Learn about employment laws. If you plan to hire employees or contract workers as part of your home based business, you will need to know how to navigate labor laws. These include, but are not limited to, minimum wage, overtime pay, required benefits, and other fair compensation regulations. It's best to hire legal counsel to make sure that you do not run afoul of these regulations.
