Massachusetts Law outlaws treating people unfairly based on the persons membership in a "protected class," such as your race, national origin, religion, disability, age, sexual orientation, or gender identity.
If you fee that you have been treated unfairly based on protected class, you may file a Complaint of Discrimination at the MCAD.
