Dear Chhavi Bhatnagar,
Organisations always expect their employees to grow their knowledge base. They encourage their employees to undertake the training courses relevant to their field. A few companies recommend their employees for the courses. Nevertheless, there is always a risk of the employee learning at the expense of the organisation and then quitting the company. In such a scenario, the organisation loses the funds spent on educating the employee.
Probably to tide over such a situation, you wish to enter into an agreement with the employee, that should the employee quit in a certain period, the amount spent is recoverable.
However, my suggestion is to make an agreement not for recovery but for the payment. Let the employee do a certain course at his/her expense. However, he/she becomes eligible to claim the amount spent on his education/training only if he/she stays for 'X' months/years. If the employee quits within the agreed period, then he/she forfeits the claim. I feel that this arrangement will be better.
In fact, I recommend going beyond tying the refund to the employee's stay
Let the employee do certain courses or training. Upon completion of the course, let the employee implement the learning at his/her workplace. After a period of six months or a year, let the employee prove to the company what cost he/she could reduce. If the employee has incontrovertible proof, then he/she becomes eligible not just for the refund of the fees spent on the course but also some per cent of the cost-saving he/she has done.
If the second formula that I have proposed works well, then it will foster a culture of learning but also cost-consciousness in the company. Others may get motivated and they also could follow suit.
All the best!
