Work-related Risk Factors for Workplace Violence among Korean Employees

Abstract

Objectives: The aim of this study was to identify work-related risk factors for workplace violence in a representative sample of Korean employees. Methods: We analyzed the associations between work-related factors and workplace violence in 29,171 employees using data from the 2011 Korean Working Conditions Survey. The survey included questions about verbal abuse, unwanted sexual attention, threats and behavior that humiliated the victim, physical violence, bullying/harassment and sexual harassment, and a respondent who answered yes to any of these 6 items was considered a victim of workplace violence. Results: The prevalences of verbal abuse, unwanted sexual attention and threats/ behavior that humiliated victims in the month preceding the study were 4.8, 1.0 and 1.5%, respectively. The prevalences of physical violence, bullying/harassment and sexual harassment in the year preceding the study were 0.7, 0.3 and 0.4%, respectively. Service workers had higher prevalences of overall workplace violence. Non-regular workers (OR=2.38, 95% CI=2.01–2.84), working more than 60 hours per week as opposed to 40–48 hours per week (OR=1.83, 95% CI=1.45–2.31) and night shift work (OR=1.88, 95% CI=1.54–2.30) were significant risk factors associated with workplace violence. Conclusions: Long working hours, job insecurity and night shift work were associated with a significant increase in workplace violence among Korean employees.(J Occup Health 2014; 56: 12–20)
