Ensuring the rights and welfare of migrant workers is a crucial challenge, particularly in sectors like:

Construction
Domestic work
Informal sector
All of the above

The correct answer is: d) All of the above.

Migrant workers are workers who move from one country to another to find work. They often face difficult working conditions and are vulnerable to exploitation. Ensuring the rights and welfare of migrant workers is a crucial challenge, particularly in sectors like construction, domestic work, and the informal sector.

Construction is a dangerous and often hazardous industry. Migrant workers in construction are often exposed to dangerous chemicals and equipment, and they may not have access to adequate safety gear or training. They may also be forced to work long hours in difficult conditions.

Domestic work is another sector where migrant workers are often exploited. Domestic workers may be paid very low wages, and they may not have access to basic rights such as the right to rest and the right to freedom of association. They may also be subjected to physical and sexual abuse.

The informal sector is a broad term that refers to economic activities that are not regulated by the government. Many migrant workers are employed in the informal sector, where they may be paid less than minimum wage and may not have access to social security benefits. They may also be more vulnerable to exploitation and abuse.

It is important to ensure the rights and welfare of migrant workers in all sectors. This can be done by ratifying and implementing international labor standards, strengthening national labor laws, and providing support services to migrant workers.
