Your employee handbook is not your policy and procedure manual. Nor do all businesses need a policy and procedure manual. For smart small business management; however, a good, clean employee handbook is necessary.
A policy and procedure manual is usually full of information on each policy your business has and what the policy or procedure is for each. It's more of a step-by-step guide of how to's in case employees have operational questions. It can also be more of a training guide that is updated from time to time or revised entirely.
An employee handbook, on the other hand, is usually not revised unless a new labor law results from a government agency or your company changes or updates a rule contained within the employee handbook.
