The present study reports a broad perspective on work characteristics related to private security work and identified predictors of health impairments in a German-speaking sample (N = 683). Occupational conditions, exposure to violence/aggression, and psychosocial work characteristics each significantly explained incremental variance in psychosomatic complaints. Detailed findings revealed that average weekly working hours (and unusual working hours) substantially exceeded those of other service sector occupations (or the general population) in Germany. Exposure to violence/aggression was also substantial in regard to the European average. Participants reported low social status, promotion opportunities, and pay while their work offered substantial learning demands. Possibilities to acquire relevant skills, supervisor feedback, job control, or participation opportunities seem to provide little support at work. Excessive working hours, worries about violence, social status, and lone work emerged among the strongest predictors of psychosomatic complaints. Additionally, unusual working hours and job stressors (physical workload, quality impairments) increased the prevalence of psychosomatic complaints.
