I agree with Mr. Banerjee. Any restriction on employment in a bond or NDA is illegal and invalid. Restriction on joining a competitor is valid only for a limited period, and it also depends upon which type of business/industry you are in. That is actually a non-compete clause. It does not apply to employees.
In effect, the NDA you are designing has no value. Do you expect that an employee is going to sacrifice his career to work for you? Even new employees will refuse to join you and will instead go work for someone else.
Also, you will lose your honest/faithful employees who are working with you. They will think that the company/management does not trust them anymore, which will also spread a wrong message and create a wrong picture/image in the market.
Today, if it is very hard to find a good job, then it is also difficult to find the right candidate or good person/employee who matches the requirements of the company. In this scenario, or with such types of policies/restrictions, there is a chance of losing our honest/faithful employees. Moreover, one should think of introducing such policies where employees should feel comfortable at the workplace. For example, I have heard somewhere that there are companies that do not allow access to or reading of personal mail in the office. They have put some "FORTIGUARD" which does not allow you to go to any ads related to jobs or opportunities. My personal view is that this type of policy encourages more loss of good employees. If somebody wants to go, they will go anyway; you cannot stop them. But somebody who really wishes to work long-term and wants to make their career with the same company will even start thinking of going to some other opportunity.
Secondly, the only reason a fresher is willing to work for you is to gain experience so that he can do well in his career.
