Purpose The purpose of this paper is to examine the relationship between corporate social responsibility (CSR) and employees’ affective commitment. Three underlying mechanisms are used to explain the relationship between CSR and commitment, namely, deontic justice, social identity theory and social exchange theory. Design/methodology/approach Data were collected through survey questionnaires. The sample consisted of 161 employees who work in private and public organizations in Tunisia. Regression analysis was conducted using a multiple mediation model. Findings The results reveal a positive and significant relationship between CSR and employees’ affective commitment. The perception of person–organization fit, organizational identification and perceived organizational support mediates the relationship between CSR and affective commitment. Originality/value With regard to CSR, past studies have never deal with deontic values in analyzing work behaviors. Furthermore, most previous studies have considered a direct effect between CSR perceptions and affective commitment. This study extends the literature by conceptualizing the indirect mechanisms linking CSR to employees’ affective commitment.

Purpose Prior research has conceptualized perceived organizational support (POS) as a stable variable over time varying from one individual to another. Nevertheless, it can be assumed that POS fluctuates within the same person over the course of several weeks due to different experiences lived at work. The authors suggested in the present study that weekly POS is predictive of employees’ weekly subjective well-being at work (i.e. increased positive affect toward the organization, and decreased negative affect toward the organization and psychological strains at work). In addition, the purpose of this paper is to examine the mediating role played by weekly work engagement in these relationships. Design/methodology/approach In total, 20 employees completed a first general questionnaire and then completed an online questionnaire during 12 consecutive weeks. Findings Results of hierarchical linear models indicated that weekly POS positively predicts weekly employees’ work engagement which, in turn, positively predicts weekly employees’ well-being (i.e. increasing positive affect toward the organization and decreasing negative affect toward the organization and psychological strains at work). Research limitations/implications Overall, these findings contribute to the POS and work engagement literatures. It shows that POS fluctuates within person over the course of several weeks and is a predictor of weekly employees’ well-being through its effects on weekly work engagement. Originality/value To the authors’ knowledge, this is the first study to examine within-person weekly variations in POS as a predictor of employees’ weekly work engagement and its subsequent consequences.

This paper provides an empirical examination of the effects of co-workers' procedural justice, defined as the individual's perception of how procedural justice is displayed towards him/her by the group. Drawing on the social exchange literature, it is confirmed that team affective commitment mediates the relationship between team voice -a form of co-workers' procedural justice -and team citizenship behaviors. The study also tests whether this positive indirect effect is moderated by neuroticism and intrinsic motivation.The results from a survey of 154 dyads consisting of employees and their current supervisor generally support the hypotheses. Team voice is a strong and consistent predictor of team citizenship behaviors, and the effect is mediated by team affective commitment only when intrinsic motivation is low and/or neuroticism is low. This study extends knowledge of the different sources of justice. Specifically, it shows that team voice and the boundary conditions of its effects are crucial to understanding attitudes and behaviors directed towards the team. This finding highlights the necessity of carefully taking into account the ability to express one's opinion inside teams.
