Requires the Department of Labor to address workplace violence in the health care and social service sectors. Specifically, Labor must promulgate an occupational safety and health standard that requires certain employers in the health care and social service sectors, as well as employers in sectors that conduct activities similar to the activities in the health care and social service sectors, to develop and implement a comprehensive plan for protecting health care workers, social service workers, and other personnel from workplace violence. In addition, those employers must investigate workplace violence incidents, risks, or hazards as soon as practicable; provide training and education to employees who may be exposed to workplace violence hazards and risks; meet record keeping requirements; and prohibit acts of discrimination or retaliation against employees for reporting workplace violence incidents, threats, or concerns.
