Background The healthcare service sector is confronting a global labor shortage. Despite this fact, health care professionals are still highly vulnerable to organizational injustice, which negatively influence organizational commitment, putting an additional burden on the health sector. Thus, this study aimed to investigate the correlation between organizational commitment and organizational justice among health care workers. Methods Facility-based cross-sectional study design was conducted among 395 health care professionals in the Jimma zone. Four Hospitals and 10 health centers were involved in the study randomly. The sample was distributed proportionally based on the number of health care workers. To select individuals, a systematic random sampling method was employed. Data were collected through self-report questionnaire using modified Alan and Mayer scale to measure organizational commitment and Niehoff and Moorman scale to measure organizational justice. The validity of the tools was checked using the reliability coefficient alpha and it was >0.7. The collected data were cleaned and entered into EpiData software version 3.1 and exported to SPSS version 20 for analysis. Descriptive and inferential statistics were done. Results This study revealed that 212 (53.7%) of the respondents scored a low level of organizational commitment. About half of the participants, 202 (52.2%), judged organizational justice were fair. All organizational justice dimensions showed a positive and significant correlation with all organizational commitment dimensions. Thus, the finding revealed that overall organizational commitment and organizational justice had a strong and positive correlation (r = 0.695**, P < 0.01). From the regression analysis distributive justice (B = 0.382, 95% CI: 0.31–0.45), and procedural justice (B = 0.17, 95% CI: 0.06–0.283) were among the factors affecting organizational commitment. Conclusion and Recommendation This study showed a strong link between organizational commitment and organizational justice. This suggests that organizational justice has been recognized as a motivator and factor influencing health care workers’ organizational commitment. As a result, enhancing organizational justice can help to maintain the commitment of healthcare workers and the facility’s capabilities.

Background Counterproductive behavior costs organizations and their members which will ultimately affect work-related outcomes and organizational success. Organizational justice has the potential to affect the level of counter productive behavior. However, there is a paucity of studies to show the link between counterproductive behavior and organizational justice dimensions in the Ethiopian health care system context. Therefore, the purpose of this research was to look into the link between organizational justice, and counterproductive work behavior among health care professionals. Methods The 395 study participants were chosen using a facility-based cross-sectional study methodology. A proportionate stratified systematic random sampling technique was deployed to select study participants from health facilities. Data was gathered using a structured self-report questionnaire by CWB Scale that was developed by Spector and Fox (2005) with Cronbach’s alpha of an average of (0.84–0.87). Data was obtained, cleaned, and entered by Epidata3.1. Finally, for descriptive and inferential statistical analysis, the data was exported to SPSS version 23.0. Results According to the findings, 159 (40.3%) of the study participants engaged in counterproductive job activities. Organizational justice was assumed to be fair by about half of the respondents, 202 (52.2%). Distributive Justice (=−0.141, p.05) was found to be a significant and negative predictor of counterproductive work behavior in the regression analysis. Age (β=−0.014, p< 0.05), the average number of hours worked every week (β=−0.009, p< 0.05), and experience (β=0.016, p< 0.05) were found to be significant predictors of the counterproductive work behaviors. Conclusion and Recommendation This study indicated that distributive justice show significant contribution in reduction of counterproductive work behaviour.As a result, improving organizational justice can aid to reduce counterproductive work behavior which in turn increases the facility’s productivity.
