Dear Geet,
Maternity Leave Eligibility
She is eligible for Maternity Leave of 12 weeks. However, the employer may be reluctant to grant more leave at the outset and in one go. In any case, an 8-month leave (even without pay) is rare and may not be allowed under their company policy. What one can do is avail the statutory leaves as per the Act (which cannot be denied); and then, if the need arises on the basis of medical grounds (or otherwise), apply for appropriate leave subsequently.
That is what I can suggest. Other members may be better able to provide more ideas or suggestions on this issue.
Warm regards.
