Beyond onboarding: social media, microlearning, and psychological safety in hybrid talent integration

Purpose This study aims to examine the effects of social media-based onboarding and microlearning practices on Role Clarity (RC), Sense of Belonging (SB), and employee performance in hybrid work environments, as well as the conditional role of Psychological Safety (PS) in these relationships. By focusing on the post-hire phase, this study extends the discourse on social media beyond talent acquisition into the critical domain of talent management and integration. Design/methodology/approach The research uses four annual waves (2020–2023) of employee survey data from IT and professional services businesses operating in OECD and European Union countries (N = 1,400). The measurement structure is evaluated using Exploratory Factor Analysis/Confirmatory Factor Analysis, and hypotheses are tested using regression-based mediation/moderation (conditional process) with bootstrap inference. In a second stage, firm-year panel models (N = 350 firms, 2020–2023) are estimated using firm and year fixed effects, along with cluster-robust standard errors, to corroborate the temporal robustness of the observed relationships. Findings The findings indicate that social media engagement and microlearning participation significantly increase RC (ß = 0.287 and ß = 0.253) and a SB (ß = 0.198), and that these two constructs have a positive and substantial effect on performance. While microlearning participation partially mediates the relationship between social media engagement and the outcome variables, PS emerges as a significant contextual variable that strengthens this chain. Findings indicate that the effects are particularly concentrated in teams with high digital engagement and a strong PS climate. Originality/value The study proposes an integrated model that links social media-enabled onboarding, microlearning, RC, belonging, and performance into a single pathway in hybrid work settings. By combining individual-level survey evidence with longitudinal firm-year fixed-effects corroboration, the study extends the social media discussion from recruitment to post-hire talent integration.
