Each day of National Small Business Week, the site will focus on a different topic related to running a small business, including financing and hiring. Today's topic? Regulations, including those related to Cobra requirements and payroll processing. You can also brush up on your knowledge of child labor laws. For example, the guide points out that it's illegal for a 16- or 17-year-old worker to clean a meat slicer or operate a nail gun. Up next? An in-depth guide to insurance.
