ATLANTA — According to a growing list of angry employees, CNN may as well stand for “Caucasian News Network.” <br /> <br />Last December, CNN was hit with a lawsuit that claims African-American employees in similar positions are paid less than white staff. <br /> <br />The lawsuit also alleges that African-Americans working for CNN and other Time Warner subsidiaries are denied promotions by a glass ceiling. What’s more, CNN’s glass walls keep African-American staff out of senior positions in powerful, revenue-generating departments. <br /> <br />Up to 175 current and former employees have requested to join the class action lawsuit, according to the Hollywood Reporter. <br /> <br />CNN’s parent company Time Warner has until April 14 to respond to a motion requesting to amend the original complaint to putative class action.
