Relieving letter not given

You may submit by letter under acknowledgment, to your appointing authority  :

your notice of resignation mentioning effective date of resignation, and ask for exit formalities to be completed,and to whom you should handover charge and company property.

You may prepare a list of company property with you if any  including ID card ,visiting card etc, and submit to designated employee under receipt with seal and signature, and ask to mention "Nothing is due".

You may submit this receipt along with your letter under acknowledgment to the concerned authority e.g HR Head and ask for NOC,F&F,work experience certificate,PF accumulation report,PF transfer forms,Form 16 etc by registred post.

These documents should be sufficient.If you have built good rapport obtaining company seal and acknowledgment from the desk where all company mails/courier  are received and to receive comment "Nothing is due" and other documents from your reporting authority/designated employee should not be difficult for you.

You shall have to act smart.

It is the employers decision to issue the relieving letter or refuse but you may ask for it by letter under acknowledgment.You can submit your representation if required to good offices of MD/CEO/CS.......

If you face any diffulty or problem is settlement you can lodge your greivance to Labour Officer, if you are a workman.

Hi Kumar, thanks for the reply.

So as per your comments can I conclude that employer is not legally bound to issue any relieving letter documents to employee leaving the organisation by submitting all required notices? 

Since I'm a software company employee, to which government authority can I approach?
