In Andhra Pradesh, where a contractor engages five or more contract laborers, the contractor should have a license, and the employer must get it registered with the appropriate government. Furthermore, the principal employer is responsible for the payment of wages and remittance of all statutory deductions like ESI, PF, etc. However, the contract laborers have no right to claim permanency in the organization belonging to the principal employer. If the employer doesn't have registration and engages contract labor, then there will be a problem; the contract labor may become regular employees. This is my personal opinion.
