Dear Dalia,
You can go for good option which is currently running by LIC.The number of average employees present in your company ,please take gratuity policy of LIC of fixed number of employees and submit monthly installments ,really this will help to minimize costing of your organisation.
Your organisation will be free at the time of gratuity given to the eligible employees.
If you could not find the ageny/LIC policy at your area,please send me request letter then i will provide you complete details on this.
Note: If period of employee stays is very short (1 or 2 years)then you should not go for this policy,but if your management feel about the employee welfare and reduce the company bearing cost then you should go for this policy.
Best Regards
Sajid Ansari
