Longitudinal associations between the rates of change in family to work enrichment, leader-member exchange, and job satisfaction

By integrating the work-home resource model with the leader-member exchange (LMX) theory, we adopt a change perspective to examine the effects of the change rate in family-to-work enrichment (FWE) on that in job satisfaction through the change rate in LMX. Using a longitudinal, multilevel sample of 360 employees in 71 teams, the results of three waves of data over eight months reveal the FWE change rate is associated positively with the LMX change rate, which, in turn, is associated positively with the job satisfaction change rate. Furthermore, we show that LMX differentiation at Time 1 moderates the FWE change rate's effect on the LMX change rate over time, such that the relation is stronger when the LMX differentiation is high at Time 1. Moreover, the LMX change rate mediates the interactive effects of the FWE change rate and Time 1 LMX differentiation on the job satisfaction change rate over time. The results also show that the initial level of FWE is related positively with the LMX change rate, but not with the job satisfaction change rate. These findings emphasize the importance of studying changes in family-work research and providing new insights into the processes of the FWE change rate's effects on the change rates of important work outcomes over time.
