United States labor law
Since the Civil Rights Act of 1964, all employing entities and labor unions have a duty to treat employees equally, without discrimination based on "race, color, religion, sex, or national origin." There are separate rules for sex discrimination in pay under the Equal Pay Act of 1963. Additional groups with "protected status" were added by the Age Discrimination in Employment Act of 1967 and the Americans with Disabilities Act of 1990. There is no federal law banning all sexual orientation or identity discrimination, but 22 states had passed laws by 2016. These equality laws generally prevent discrimination in hiring, terms of employment, and make discharge because of a protected characteristic unlawful. There is no federal law against unjust discharge, and most states also have no law with full protection against wrongful termination of employment. Collective agreements made by labor unions and some individual contracts require people are only discharged for a "just cause". The Worker Adjustment and Retraining Notification Act of 1988 requires employing entities give 60 days notice if more than 50 or one third of the workforce may lose their jobs. Federal law has aimed to reach full employment through monetary policy and spending on infrastructure. Trade policy has attempted to put labor rights in international agreements, to ensure open markets in a global economy do not undermine fair and full employment.
Affirmative action in the United States
Affirmative action policies were developed to address long histories of discrimination faced by minorities and women, which reports suggest produced corresponding unfair advantages for whites and males. They first emerged from debates over non-discrimination policies in the 1940s and during the civil rights movement. These debates led to federal executive orders requiring non-discrimination in the employment policies of some government agencies and contractors in the 1940s and onward, and to Title VII of the Civil Rights Act of 1964 which prohibited racial discrimination in firms with over 25 employees. The first federal policy of race-conscious affirmative action was the Revised Philadelphia Plan, implemented in 1969, which required certain government contractors to set "goals and timetables" for integrating and diversifying their workforce. Similar policies emerged through a mix of voluntary practices and federal and state policies in employment and education. Affirmative action as a practice was partially upheld by the Supreme Court in "Grutter v. Bollinger "(2003), while the use of racial or gender quotas for college admissions was concurrently ruled unconstitutional by the Court in "Gratz v. Bollinger" (2003).
