Workplace Ethical Climate and Workers' Burnout: A Systematic Review.

Objective: Workplace ethics is a central theme in occupational health; an ethical climate aims to implement and uphold standards of integrity and fairness. Furthermore, the correlation between ethical climate and burnout has been highlighted in several studies, and the impact of a negative ethical climate in the workplace has been reported to affect workers' mental health and job performances, resulting in increased burnout incidence. The aim of this systematic review is to assess the relationship between ethical climate and burnout in the workplace.

Method: This review was conducted following the PRISMA statements. Three databases were screened, including research articles written in the English language during the last 10 years, investigating the relationship between burnout and ethics in the workplace. The quality of articles was assessed with the Newcastle-Ottawa Scale.

Results: 1153 records were found across three databases; after duplicate removal and screening for title and abstract, 46 manuscripts were screened by full text, resulting in 13 included studies. The majority of the included studies were performed on healthcare workers (n=7, 53.8%), and with a majority of female participants (n=9, 69.2%). Most of the included studies (n=9, 69.2%) evaluated the correlation between ethical climate and burnout, while the other four (n=4, 30.8%) evaluated ethical leadership. Four studies reported a positive correlation between ethics and work engagement. Two studies highlighted that an ethical workplace climate reduced turnover intention.

Conclusions: Ethical climate plays an important role in burnout mitigation in workers and in improving work engagement, thus helping to reduce turnover intentions. Since all of these variables have been reported to be present in clusters of workers, these aforementioned factors could impact entire workplace organizations and their improvement could lead to a better work environment overall, in addition to improving the single factors considered. Further studies are needed to investigate the role of ethical climate in the workplace.
