This agreement creates a firm arrangement between the parties to guarantee a reciprocal Non-poaching responsibility confirming not employing, partnering, contracting or engaging each other’s employees, agents, consultants, advisers, independent contractors, partners, officers, directors or anyone otherwise having an interest in operation or management of the other and provides for a comprehensive solution to confirm compliance of the conditions agreed in the terms of the agreement.
If these employees subsequently join direct competitors, it can result in substantial economic loss for the ex-employer. A non-poaching agreement therefore enforces guidelines to be followed in cases of lateral hiring.
The Indian Contract Act, 1872: Sec - 27
Holds any agreement restraining an individual from exercising a lawful profession, trade or business of any kind to be void. The Act considers restraint to be reasonable if it affords fair protection to the parties and does not interfere wit public interest. NPAs have the potential of restraining the rights (employment opportunities) of an entity (the employee) that is not party to the contract between two other entities (the employers).
Due regard must be given to the fact that Indian courts have repeatedly held restrictive covenants post termination of employment contract to be in violation of the Act. They may be held valid only in certain cases, but it is still a contentious matter.
In the above circumstances it would be better you take wise decision to avoid legal hassle due to this.
