Longer notice period is given for the termination of my contract, which is beyond the requirement of Terms and Conditions.
In general, the employer may request the employee for longer notice period which allows sufficient time for handover.
In case the employee intends to give longer notice period but it is not necessary for the employer, the employer can waive the extra notice days proposed by the employee.
