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.

► Socialization theory myopically focuses on learning, ignoring social exchange.
► LMX is a compelling mediator within the newcomer adjustment process.
► Supervisory guidance and support increases newcomer LMX and work-related attitudes.
