Claims that an employer failed to accommodate adequately a new mother’s desire to pump breast milk on the job are not covered by either federal gender or disability discrimination laws, a federal judge in Manhattan ruled yesterday.

Joining a handful of other courts that have considered the question, Southern District Judge Lewis A. Kaplan dismissed a suit by Alicia Martinez, a cable television producer, who said her former employer, MSNBC Cable, failed in 1997 to provide her with a sufficiently private spot to pump breast milk during work breaks.
