Hi,
Would appreciate real honest replies to this :
1) how long was your employment tenure with the company.
2) Was there any act of misconduct or any misbehavior done by you.
3) How were your relations with your reporting manager.
4) Reason for you absconding.
If you cant answer here, ask yourself and get the answers to it, the reason why its necessary to know the answers to this. Is coz, by absconding you had chosen the wrong path, now to get your experience letter, you ought to make up for this, first of all going absconding and then asking for your experience letter after 3 long years itself raises a question on your professionalism.
However better late than you never, you need to realize and accept all your mistakes. Going to the court will only worsen the situation, there are things which could be done in a better way. Visit the office with all your documents i.e. your appointment letter, payslips, confirmation letter, increment letter if any. Speak to the HR,Speak to your reporting heads or managers (if they are still working there) apologize for what you had done. If required submit a written apology letter,and application for your experience letter.
For sure this will not be sorted so soon and easily, you will have to build a good relation with those in the office, making them understand that you are aware of what wrong you would have done, and have taken measures to improvise on the same. You will have to do continuous follow ups but without getting frustrated, in a nice cheerful manner.
But in all this, 1st thing you need to keep your temperament cool, and do not behave aggressively. Again to remind you many issues can be resolved by discussing it over with a cool head and warm words. Make sure you do not speak in any irrational manner.And kindly behave as a real professional now.
Each time that you meet the HR, after you leave the office, drop a mail about the discussion you'l head. Then atleast you'l have some written evidences.
