Dear,
As far as my knowledge is concerned, Gratuity is completely the employer's contribution. The employer can mention the gratuity contribution in the Appointment Letter, provided it is stated in the appointment letter that the employer would be contributing to the gratuity part, and the employee can claim his gratuity after completion of 5 years only.
In case an employee resigns before 5 years, the employee is not supposed to claim his gratuity amount (as mentioned in the Appointment letter - Gratuity is contributed by the employer). If an employee's tenure is closed with the organization before 5 years due to termination, then the employee can claim his gratuity amount.
For details, please go through the attachments.
Note: Always avoid mentioning gratuity contribution in any correspondence that needs to be handed over to the employee, e.g., salary slip, etc.
Thanks & Best Regards,
