During the COVID time, the company had not given the increment to me but the manager had said that we will get the amount with all the difference in our next year increment but we didn't get any difference in our appraisal time, only set back is the manager had given the oral assurance of the difference amount, but he had said this to all employees. So there are witnesses to this. So can we sue the company on this basis? The difference amount is very much high
