United States labour law

United States labor law is a heterogeneous collection of state and federal laws. Federal law not only sets the standards that govern workers' rights to organize in the private sector, but overrides most state and local laws that attempt to regulate this area. Federal law also provides more limited rights for employees of the federal government. These federal laws do not, on the other hand, apply to employees of state and local governments, agricultural workers or domestic employees; any statutory protections those workers have derive from state law.

The pattern is even more mixed in the area of wages and working conditions. Federal law establishes minimum wages and overtime rights for most workers in the private and public sectors; state and local laws may provide more expansive rights, Similarly, federal law provides minimum workplace safety standards, but allows the states to take over those responsibilities and to provide more stringent standards.

Finally, both federal and state laws protect workers from employment discrimination. In most areas these two bodies of law overlap; as an example, federal law permits state to enact their own statutes barring discrimination on the basis of race, gender, religion, national origin and age, so long as the state law does not provide less protections than federal law would. Federal law, on the other hand, preempts most state statutes that would bar employers from discriminating against employees to prevent them from obtaining pensions or other benefits or retaliating against them for asserting those rights.
