Dear Sanjay,
Definition of contract labor
The definition of contract labor basically states that any person working on your premises under an agreement with their direct employer to deliver a result, other than the pure sale of goods, is a contract worker (except those in part-time or purely administrative roles).
Principal employer responsibilities
Regardless of whether the individual has a labor supply contract or a job contract, the responsibility and liability remain the same for the Principal Employer (PE). The determining factor for applicability is whether the workers (not necessarily the same individual) regularly work on your premises.
License applicability in Maharashtra
In Maharashtra, the threshold for license applicability has been raised from 20 to 50 workers, eliminating the need for a license. There is an ongoing debate (not yet resolved by courts) regarding whether the act applies even when a license is not required. To safeguard yourself, ensure verification of fair wage payment (including minimum wages), overtime at double rates, provision of required leaves and holidays as per the law, and payment of all statutory dues.
Compliance with safety regulations
Additionally, ensure compliance with safety regulations and, if ESIC (Employees' State Insurance Corporation) does not apply, confirm the presence of a workmen's compensation insurance policy. As mentioned by Madhu-ji, avoid direct involvement in controlling or managing the contractor's employees, except as necessary for quality control purposes.
By adhering to the above guidelines, you are less likely to encounter issues.
