Chapter 151B

Massachusetts Chapter 151B is the state's primary anti-discrimination statute, prohibiting employment discrimination based on race, color, religious creed, national origin, sex, gender identity, sexual orientation, genetic information, ancestry, age (40+), disability, military service, criminal record (with limitations), pregnancy, and reproductive health decisions. The Act covers employers with six or more employees and complaints must be filed within 300 days with the Massachusetts Commission Against Discrimination (MCAD). Massachusetts has been a leader in expanding employment protections, including early adoption of sexual orientation and gender identity protections.

It also prohibits employers from asking about salary history prior to making a job offer and provides a safe harbor for employers who conduct good-faith self-evaluations of pay practices.
