I have worked in one company for 3 years, getting good opportunity in another company I have given resignation with the 45 days notice, I have submitted my resignation functional dept head as well as hr dept, as per agreement 3 month notice period is there, After 45 days I relieved from the company, and they given letter stating that you have relieved so and so date. And subjected to proper handover the records that effect will be in your final settlement. I handover and taken no dues and the submitted in hr dept. the settlement cheque also made, the cheque has kept hold. I received call from HR and saying that your cheque is ready we need the clearance from your functional dept. I called the functional dept, they are saying that there is a pending working is there you have to come here and finish that work. It is not possible for me that to go again previous company, because I have joined recently in present company, asking leave is not possible in present situation.
Give the suggestion in my case.
