Question

how can be underemployment reduced

Answer 1

focus of education u can be reduced underemployment

Answer 2

First of all the cause of underemployment is due to poverty , family burdens etc.
This can be solved easily when government will increase job facilities and should attract the poor families by giving assurance that the government will bare the family income untill any person gets job in the family.
This is my idea.
Hope this helps you.☺☺☺
