Does political self-disclosure in social media hamper tacit knowledge sharing in the workplace?

Purpose The purpose of this is to explore recipients’ reactions to co-workers’ political self-disclosure on social media and their willingness to share tacit knowledge with the disclosers. The paper aims to understand whether political self-disclosure with dissimilar value and negative valence hampers tacit knowledge sharing among co-workers in a workplace setting. Design/methodology/approach This study applies an online survey combined with the experimental vignette methodology approach to collect respondent data. Further, the study uses the partial least squares-structural equation modelling method to analyse the 144 collected responses. Findings This study suggests that perceived content negativity towards co-workers’ political self-disclosure has a weak and significant indirect effect on recipients’ willingness to share tacit knowledge, and that perceived value dissimilarity has an insignificant indirect effect on recipients’ willingness to share tacit knowledge. Research limitations/implications This study is a cross-sectional research that was conducted at a public organisation, with a limited number of samples and non-probabilistic sampling method. Thus, the results of this study may be subject to bias, and the generalizability of the findings should be taken into consideration. Practical implications Although this study shows that political self-disclosure does not likely affect tacit knowledge sharing, senior management of an organisation is encouraged to educate their employees about the potential consequences of self-political disclosure embedded in information employees post in social media. The posted information may attract positive or negative perceptions from the recipient to the discloser. Therefore employees are expected to use social media properly and minimise the possibility of posting something that might trigger a negative perception or emotion from their co-workers. Originality/value Sharing topics related to political self-disclosure on social media potentially hampers tacit knowledge sharing in organisations and is relatively rare in the knowledge management literature. In particular, the existing literature bases its studies on private sector organisations. Furthermore, the empirical evidence of this study is based on an Indonesian public sector organisation, which is also relatively rare in the literature.
