How To Implement HR Policies In New Established Company

Hi all,
happy Diwali to all
I have been newly recruited as HR manager for a franchise branch of an Insurance company, where including all staff 20 people or more is required.
As i m new to this field, help to out to calculate how many new personnel is required?
Secondly, how and what to implement Hr policies to this type of organization.
What are the benefits can we provide to retain the employees for long run, as the labor turn over ratio is too high in this organization.
Help me out to design the structure?

Hi,
This refers to your posting. Since you would have HR background, you will appreciate that these things cant be shared just across the net. One need to understand the entire gamut of operations, structure etc.
I retired from L&T as Head of HR in one of its business units. I am now presently a freelance HR Consultant and Softskill Trainer. If yourself / your organisation is interested, you can get in touch with me at [Login to view] and i can formally help you in a proper way.
Best wishes
