A former female employee of Madonna (search)'s film company is suing the pop star and other executives of Maverick Films (search) on claims she was sexually harassed and wrongfully terminated.

Yael Oestreich (search) said in the Superior Court suit filed Wednesday that she was never given a promised salary increase by chief executive officer Mark Morgan and that he fired her in July without cause.

The suit said Maverick Films co-founder Guy Oseary and Madonna, both listed as defendants, "failed to conduct a reasonable investigation into defendant Morgan's background before hiring him and knew or should have known of his propensity for sexual harassment and discrimination."

Phone calls for Morgan, Oseary and a Madonna publicist seeking comment were not immediately returned early Thursday.

Oestreich, a former vice president of development at Maverick, said she was criticized by Morgan at a Nov. 11, 2003 social outing as being "uptight" for not joining in talks about sex. He also accused her of sleeping with three agents from United Talent Agency (search), her former employer, the suit said.

In the months that followed, the suit said, Oestreich was the target of "inappropriate sexual inquiries" and also accused of being insecure when she told managers of the alleged harassment.

The suit seeks general damages, medical expenses, loss of earnings and punitive and exemplary damages.
