Effective Sunday, April 1, a new law in Massachusetts expressly prohibits discrimination against employees who are pregnant or experiencing pre- and/or post-birth pregnancy related medical needs. Known as the Pregnant Workers Fairness Act, the law immediately requires employers to provide their employees with notice of the act in writing by April 1, 2018 – a requirement that can be met by distributing this Guidance by the Massachusetts Commission Against Discrimination (MCAD). Subsequent to April 1, employers will be required to provide employees with written notice on two additional occasions: new employees must receive notice at or before the start of their employment; and secondly, notice must be given within 10 days of an employee notifying the employer of a pregnancy or pregnancy-related condition. We found this guidance by DDIFO employment counsel, Morgan, Brown & Joy, to be particularly helpful as well.
