Ashish Yadav Secretary Bailadila Mine workers union in Dantewada Chhattisgarh says National Mineral Development corporation is cheating its non-permanent workers. They are around 500 of them and are mostly local adivasis. They get no details of their Provident Fund. Some get work for few weeks and then get retrenched. Workers are on strike from a month but no one is listening. You are requested to raise this with higher authorities. Yadavji@7857231323
