Five New York City police officers have lodged a civil rights-based class-action EEOC charge against the New York City Police Department alleging that it has discriminated against them by refusing to give them proper break time and legally required safe and clean spaces for expressing breast milk.

The detailed, 26-page charge, filed with the EEOC last week, is a precursor that will lead to a federal class action being launched by the officers later this year, according to their attorney, Eric Sanders, unless the city settles the action during the EEOC stage. Sanders believes the charge represents the first class-action claim brought against the NYPD for alleged discrimination against nursing mothers.
