I employed with one organisation. I worked for 25 days and due to some personal problem i am forced to relieve from that organisation. I dint inform them prior but i sent a mail formally about my resignation. Later i got a letter from that organisation like i need to survive the notice period or i have to pay the short fall notice period of $7000. I again sent a mail like both physically and mentally i am, not in a position to work but still they are threatening that they will take legal actions against me.Also for the 25 days i survive i dint assign to any work i was totally idle on those days. Please advice how to handle the situation. Is it really possible for them to take a legal action even though i am not ready to work for them.
