Four women who worked for Houston-based Halliburton Co.'s former subsidiary Kellogg Brown & Root have filed federal lawsuits against the companies, claiming they endured sexual harassment and, in two cases, rape while working in Iraq... KBR would not comment specifically on the cases, but spokeswoman Heather Browne said all KBR employees are briefed on the company's code of business conduct, which "strictly prohibits sexual harassment by KBR employees," before being deployed to Iraq. Halliburton spokeswoman Cathy Mann said her company "is improperly named" in the lawsuits.
