RESUMO
Esta pesquisa objetivou analisar o poder mediacional do comprometimento organizacional afetivo na relação entre as percepções de justiça distributiva, processual e interacional e o burnout. Participaram da pesquisa 233 professores universitários. Foram aplicados os instrumentos avaliativos Maslach Burnout Inventory, Escala de Percepção de Justiça Organizacional e Organizational Commitment Questionnaire. Analisou-se o poder mediacional do comprometimento na relação entre a percepção de justiça e o burnout, a partir da regressão hierárquica. O poder mediacional do comprometimento se confirmou na relação entre percepção de justiça distributiva e exaustão. Concluiu-se que a percepção de injustiça na forma de distribuição de recursos pode levar o professor universitário à exaustão, o que pode ter probabilidade aumentada diante da falta de comprometimento.
This study aimed to analyze the mediational power of the affective organizational commitment in the relation among the perceptions of distributive, procedural, and interactional justice and burnout. Participants were 233 university professors. The following instruments were used: Maslach Burnout Inventory, Organizational Justice Perception Scale, and Organizational Commitment Questionnaire. We analyzed the mediational power of commitment in the relation between perception of justice and burnout, from a hierarchical regression. The mediational power of commitment was confirmed in the relationship between the perceptions of distributive justice and exhaustion. It can be concluded that the perceptions of injustice in the form of resource distribution may lead university professors to exhaustion, which might be more likely to happen if there is lack of commitment.
