Problem: Young workers, typically characterized as 15-24 years of age, are commonly employed in jobs where the risk of workplace violence is high. It is unknown how these young workers, at varying stages of development, might understand and respond to workplace violence differently. We set out to explore whether the experiences and understandings of young workers varied between those in middle (ages 15-17) and late (ages 18-24) adolescence. Method: Separate focus groups were conducted with working students (n = 31), ages 15-17 and ages 18-24, who had either experienced or witnessed workplace violence. A focus group guide was used to facilitate the sessions which were recorded, transcribed, and content analyzed for themes. Results: Those in the older group experienced more severe episodes of sexual harassment and physical assault, reported using formal mechanisms for reporting, and noticed an employer focus on customer satisfaction over employee safety, while the younger participants tended to report to their parents. Both groups reported negative effects of experiencing workplace violence including depression, anxiety, feelings of worthlessness, and spill over into personal life. Discussion: Findings suggest that young workers at different developmental stages may experience and respond to workplace violence differently. Further research is needed to see if these results are generalizable. Summary: It is imperative that we understand the distinct differences between these subsets of young workers and how they experience and respond to workplace violence in order to improve research, policy development, and prevention/intervention mechanisms.
