full and final settlement

Well, as you are employed only a few months before, you could have waited for some more time for the company to issue you a business card.  Since you have worked only from Nov.2009 you cannot hardly fight for any compensation or any amount other than what you are eligible for the days you have worked.  Moreoever as there is no notice period clause neither the company nor you can claim any amount from each other.  As you have send the notice to the company you are eligible only for the amount (salary) for the days you have worked as stated supra.

mr.krishna, thanks for your reply. I am asking about salary only, not about compensation. what is the law regarding wages.

As regards salary issue, you are entitled to receive salary only for the number of days actually worked.

Well,

Supreme Court has (as far back as 1993) confirmed that principles of natural justice must be followed in all cases of termination of contracts and has clearly said that it is applicable to private companies as well and is violative of Art 14 and 21 of the constituition of India.

AP High Court has declared that a service contract with unfavorable terms including termination without a just cause, without due process as violative of Contract Act and against "public policy".

The notion that private employees (esp those belonging to non workman category) have no rights is ill founded (in my humble opinion). We do not have the forums like labour court, trubunals etc and thus we are left with Civil Court. But the law definitely is there to protect us in civil court.

Send me a private message if you are interested in some of these judgments..
