I agree with Rao Pulipaka, below is just an extract of the statement Bonded labour which is abolished by Indian Constitution long ago, but still illegally practised in india and even well educated are not aware of the facts when signing contracts with the new company.
Bonded labor, which is characterized by a long-term relationship between employer and employee, is usually solidified through a loan, and is embedded intricately in India’s socio-economic culture—a culture that is a product of class relations, a colonial history, and persistent poverty among many citizens. Also known as debt bondage, bonded labor is a specific form of forced labor in which compulsion into servitude is derived from debt. Categorized and examined in the scholarly literature as a type of forced labor, bonded labor entails constraints on the conditions and duration of work by an individual. but most forced labor practice are bonded labor. Contracts deny an indivi[/dual the basic right to choose his or her employer, or to negotiate the terms of his or her contract.
let me tell you CONTRACT is nothing but BONDED.
