Anti-discrimination law
The Civil Rights Act of 1964 was the first major development in anti-discrimination law in the US, though prior civil rights legislation (such as the Civil Rights Act of 1957) addressed some forms of discrimination, the Civil Rights Act of 1964 was much broader, providing protections for race, color, religion, sex, or national origin in the areas of voting, education, employment, and public accommodations. This landmark legislation led the way for other federal legislation, which expanded upon the protected classes and forms of discrimination prohibited under federal legislation, such as the Fair Housing Act or the Americans with Disabilities Act. These protections have also been expanded through the courts interpretation of these pieces of legislation. For example, the 7th and 2nd circuit courts have both ruled that employment discrimination based on sexual orientation is a violation of Title VII of the Civil Rights Act. In addition to federal legislation, there are numerous state and local laws that address discrimination that is not covered by these laws.
Harassment
Harassment, under the laws of the United States, is defined as any repeated or continuing un-consented contact that serves no useful purpose beyond creating alarm, annoyance, or emotional distress. In 1964, the United States Congress passed Title VII of the Civil Rights Act which prohibited discrimination at work on the basis of race, color, religion, national origin and sex. This later became the legal basis for early harassment law. The practice of developing workplace guidelines prohibiting harassment was pioneered in 1969, when the U.S. Department of Defense drafted a Human Goals Charter, establishing a policy of equal respect for both sexes. In "Meritor Savings Bank v. Vinson," : the U.S. Supreme Court recognized harassment suits against employers for promoting a sexually hostile work environment. In 2006, President George W. Bush signed a law which prohibited the transmission of annoying messages over the Internet ("aka" spamming) without disclosing the sender's true identity.
