Federal employment law is codified in numerous sections of the U.S. Code over several titles. Besides the proprietary databases listed below, the U.S. Code is freely available at Cornell’s Legal Information Institute and GPO’s FDsys. Annotated versions of the code are available in the print USCA (fourth floor), in USCS (Lexis) and USCA (Westlaw).
Some administrative decisions, orders, and guidance are available in Bloomberg BNA Labor and Employment Resource Center, Bloomberg Law and Westlaw. They are also freely available at the website of agencies dealing with employment law. Those agencies include: the Employee Benefits Security Administration, the Equal Employment Opportunity, and the Occupational Safety and Health Administration.
