Sanjay,
If you initiate and help the workers in forming a cooperative/forum/union and outsource work to that body to prevent exploitation of workers, then it is a capacity-building/poverty alleviation program that can also be included in CSR initiatives.
On the reverse side, workers can also form groups on their own, and work can be outsourced to them.
The Ethical Trading Initiative (ETI) for homeworkers emphasizes such exercises. In the garment trade, there are plenty of poor/destitute women engaged in embroidery work at home. The work reaches them through the hands of scores of contractors.
ETI wants the principal employers to map the entire value chain so that end workers can be identified, and their conditions can be improved.
We encourage workers to gather at a common place like a Panchayat Bhavan in a village and do their work there.
ETI also talks about multi-stakeholder initiatives. For example, we aim to provide medical insurance to the unorganized sector.
All players in the value chain, including the end workers, contribute their share, which is quite small, approximately 200/- per annum, even cheaper than ESI.
Next, you can encourage them to form a "Bank/Microcredit facility" too.
Keep us updated so that everyone can learn.
