The purpose of this cross-sectional study was to identify individual and employment characteristics associated with reporting workplace violence to an employer and to assess the relationship between reporting and characteristics of the violent event. Current and former employees of a Midwest health care organization responded to a specially designed mailed questionnaire. The researchers also used secondary data from the employer. Of those who experienced physical and non-physical violence at work, 57% and 40%, respectively, reported the events to their employer. Most reports were oral (86%). Women experienced more adverse symptoms, and reported violence more often than men did. Multivariate analyses by type of reporting (to supervisors or human resources personnel) were conducted for non-physical violence. Reporting work-related violence among health care workers was low and most reports were oral. Reporting varied by gender of the victim, the perpetrator, and the level of violence experienced.
