The Great State of Texas Workforce commision actually has a nice outline of a Handbook and covers a lot but it fits our right to work state laws. They even warn you if some policies might be questioned at the federal level if misapplied.
I also had an employment lawyer write my employment agreement, application. It cost me a several hours of my time and 2K of the lawyers billing.
The employment lawyer handled the pre-screening questions/ background check and the no-raid. Did not even think of a non-compete but no raid is a good tool to keep people from stealing your employees and clients.
