I have resigned from my organisation which is a psu to go for another organisation which is a govt of india establishment. It is clearly given in the service rules that the competent authority can waive notice period if the employee is going to another psu. But the authority is refusing my request for waiver citing that he will not waive the notice period since i have worked for 2 years. There is no possibility for the postponement of joining date in the psu that i am going to. Please suggest any methods which can prevent my paying them a huge sum of money
