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.

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.
