Please help me its very important.

Dear Sangeeta,
GPA and WC Insurance policies are different in scope and scales of insurance offered. While the WC Insurance policy covers the entire liability of the employer under the Employees Compensation Act,1923 the GPA is limited to the sum assured only and subject to the conditions stipulated in the policy note. Moreover, it can not be a substitute for compensation under the EC Act,1923, if I remember correct.
