Click the "law" tab and enter keywords under advanced search. You are then able to check off which sources you would like to search including The United States Codes Annotated, The Code of Federal Regulations, The Federal Register and more.
The United States Codes Annotated includes statutes (laws passed by the state legislature or congress). Pay special attention to title 29 of the US Code which pertains to labor. You can also search statutes by selecting a specific state where statutes were passed.
The Code of Federal Regulations and The Federal Register include regulations (rules made by executive agencies).
Google Scholar allows you to search the Internet for legal decisions. This tutorial from the Wisconsin State Law Library shows you how to use this convenient and free tool. Keep in mind that using Google Scholar for legal research is not the same as using Westlaw, it is not comprehensive or necessarily up-to-date. It is a quick way to find legal cases, sometimes just a citation, which you can research further with Westlaw and other scholarly sources.
