The objective of this study is to verify the relationships among organizational commitment, satisfaction and cooperation at work. The satisfaction is positioned as antecedent construct from the commitment dimensions and the cooperation as a behavioral consequent of this two constructs. The research method adopted was the survey using not probabilistic sampling by convenience. After literature review and hypothesis development, was collected 331 valid questionnaires, which were answered by employees from 8 organizations of the service sector in Curitiba (PR). The hypothesis were tested by a Structural Equation Model that presented good adjustment rates e revealed that satisfaction at work is a significant predictor of the variation of the three commitment dimensions, but with biggest influence over the affective and moral dimensions. Regarding to cooperation, the satisfaction doesn't exert statistically significant influence over the cooperative behavior. The others two dimensions of the commitment, affective and instrumental, don't exert any direct effect over cooperation, what stresses the primacy of the moral aspects and reciprocity norms over cooperative behavior.
