A number of federal and state laws protect employees against on-the job discrimination. Title VII of Civil Rights Act of 1968 is the main law which protects workers from on-the-job discrimination. This act prohibits discriminating against employees based upon their race, ethnicity, religion or gender. Age Discrimination in Employment Acts (ADEAs) and Americans with Disabilities Acts (ADAs) provide protections to workers who are over 40.
Other laws such as Equal Pay Act & Family Medical Leave Act also offer further protections by ensuring equal pay regardless gender/race amongst other things while also guaranteeing job security during periods absence due unforeseen circumstances.
There are a number of government departments that enforce these laws. If you have experienced workplace discrimination, please contact the relevant office directly. You can do this by submitting a formal complaint or just letting your employer know about the issue. This will allow them to take appropriate action without disrupting daily operations.
