Dear Ranjan,
The subject heading of your post is "HR Policies." You have used the singular noun "policy" and not the plural. Was this a grammatical mistake, or did you mean it figuratively?
To effectively handle employees in the company, you cannot rely on just one policy. You need to have a whole set of policies covering areas such as recruitment, training, promotion, performance, etc. Therefore, please clarify exactly what you need.
Earlier, I had provided a response to a similar post. You may click the following link to learn more about employee policies:
