You may refer to your appointment letter and terms of temination of service.
The terms should encourage equality.
If the employer has stated that employer can terminate without assigning any reason or notice or notice pay, but employee can not,
or employer can terminate by notice or notice pay in lieu of it but employee can not,
then the contact is heavily weighed towards employer.
However if you have any situation it is better to be smart, persuasive, and negotiate and concude it to the benfit of both paeries than to land up with complications and litigation.
However if there is no other recourse,you may show your docs to your lawyer/law firm and submit resignation:
-with cheque/DD of notice pay (basic/gross/CTC as defined in appointment letter and nothing is defined basic pay).
-or ask them to adjust notice pay in F&F and supply the same to you, so that you cans pay the difference if any.You should also demand your work experience certificate,form 16,NOC/NDC,PF accumulation reports, PF withdrawl/transfer forms,releiving letter etc......by registered post.
Sumit company property and obtain receipt.
