Ergonomics is an important workplace practice. Experienced stress in the workplace manifests itself in poor physical and mental health, and is associated with numerous negative personal and organizational outcomes. This study examines ergonomics and ergonomic training and their potential to reduce dysfunctional personal and work outcomes; specifically, job induced-tension and job dissatisfaction directly and through perceptions of person–environment fit and perceptions of control. Quantitative and qualitative findings indicate positive relationships between ergonomic design and ergonomic training with perceptions of person–environment fit and control. Person–environment fit and control fully mediated the relationship between training satisfaction (component of ergonomic training) and job dissatisfaction, while partially mediating the relationship between work-area design (a component of ergonomic design) and job-induced tension.
