors. These jobs are frequently physically demanding and can be quite dangerous. In the agricultural field, workers perform intense labor for long days in extreme weather. They may face storms, intense heat, or exposure to pesticides, herbicides, and fertilizers. Such exposure can lead to respiratory illness, dermatitis, or cancer. In the domestic field, many female workers perform cleaning jobs using harsh chemical cleaners. Industrial workers might operate heavy machinery without receiving proper safety training.
Economic and social vulnerabilities often impact these populations. In the United States, 65% of farm workers are Latino, and about half are undocumented. This undocumented status can lead to exploitation by employers. Because of a lack of government regulation, some workers endure long hours for very low pay. They may also live in overcrowded or unsanitary conditions. The fear of sudden deportation can force workers to accept unlivable wages. Additionally, many workers lack health insurance to navigate the medical system if they become injured. They also face social discrimination due to labels like "illegal migrants."
Canada uses specific legal programs to manage its migrant workforce. Foreign nationals can enter via work permits, study permits, or asylum seeking. Most work permits are issued through the International Mobility Program (IMP). In 2018, Canada issued approximately 495,000 work permits. This was a significant increase from the 328,000 permits issued in 2008. Some permits are "closed," meaning they are tied to one specific employer. Others are "open," allowing workers to change employers. 
Since 1974, Canada has used the Canadian Seasonal Agricultural Workers Program (CSAWP). This program allows workers from Mexico and the Caribbean to fill labor shortages during planting and harvesting. In China, migration is a major part of the economy. In 2012, there were an estimated 167 million migrant workers in the country. Many move from rural areas to cities to work in factories or construction. However, the hukou system of residency permits can make it difficult for them to access social welfare. 
Migrant workers are essential to the global economy and various social systems. They provide the labor necessary for food production, construction, and healthcare. However, they are also highly vulnerable to the climate crisis. Because many work outdoors, they face higher rates of heat stroke and injury from storms. Their ability to access social resources is often limited compared to permanent residents. Understanding the movement of these millions of people helps us see how different countries rely on international labor to function.
