Resignation notice usually takes the form of a letter (commonly called “resignation letter”) addressed to the employer, expressing the employee’s intention to terminate his employment. The notice of resignation must be in writing and must be served to the employer at least one month prior to the effective date of his resignation.Resignation is defined as the voluntary act of an employee who finds himself in a situation where he believes that personal reasons cannot be sacrificed in favor of the exigency of the service and he has no other choice but to disassociate himself from his employment. In one case, the Supreme Court held that a memorandum written by the employee containing his deep resentment towards his superior juridically constituted a letter of resignation. However, lack of explicit words stating the employees intention to resign is deemed not crucial, as long as the employees intention to resign can be deduced from letter itself.
