Sitting next to her is a group of 13 daily labourers, including her husband and her extended family members, from Uttar Pradesh's Banda district.
The group left their homes early last month to work in a brick kiln in rural Ghaziabad
How will my family, including three sons, survive if we can't harvest the crop. And if I am not there, who will do it?
