It is not known for what reasons your gratuity is forfeited. Generally, gratuity can't be forfeited. However, in exceptional cases where misconduct is duly proved in the inquiry, it is permissible. I know of a case from my previous company where the cashier was involved in the misappropriation of funds and subsequently dismissed from service. His gratuity was held. The person filed a court case. In the first hearing of the case, the presiding officer of the court advised both parties to arrive at an amicable settlement before it proceeds to a final decision on its merits because gratuity is a social security provision. The provision of gratuity is for the worker and their family as well. We have paid more than 50% of the gratuity to him, and the issue is settled. So without knowing the reasons for the forfeiture of the gratuity, further advice is not possible. It is understood that if you have an unblemished service record, then forfeiture is not permitted. Therefore, find out the reasons in writing from the bank and decide.
