Federal and state laws prohibit the discrimination of individuals because of their gender (including sexual harassment of any type), race, religion, national origin, disability, ethnicity, pregnancy, age and sexual orientation, which are "protected classes".
The law also prohibits discrimination where an individual is "regarded as" being a member of a protected class, even if they are not in fact a member of that class. If you feel that you have been discriminated against because of your status in a protect class or if you have been adversely treated because of a false belief that you are a member of a protected class, you may have a cause of action for discrimination.
Federal and state laws also provide recourse for individuals who are retaliated against for complaining about discrimination in the workplace - whether the discrimination was against them or another employee.
If you have complained to your employer about discrimination in the workplace and were thereafter reassigned, disciplined, suspended, terminated, had your hours and/or overtime reduced or eliminated or were otherwise adversely treated in the workplace, you may have a cause of action for retaliation.

The ADA also protects individuals who are subject to adverse treatment because they are "regarded as" having a disability.
Title VII, the Pregnancy Discrimination Act and § 1981 are federal laws that provide recourse to individuals who have been discriminated against on the basis of their classification in a protected class. If you belong to one of the above-listed protected classes of individuals, had satisfactory job performance and received adverse treatment, unwarranted disciplinary action, were reassigned, your duties and responsibilities were reassigned to another individual outside of your protected class, and/or you were terminated from your position under circumstances that give rise to an inference of discrimination, you may have a cause of action for discrimination.
