Dear Renuka,
The case study posted by you of incident about child labour is incomplete. But as per your post, the two are the major person responsible for encouraging of child labour are:
1.the factory/tea stall/canteen where boy is employed, canteen owner is responsible for keeping child as servant/helper
2. The parent of the child is responsible who pushing his child for work in such a tiny age.
Both the person may get punishment under the child labour prohibition act_1986. We people of the society have duty to stop this type of activities, and encourage children for development of his career/life to go to school.
Thanks & Best Regards:
Vikas Ranjan
