Socializing the newcomer: The mediating role of leader-member exchange

We expand organizational socialization research by integrating social exchange theory, specifically leader-member exchange (LMX), as an important mediator in explaining newcomer attachment to the job, occupation, and organization. Using temporally-lagged data from 213 newcomers across 12 telemarketing organizations, we found that newcomer perceptions of LMX mediate the association between supervisory socialization tactics (i.e. supervisory job-focused advice, guidance, and role modeling) and occupational identification as well as between supervisory socialization tactics and perceived person-organization fit - but not between supervisory socialization tactics and job satisfaction. Our study specifies (1) LMX as a compelling mediating mechanism within the new employee 'on-boarding' process and (2) the immediate supervisor as an important relational source for newcomer attitudes.
