Yes, Ms. Meenaxi, I think that our friends have answered the query from a general perspective of a proprietor working in his own establishment along with his employees. It is correct, but it cannot confer upon him the legal status or position of an employee.
Legal Perspective under the CLRA Act, 1970
Very particularly under the CLRA Act, 1970, the terms 'contractor', 'contract labor', and 'principal employer' do not stand in absolute terms but in relation to one another only. For the purpose of licensing a contractor under the Act, the same person cannot be both a 'contractor' and a 'contract workman'. In addition, the question of coverage of that contractor-cum-contract labor under the EPF and ESI Acts or EC Act would also arise. One cannot be both a 'contractor' and 'contract labor' under the CLRA Act, 1970.
Therefore, my above negative answer to the query is from such a legal perspective only and not about the contractor stepping into the shoes of any one of his contract laborers for the sake of expediency of the contract work.
