Normally the appointment order stipulates that the employees' service can be terminated by either party (employee or employer) by giving say, 3 months notice or ...( 3 months) months pay in lieu of the notice period. My query is, whether employer can retain the option of terminating the employee by giving 3 months notice period or 3 months pay in lieu of this and employee's option is only giving 3 months notice. That is employee DO NOT have the option to pay 3 months pay in lieu of notice period. Is it admissible under relevant laws?
