Employment discrimination law in the United States

Employment discrimination law in the United States derives from the common law, and is codified in numerous state and federal laws, particularly the Civil Rights Act 1964, as well as in the ordinances of counties and municipalities. These laws prohibit discrimination based on certain characteristics or protected categories. The United States Constitution also prohibits discrimination by federal and state governments against their public employees. Discrimination in the private sector is directly constrained by the Constitution, but has become subject to a growing body of federal and state law. Federal law prohibits discrimination in a number of areas, including recruiting, hiring, job evaluations, promotion policies, training, compensation and disciplinary action. State laws often extend protection to additional categories or employers.

Under Federal law, employers generally cannot discriminate against employees on the basis of:

The United States Constitution does not directly address employment discrimination, but its prohibitions on discrimination by the federal government have been held to protect federal government employees.

The Fifth and Fourteenth Amendments to the United States Constitution limit the power of the federal and state governments to discriminate. The Fifth Amendment has an explicit requirement that the federal government not deprive individuals of "life, liberty, or property", without due process of the law. It also contains an implicit guarantee that the Fourteenth Amendment explicitly prohibits states from violating an individual's rights of due process and equal protection. In the employment context, these Constitutional provisions would limit the right of the state and federal governments to discriminate in their employment practices by treating employees, former employees, or job applicants unequally because of membership in a group (such as a race or sex). Due process protection requires that government employees have a fair procedural process before they are terminated if the termination is related to a "liberty" (such as the right to free speech) or property interest. As both Due Process and Equal Protection Clauses are passive, the clause that empowers Congress to pass anti-discrimination bills (so they are not unconstitutional under Tenth Amendment) is Section 5 of Fourteenth Amendment.
