Investigations of the causal relationship between organizational commitment
and job satisfaction have yielded contradictory findings. Little empirical
research has looked at this complex relationship in the context of work ef
fort. The purpose of this study was to determine how these variables intera
ct in the service environment. Using a sample of 425 employees in two servi
ce organizations, the author tested two structural equation models. The hyp
othesized model with organizational commitment as a moderator between job s
atisfaction and service effort fit better than a model with job satisfactio
n as moderator did. Conceptual implications are discussed, and suggestions
for Future research are made.
