Dear Colleague,
As per information furnished by you, you joined as Probationer in 2016 on a 6 months' probation. As of now you had totally you worked for 5.5 years without any confirmation letter.

You had raised basically 2 questions:

Your question is that whether you need to serve 3 months notice period?
In the event of no confirmation order normally the talent continues on probation but may be maximum for another 6 months time only. Certainly no one can be on probation for 5.5 years. All certain done, it is construed that you served as a Permanent Employee in the Company. Normally in case of Probationer the Notice Period is 1 month and for Permanent Employees the notice period is 3 months. Hence It is strongly suggested that you serve 3 months notice period on total and then get F&F/ get relieved smoothly.

Whether you are eligible for Gratuity?
With regard to Gratuity as you were appointed as Probationer and totally completed 5.5 years of service, you are entitled to get Gratuity under Payment of Gratuity Act 1972. You may apply for Gratuity if not paid by the company along with F&F. Normally the company will pay along with F&F. If for any reasons, your gratuity is denied, you may approach the HR of the company and claim your gratuity. If still it is unresolved, kindly raise a case before the Controlling Authority ( Assistant or Dy Labour Commissioner) who is the Authority under the Payment of Gratuity Act 1972 who will ensure that your grievance is redressed in line with the Legal Provisions upon merits
