Hello Pooja,
If you are looking for READY-MADE or READY-TO-EAT stuff, frankly, 'forget it'.
Pl use the relevant key-words & you will get them. Also, you will need to tailor EACH of the policy to YOUR needs.
Here's one Link that I got by using the key-words: HR policies
https://www.citehr.com/138282-hr-policy.html
Many policy formats are in this thread.
The Link to the Search I did is:
HR policies
I wonder how you didn't get this ....!!!!!!!!!
Rgds,
