In this study, the problem question was raised whether corporate social responsibility (CSR) is/can be an effective tool against workplace mobbing and psychosocial stressors in organizations. Therefore, the purpose of the study is to determine the prevalence of workplace mobbing in Lithuanian and Polish organizations in order to compare in which organizations the manifestation of the phenomenon is the strongest and analyzing psychosocial stressors in parallel. To achieve the purpose, 823 employees of three types of organizations were surveyed. The respondents belonged to organizations that implement the principles of corporate social responsibility, organizations that intend to become socially responsible and organizations that do not implement corporate social responsibility and do not seek to become socially responsible. The empirical study was conducted using the questionnaire "Mobbing as a Psychosocial Stressor in the Organizations Accessing and Implementing Corporate Social Responsibility-MOB-CSR". This questionnaire is valid and reliable; the correlation relationships between subscales show interconnectedness and statistically reliable relationships. The research results were calculated using the chi-squared test and the linear regression model. Statistically reliable relationships were found between the prevalence of workplace mobbing, psychosocial work stressors and corporate social responsibility. The results of the study show that along with the weakening of variables of corporate social responsibility, the probability of workplace mobbing is increasing but CSR in itself does not ensure the prevention of workplace mobbing in the case of Lithuanian and Polish organizations. If the findings of the study are considered by the managers of organizations, this can affect both employees' quality of life towards improvement and more transparent/purposeful implementation of corporate social responsibility, i.e., responding to the true meaning of CSR.
