Lita Olsson was 30 weeks pregnant when she was assaulted while on shift as a registered nurse in one of the state's busiest emergency departments. She's also been witness to horrendous assaults on colleagues. She's now turned her attention to preventing occupational violence and helping to make our hospitals and health services safer for staff, patients and visitors. Lita spoke with the Senate about her experiences and her new work as the clinical lead for the Queensland Occupational Violence Strategy Unit.
