Résumé : Impression management (IM) concerns can lead to significant psychological consequences, potentially engendering unethical behavior. Therefore, adopting the stressor–strain–outcome framework, this study explores the effects of IM concerns on unethical behavior through wellbeing, and whether IM on social media (i.e., Instagram) triggers fatigue and results in unethical behavior at work. The findings of two empirical studies (n = 480 and n = 299) in different settings (Kuwait and the UK) suggest that women experience higher effects from IM concerns compared with men in Kuwait, while no gender differences are found in the UK. The results also confirm that impression management on social media platforms triggers fatigue, in turn increasing unethical behavior at work. This study contributes to the IM literature by capturing the effect of Instagram activities on workplace behavior.

Résumé : Although justice perceptions have been proven to be a critical determinant of readiness for change (RFC), research is still needed to investigate which source(s) of justice fosters employee's preparedness to face change within his/her organization. The aim of this study is to examine the simultaneous influence of three sources of justice, namely the organization, the supervisor and the coworkers, on RFC through perceived organizational support, perceived supervisor support and perceived coworker support, respectively.

Résumé : Along with the rapid growth of Chinese investments in France in recent years, there’s an increasing interest in studying the impact of Sino-Franco buyer–supplier relationship on their supply chain collaboration (SCC). We refer to both operational research and social management research to consider how does guanxi influence SCC and buying companies’ supply chain performance. By analysing the survey data collected from Chinese buyers in France, our findings have not only empirically proved guanxi’s importance in Sino-Franco relationship, but also revealed guanxi’s indirect influence on supply chain performance through the mediating effect of three different SCC dimensions (i.e. version sharing, resource-based collaboration and process-based collaboration).

Résumé : The purpose of this paper is to investigate the mechanisms and the conditions under which experiencing organizational justice fosters employees’ readiness for change. First, this study tests the mediating role of perceived organizational support between overall justice and readiness for change. Second, it examines whether perceived organizational competence moderates this indirect positive effect.

Résumé : Corporate Social Responsibility (CSR) has mainly been studied at a macro level through its impact on the financial performance of the company. However, individuals’ perceptions of CSR influence various attitudes and behaviors at work, including employees’ affective commitment. Whereas the relationship between perceptions of CSR and employees’ affective commitment has already been shown in the literature, less is known about its underlying mechanisms. This research seeks to specifically explain this relationship in order to understand how perceptions of CSR influence individuals’ affective commitment at work. We present two studies (Study 1, N = 181; Study 2, N = 145) to test a theoretical model that introduces person-organization fit (PO fit) as a mediator of this relationship and the need to belong as a moderator of the relationship between CSR and PO fit. The results of the moderated mediation model (using PLS-SEM) are developed and a discussion is provided.

Résumé : In this research, we examine the effect of workgroup interpersonal justice (WIJ) (defined as the extent to which employees are treated with dignity and respect by their co-workers) on innovative work behaviours (IWB). Specifically, we first test the mediating role of group identification (GI) in this relationship. Next, we examine the moderating role of reflexivity of the group on this mediation effect. Based on 204 employees, our results showed that the indirect effect of the WIJ on IWB, through GI, is moderated by the reflexivity of the group. Theoretical and practical implications are discussed.
