LINCOLN, Neb. (AP) _ Emergency workers from across Nebraska recalled traumatizing accident scenes when asking for a new level of workers' compensation coverage. During a legislative hearing on Monday at the Capitol, the emergency workers said they had difficulty recovering from seeing the aftermath of the fatal accidents. One of the men testifying said a co-worker responded to an accident where his wife had died. The bill (LB780) would allow first responders who get ``mental injuries'' or mental illnesses from extraordinary work conditions to get workers' compensation. Gov. Dave Heineman vetoed a similar bill two years ago. The city of Omaha, the Nebraska League of Municipalities and business groups oppose the bill.
