A longitudinal assessment of the determinant relationship between employee commitments to the occupation and the organization

A review of the research literature suggested that occupational commitment may be an antecedent to employees' commitment to the organization. Although several studies have assessed the general relationship between occupational and organizational commitment, none have attempted to establish the causal priority between the two constructs. In the present study, occupational commitment was viewed as a causal antecedent to organizational commitment. Based on longitudinal data from 100 management information systems professionals, this view was supported through cross-lagged analysis. Further, we examined a longitudinal causal model of the turnover process in which occupational commitment was placed as an antecedent to organizational commitment. Structural equation analysis supported the fit of this model to the data. Implications of the findings are discussed.
