Name of Employee Personnel Policy

Should what we think of as the personnel policy be called Employee Handbook or Personnel Policy?

Sometime in the past, legal counsel advised a library system I was involved in, that the term "Employee Handbook" is correct. The document under now review at my library has what amounts to the rules of employment - typical sections about what the library provides, what we expect the employee to do etc. and does have a page acknowledging receipt of the document.

So what should it be called?

Thank you!
