This research examines whether the volunteers of a non-profit organisation report appraisal and autonomous respect, job satisfaction and intent to remain a volunteer with the organisation, when they perceive that the paid workers of the organisation display self-sacrifice on behalf of the organisation and interactional justice. The research had a cross sectional survey design and the participants were volunteers working with paid workers in a non-profit organisation (a hospice; N = 52 hospice volunteers). Multiple regression analyses were conducted to test the hypotheses about direct effects. Among volunteers, autonomous and appraisal respect were found positively and directly related to job satisfaction. Additionally, among volunteers, interactional justice received from the paid workers of the organisation was found positively and directly related to autonomous respect, appraisal respect, and job satisfaction. Furthermore, among volunteers, perceived self-sacrifice on behalf of the organisation by the paid workers of the organisation was found directly and positively related to appraisal respect. Thereafter, a mediation regression analysis was conducted to test the hypothesis about the indirect effect. The mediation regression analysis showed that among volunteers, interactional justice received from the paid workers of the organisation relates positively and indirectly to job satisfaction through appraisal respect as a mediator. The theoretical and practical implications, as well as the limitations and suggestions for further research, are discussed.Show less
