Augmentative versus compensatory? How context shapes the impacts of general socializing on newcomer engagement

Newcomer relationship-building behaviors are usually considered beneficial. However, after closer inspection of past studies, the results were mixed. In this paper, we start to unpack these mixed effects by focusing on newcomer general socializing (i.e., building social connections by attending workplace events). Specifically, we investigate when newcomer general socializing is more or less beneficial for newcomer engagement by proposing two contrasting views: (1) applying conservation of resources theory, we argue general socializing increases engagement under high serial tactics, providing an augmentative effect; (2) utilizing attachment theory, we argue general socializing enhances engagement under low serial tactics, enabling a compensatory effect. Unexpectedly, neither an augmentative nor a compensatory effect was supported in Study 1 (China). To explain these results, we extend our investigation by including task interdependence as a boundary condition and test our predictions in Study 2 (Australia). The results of Study 2 support the compensatory effect: When newcomers experience low serial tactics under low task interdependence, general socializing enhances emotional engagement. However, general socializing is detrimental to cognitive engagement when newcomers experience high serial tactics under low task interdependence. Our research contributes to theory and provides insights to HR on how to tailor onboarding interventions to optimize newcomer engagement.
