Referring to question #1, I am a researcher at Loei Rajabhat University in rural Thailand. From my perspective, child labour is necessary in some cases, so that they can feed themselves and pay for their studies. It's not as prevalent as in past years. In many cases, the ideal family is very strong. This compels children to want to contribute to the family income. There are two cases. Children from poor families may leave school to work to contribute to their family's income. The parents may be migrant labourers and the children follow the parents. They may have to operate machinery or do other dangerous work. This type of work is not appropriate for children. Other children work only after school and during the weekends. Still, others are forbidden to work by their parents.
Referring to question #3, The Thai law has a child labour policy that is in accordance with the International labour convention prohibiting employment of 13-year-old and younger children working during school hours, and then only with approval for out of school and weekend work times. Moreover, the government set up a labour policy for 15-year-old children so that they can access labour welfare as a normal worker for employment, taking sick leave, and time-off. These laws have led to fairness for children and their lives.
