(1) Background: Various investigations have confirmed that burnout prevails in intensive and demanding contemporary working environments. Most of these studies have analyzed the associations between emotional exhaustion and various work factors. We studied the gap in the literature by simultaneously considering the three commonly recognized dimensions of burnout (emotional exhaustion, depersonalization, and reduced personal accomplishment) using a representative sample of telecommunication sales managers. (2) Methods: 849 survey respondents completed an anonymous questionnaire that included items representing psychosocial factors at work, lifestyle characteristics, and the Maslach Burnout inventory. The hierarchical regression analysis revealed the predictors of emotional exhaustion, depersonalization, and reduced personal accomplishment. (3) Results: job demands and witnessing bullying at the workplace were the most powerful predictors of emotional exhaustion, followed by self-rated health, night work, education, and physical inactivity. Witnessing bullying at the workplace, job control, self-rated health, and physical inactivity were the strongest predictors of depersonalization. Finally, direct experiences of negative acts at the workplace, job control, social support at work, bullying exposure duration, family crises, physical inactivity, smoking and alcohol, and body mass index were the most important predictors of reduced personal accomplishments. (4) Conclusions: the present study fills a gap in the research surrounding the three dimensions of burnout. The findings not only confirm that high job demands, low job control, and low social support at work contribute to burnout but also contribute to the novel understanding that workplace bullying plays an integral role.
