What options do i have now to recover my dues ? legally as well.

Hi Ramesh,
7months is just too late and I can see the employer does not want to pay you? Immediate send a legal notice through an advocate.

Due you have the attendance record proof to demand Salary ???
Have you not signed any letter i.e. offer/appointment or Standing Orders during your tenure with the company
Did you received all other papers with regards to your relieving experience extra before filing/approaching the legal. The reason behind asking is that once you go legal it should not back track you and will spoil your career.

Dear Ukmitra,
Thanks for your guidance.Are my paper work is sufficient to go legally....what would be the cost for going legal and time frame to get an result?

Dear Saji,
There is no appointment letter/offer letter/salary slip/attendance record with me. On my request they had issued me salary certificate on letter head signed by owner with seal and sign.I have one long mail trail follow up for salary,he has personally responded confirming that he will pay me.

Dear Ramesh,
Was there a PF deducted from your monthly salary and do you have your PF no? Are you presently employed? In that case, you can approach the Labour department and file a case. Hoping that you have received all the documents and only the final salary/settlement is pending. Would be better if you could consult a Statutory Consultant with all the relevant documents before hand.

Dear Mahesh,
No deduction for pf in previous and existing company.they had issued me salary certificate on letter head signed by owner with seal and sign.I have one long mail trail follow up for salary,he has personally responded confirming that he will pay me.
what options do i have with existing paper work?

Dear Ramesh,
Please check with a Statutory Advocate and initiate a notice to that company for your pending salary and the interest on the amount, for the period it is kept on hold.

Dear Ramesh,
In my opinion, if your single signature in any papers of company, is a valid proof to fight legally with company.
You could file a case in labour court, and believe, 99.99 % decision are come on favor of employee in labour court.
Send him a legal notice and look the effect. He will surely respond you.

Dear Surendraji,
