Dear Mr. Rinkesh, you have concluded with excellent words: "Be Humanistic." Fantastic.
Humanistic Approach in Employment
Both ways—from the employee side and from the management side—being humanistic does apply, along with the performances of the employees, which keep them in employment in the same organization for 4 years and 240 days or so.
Hence, considering the aspects of benefits, other good things, or even gestures the employee enjoyed from the management of the company, the employee can also be humanistic to continue with the same job (to complete the 5 years in full to become eligible for gratuity under the Gratuity Act).
Still, if the employee gets a much better opportunity and the future employer cannot wait, then the option is very much in the hands of the employee on how to get compensated for the losing amount by way of gratuity.
For example, Mr. A or Ms. B is drawing 20,000 (basic + DA) and worked for 4 years and 240 days. Then the gratuity amount (which is being argued above) would work out to Rs. 20,000/26 days x 15 days x 5 years = 57,692 / 12 months (comp: 4,808) or 57,692 / 18 months (comp: 3,205). The employee who decides to quit can as well add up this much amount with their expectation, and both ways it suits; the future employer is going to offer the package the employee finally settled in for.
Humanity and Integrity from the Employee
Hence, the humanity (or integrity!) too should come from the employee. Having enjoyed the benefits of the company for 4 years and 240 days, the same employee can as well be "humanistic" to the management.
He or she can either wait for the completion of 5 full years, then try for other jobs, or he or she should be ready to forgo the gratuity from the present organization (if at all the company strictly follows the gratuity applicability rules) and be smart enough to get compensated from their future employer by adding to their expected package.
This won't be applicable to the organization or company that would be kind enough to consider paying the gratuity amount to an employee who preferred to leave after serving 4 years and 240 days, which is being argued as above.
Regards,
Sundararaman
