The Centre has asked states to incorporate certain provisions in the contracts of outsourced workers to protect their rights amid concerns about underpayment of wages and other benefits. The Ministry of Labour and Employment recently incorporated six statutory obligations on GeM (Government e Marketing) portal in the contract of hiring manpower through outsourcing agencies in Government of India offices in order to protect the interest of the contractual workers, a labour ministry statement said. Of late in a letter addressed to Chief Secretaries/Administrators of all States/UTs, Union Labour Secretary Arti Ahuja has expressed concern about the underpayment of contractual workers engaged in State/UT offices through outsourcing agencies due to unauthorized deduction in wages of such workers made by the manpower hiring agencies.
