1. Dear member, in the contract proforma as enclosed by you above, there is mention of "Consolidated (compensation" (para 3). But there is no reference relating to benefits under Maternity Benefit Act, 1961. In this connection, I am enclosing herewith copies of one judgments of High Court, which I think will be relevant in your case. You can also download other judgments mentioned in this judgment and study the same.
2. Further, I think, ECHS organisation has been established since more than 10 years earlier and during such long years, I think, there must be such cases of woman employees on contract basis, who may have claimed maternity benefit. In my opinion, you can search from other units of ECHS offices.
3. However, I may also submit that in India, the compliance position of labour laws is very poor. The State itself is discriminating for providing social security benefits to its woman employees. Further, I think, you can make further inquiries or obtain information through RTI etc. and can also make grievance through proper channel, if allowed as per your terms and conditions of employment.
