Hello,
As per GRATUITY ACT, 1972 Section: 4, Gratuity shall be payable to an employee on the termination of his employment after he has rendered continuous service for not less than five years, - (a) on his superannuation, or (b) on his retirement or resignation, or (c) on his death or disablement due to accident or disease.
In simple term, an employee who completed minimum 5 years of continuous service is eligible for gratuity. Thus, in your case you, as you mentioned that you have completed 6 years in the same company, you are entitled to get the gratuity, no matter your company provides salary slip or not.
For your knowledge
The amount of gratuity can be calculated using the following formula:
Gratuity = No of completed years in company X Latest Basic Salary+DA X 15/26
Example
Suppose, your last basic salary + DA was Rs 25,000/-.
Gratuity = 6 X 25000 X 15/26 = Rs 86,539/-
