A New Jersey woman who had twins by a gestational surrogate has filed a discrimination suit against Verizon Communications because she was not allowed to take time off under the company's paid maternity leave policy.

Marybeth Walz of Red Bank said Verizon grants six to eight weeks of paid leave to women employees who become mothers through birth or adoption. Walz opted to use a surrogate because her uterus had been removed after she was diagnosed with cervical cancer in 2001. But the company refused to grant her paid leave, and instead required her to use vacation and sick days when the twins were born prematurely in November 2013, the suit said. As such, she suffers from a pregnancy-related disability because she is unable to become pregnant, her suit claims.
