Very strictly speaking, contract workers are to be regarded as our own employees, and as such, they are also eligible for minimum wages. The applicability of any labor law to a particular situation is judged based on the presence of an 'employer-employee' relationship. Even though the work is done by an outsourced employee, we have the right to reject incorrectly done work, implying the existence of an employee-employer relationship between us and the contract worker. Similarly, the contract worker can claim benefits such as minimum wages, ESI, EPF, etc.
