A Deutsche Bank vice president filed a gender bias lawsuit accusing the German bank of denying her pay and promotions, and trying to demote her because she took maternity leave. Kelley Voelker, who works in New York in a hedge fund group, said she has never been promoted in her 13 years at Deutsche Bank despite being qualified to become a director...A Deutsche Bank spokesman said: 'We take these allegations very seriously and are currently reviewing the complaint.' In her complaint, Ms Voelker said she rejected her boss' urging that she take a 'reduced role' after her return from maternity leave in May 2010. Upon her return, she said, Deutsche Bank directed bigger accounts to a male colleague, slashed her bonus, and tried to demote her to a 'vague' marketing job. The bank retracted the demotion after her lawyers complained, she said. [also refers to Bloomberg, Goldman Sachs]
