The United States Breastfeeding Committee has posted FAQ’s about the provisions in the new health care reform legislation for workplace support of breastfeeding mothers. They summarize the provision:

Section 4207 of the Patient Protection and Affordable Care Act (also known as Health Care Reform), states that employers shall provide breastfeeding employees with “reasonable break time” and a private, non-bathroom place to express breast milk during the workday, up until the child’s first birthday.

Employers are not required to pay for time spent expressing milk, and employers of less than 50 employees shall not be required to provide the breaks if doing so would cause “undue hardship” to their business.

Here’s the link. It includes answers to questions including what the law does (and doesn’t do), when it takes effect, why the law is necessary, and what employers will gain from providing breastfeeding support for their employees.
