But now I got a good opportunity in new restaurant after so I want to leav the current job.when I gave my resignation to my manager they denied to accept it and next day when I came on the shift they terminate me without any prior notice.when I told them I am agree to give u full one month of notice period.but they didn't listen me and told me return the uniform and go at home no need to come again here.then I came back at my home.but after few days I visited that restaurant where I used to work for my experience letter they gave me my experience letter apart from that they gave me a form of NO DUES FORM and they get it signed by me.after that when I told them sir will I get all my dues like SERVICE CHARGE MY SALARY???? They clearly told me we will not give u anything because u give a resignation immediately effect so we can't give to u anything dues.
