PurposeWork-related use of information and communication technologies (ICTs) after hours can be potentially detrimental to employee well-being. In the current study, we examine whether psychological detachment mediates the link between work-related use of ICTs after hours and fatigue and whether affective commitment exacerbates this mediated relationship.Design/methodology/approachWe collected two waves of data from 295 employees in Vietnam, with 51% being female and an average age of 37.81 years old (SD = 7.93).FindingsWork-related use of ICTs after hours was positively related to employees' fatigue via psychological detachment. The negative relationship between work-related use of ICTs after hours and psychological detachment was stronger for employees with higher affective commitment.Practical implicationsOrganizations are encouraged to set policies and procedures to reduce work-related use of ICTs after hours to protect employee health; when work-related use of ICTs after hours is necessary, organizations should provide employees, especially those with higher affective commitment, with resources and strategies to better detach from this experience.Originality/valueOur findings contribute to the understanding of how work-related use of ICTs after hours might adversely affect employee well-being through psychological detachment and that more committed employees can be more affected in this process.

PurposeThe support of host country nationals (HCNs) is a key determinant of expatriate adjustment and performance. The purpose of this paper is to explore underlying motivations for their support to expatriates. Previous research has shown that HCNs with pro-social motivation are more likely to help expatriates. Drawing upon motivated information processing in groups (MIP-G) theory, the authors test whether epistemic motivation moderates the observed relationship between pro-social motivation and HCNs’ support toward expatriates.Design/methodology/approachThe authors ran two correlational studies (N = 267) in the USA (Study 1) and South Korea (Study 2). Across two studies, epistemic motivation and social motivation were measured using their multiple proxies validated in previous research. The authors also measured HCNs’ willingness to offer role information and social support to a hypothetical expatriate worker.FindingsResults lend support to our hypotheses that pro-social HCNs are more willing than pro-self HCNs to provide role information and social support to the expatriates, but this occurs only when they have high rather than low epistemic motivation.Originality/valueThe current paper contributes the literature on HCNs helping expatriates by qualifying the prior results that a pro-social motivation (e.g. agreeableness and collectivism) increases the willingness of HCNs to help expatriates. As hypothesized, this study found that that case is only true when HCNs have high, rather than low, epistemic motivation. Also, previous research on MIP-G theory has mainly focused on the performance of small groups (e.g. negotiation, creativity and decision-making). To the best of the authors’ knowledge, this research is the first attempt to test MIP-G theory in the context of HCNs helping expatriates.
