The provision is as below :
Section 4(6) provides as under:-
“Notwithstanding anything contained in sub-section (1)
(a) The gratuity of an employee, whose services have been terminated for any act, willful
omission or negligence causing any damage or loss to, or destruction of, property
belonging to the employer, shall be forfeited to the extent of the damage or loss so caused;
(b) The gratuity payable to an employee may be wholly or partially forfeited;
i) if the services of such employee have been terminated for his riotous or disorderly
conduct or any other act of violence on his part, or
ii) if the services of such employee have been terminated for any act which constitutes an
offence involving moral turpitude, provided that such offence is committed by him in the
course of his employment.”
So, yes, he can be terminated for moral turpitude.
