Labor and employment law can be a complex area to research. Like other highly-regulated areas (e.g. tax), there are unique, persuasive sources of primary law such as policy statements, memoranda, manuals, and guidelines that a careful researcher should be aware of. There is also specialized terminology from various sub-specialties, like employment discrimination, unions, wage and hour issues, government contractors, and workplace safety.
We encourage you to consult a secondary source (like a treatise, encyclopedia, or research guide) if you are starting to research a new labor or employment issue.
Chapter 5 : Federal Labor and Employment Law includes sections on traditional labor relations, employment discrimination, wage & hour, OSHA, federal legislation, and state employment law..
