The Affordable Care Act (ACA) gives working mothers rights so they can pump milk and breastfeed their children. These rights went into effect in 2010. Unfortunately, many employers behave as if these rights do not exist. In addition, the law lacks teeth; there is not much in the way of enforcement at this time. The growing numbers of working mothers filing suit against their employers may, with any luck, have an effect upon how nursing mothers are treated at work.
