Which U.S. law requires covered employers to display notices explaining workers’ rights under federal labor laws?

The National Labor Relations Act requires covered U.S. employers to inform employees about their rights under federal labor law.

Enacted in 1935, the law protects employees who organize, join unions, bargain collectively, or act together about workplace conditions. The National Labor Relations Board administers most of these protections.

The law is often confused with the Fair Labor Standards Act, which governs federal minimum wages, overtime, and child labor. The National Labor Relations Act instead focuses mainly on collective action and labor-management relations.

Employers commonly communicate these rights through an official workplace poster. Coverage has exceptions, including many public-sector employees, agricultural workers, domestic workers, and employees of airlines and railroads covered by other systems.
