In the Indian context a policy covers different aspects.
A Contract / Agreement is the document that may retain an employee.
The Contract/ Agreement provides a clause by which the employee is required
to work with the company for certain number of years after undergoing training.
If the person wants to leave before the bond period is over, then he has to pay a previously agreed
sum as stated in the bond.

Repeat the process for ‘ Company policy for retaining employees’
or any other topic of your choice.
In my experience, more than professional development, it is important to also invest in personal development and in establishing emotional connect within the teams. This really helps in retaining employees better - and also creates a much happier work environment.
I would be happy to discuss this with you if you need.
