Employment Discrimination laws seek to prevent discrimination based on race, sex, religion, national origin, physical disability, and age by employers among other things. A growing body of law also seeks to prevent employment discrimination based on sexual orientation. Discriminatory practices include bias in hiring, promotion, job assignment, termination, compensation, retaliation, and various types of harassment. The main body of employment discrimination laws consists of federal and state statutes. The United States Constitution and some state constitutions provide additional protection when the employer is a governmental body or the government has taken significant steps to foster the discriminatory practice of the employer.
