The effect of change in supervisor support and job control on change in vigor: Differential relationships for immigrant and native employees in Israel

Building on the premises of the conservation of resources theory, the aim of this study was to investigate long-term effects of job resources on vigor among native and immigrant employees in Israel. More specifically, we investigated the effects of baseline and change in job control and supervisor support on change in vigor levels, as well as the degree to which these effects differ among educated native and immigrant employees in Israel. We surveyed 235 white-collar Eastern European and Russian immigrants and 235 white-collar native Israelis matched on occupational and demographic characteristics at two points of measurement with a 30-month time lag. Latent change score modeling revealed that among both immigrants and natives, change in job control was related to change in vigor. Multiple group analyses further revealed that among immigrant employees only, baseline levels of supervisor support were associated with change in vigor. In conclusion, these findings suggest that the utilization of resources as a means of acquiring new resources may be influenced by immigrant background. Managerial implications are discussed.
