Dear Malik,
Regarding your query on the subject, I would like to suggest that plz open the site "Haryana Labour Department" & then click on Haryana Labour Welfare Board. You will definitely find your answers of all of your queries. After going through this Act it reveals that leaving aside employer each and every employee is covered under tha definition of employee and thus they are to contribute to the fund but according to the latest minutes of the Board only the workers drawing wages upto 15.000/- pm are eligible to have the different welfare facilities as declared by the Board.
Hope that this will suffice your query.
With Regards,
R.N.Kho;a
