In order to get maternity benefit in the form of paid leave, I think she should be an employee at the time of availing the leave. If she resigns in April, she will not come under the definition of employee when her delivery takes place. However, she will continue to get medical benefits till the benefit period ends, ie, 31st December, 2018.
I would like Shri Harsh Kumar Mehta to give his expert opinion on this issue. 19th January 2018 From India, Kannur
