my friend is a government employee,he joined on ad-hoc base ,as assistant,at the time of joining some of his coleagues who were assistant got promotion and became assosiates within the period of two years, in 2007
after two year approx. organization hired my friend on contract basis for three years,in july 2009 for the same post .Organisation started giving arrears to all the employees in jan2009,
when the 6th pay arrears aplied to all of thoes employee in 2009,all thoes who became assosiate got all the arrears since they joined( as per assosiate pay scale ),
.but my friend got only two months arrears under the reason of he is on ad-hoc.
