Local Law 185 and Local Law 186 (both passed in 2018) require that employers provide employees with lactation accommodations, including a lactation room where employees can pump/express breast milk, and reasonable time to pump/express breast milk.
Employers are also required to have a written lactation policy that meets certain requirements under the law and must provide it to all new employees. The NYC Commission on Human Rights has developed several model lactation accommodation policies and a request form.
