Dear Sneha Bansal, the Employee in question should determine, whether he comes under definition of Employee as defined under Sec 2(S) of Industrial Disputes Act, 1947
What Money is due to the Employee?
Leave matters (What Types of Leave under which Act?) can be taken up with Jurisdictional Labour Officer
can you please elaborate Termination without Notice period? Notice pay as per the Terms of Appointment Order has been paid or not?
Being a Managerial Employee, you should frame your question giving all relevant details for reply
