They would also need to tell whether the workers are getting that minimum number of days as leave or not," said a senior official.

The move comes after an internal finding of the labour department that the workers even in the outsourced works in the city government are being exploited by the private companies on a largescale.

"If the labour laws are not implemented even for the workers engaged in the government's outsourced work, it would be least likely that it would be respected by other employers. The department is attempting to set a standard through this so that the other employers can take note of it and start adhering to the labour laws voluntarily," added the official.

With public-private partnership (PPP) being the buzz word in the functioning of the city government, the official said, a large number of people are getting employed by the private firms for the public works.

As per the Delhi Cabinet's decision taken last year, the city government is soon to outsource the works of nurses, sanitation, canteen, security and maids in the hospitals and health centres to the private agencies. If the Delhi Cabinet gives its assent to the proposal, even the outsourced work of the civic bodies would come under the ambit of the labour department's initiative.
