This Law Firm Publication by Fisher & Phillips LLP discusses Massachusetts's new transgender accommodations bill, recently signed into law by Governor Charlie Baker. The new law permits transgender employees to use the bathroom corresponding to their gender identity (rather than the biological sex assigned at their birth). The new law also protects transgender individuals from discrimination in places of public accommodation, and prohibits advertising that discriminates on the basis of gender identity. The new law goes into effect October 1, 2016, except the prohibition against discriminatory advertising, which is effective immediately.
