On April 1, 2018, the Pregnant Workers Fairness Act (the "Act") takes effect. https://malegislature.gov/Laws/SessionLaws/Acts/2017/Chapter54. The Act amends Massachusetts' anti-discrimination law, G.L. c. 151B, which applies to employers with six or more employees, to now include pregnancy and related conditions as protected categories. The Act requires employers to provide "reasonable accommodations" for pregnancy and related conditions, including breastfeeding and the need to express breast milk, so long as the accommodations do not cause the employer "undue hardship."
