Sallary check

Salary Cheque is one of the evidences.

Believing that you arev from Delhi/around Delhi.

Try to obtain FULL free legal aid from counsels from Delhi and around areas. 

Request LCI experts from  Delhi and around areas. 

A cheque is not a proof whether it is for salary or for some other dues, as it never indicates on what account it is issued.

Either the employer is committing total violation of rules or you are unable to handle on your own.

So seek  help of either employee's/trade unions,officials in Dept. of Labor, a local counsel .
