(CNN) - A former executive of Oprah Winfrey's network is suing for sex discrimination.
Carolyn Hommel claims she was replaced by a temporary employee at OWN after she was forced to take medical leave during her pregnancy.
In the complaint, Hommel claims she was hired in 2010 as senior director of scheduling and acquisitions. She says after taking medical leave, her duties were gradually taken away and that she was told she was being laid off a month after giving birth in 2012.
Hommel claims she was encouraged to apply for a vice president's job, but was passed over.
Neither Oprah nor OWN has commented on the lawsuit.
