Yes you can represent to your employer and claim gratuity. But you should present some proper reason for delay in applying for Gratuity.
"An employer cannot reject an application by the employee after the expiry of 30 days, if the delay happened due to a valid reason. The rules further clarify that no claim for gratuity shall be invalid merely because the claimant has not filed his application within the specified period."
In case the Employer is dilly dallying the gratuity claim, the employee claim his/her gratuity in Form I marking a copy to the Controlling Authority.
