Is It Legal for Companies to Bind Employees with Contracts Against Their Interests?

Is it constitutionally valid to have an employee bonded to a company irrespective of his interests?

I have joined an MNC, and they asked me to sign a 3-year bond. There is no training started, and it is about to start after 9 months. I found the work quite simple, and it doesn’t require an engineer like me to work on it. So, I don’t see any interest in working on it. Can I have a say in court, or is our constitution valid for bonded labor in companies? A lawyer's opinion would be appreciated.

If it is valid -

How can something be legal and declare my fate as I signed a bond before knowing the project they have and the work they are willing to assign?

Seen from the perspective of the Indian Contract Act 1872, the bond agreement is between parties who are competent to contract and is a legally enforceable agreement. The illegality arises when it is forced employment as per Article 23 of the Constitution of India, and whether the particular agreement amounts to it is to be seen from the entire facts of the matter. It is not that all employment bonds are bad, nor are all of them valid.
