dear
your husband has not completed 5 years of service ,so he is not entilte to get gratuity.
some people says after the judgement of madras high court that if individual has completed 240 days
in fifth year ,than individual becomes entilte for gratuity.But it is not correct because on the basis of one judgement there is no change in gratuity act.till the time gratuity act says that one is entitle to get gratuity after having 5 years of service.
