In the current study framework, the authors test the underlying assumptions of affective events theory concerning the impact of job satisfaction and job insecurity driven by incivility on intrapreneurial behaviour.,Data were collected with a sample of 510 employees from five organisations. All hypotheses were tested via SmartPLS3. Additionally, a distinction between formative and reflective measures was performed.,Findings revealed that incivility decreases intrapreneurial behaviour, mediated by job satisfaction and job insecurity. Additionally, this study’s results show that the relationship between job satisfaction and job insecurity and intrapreneurial behaviour distinguishes unionised employees from employees who are not unionised.,The cross-sectional nature of the present data precluded definitive statements about causality. Additionally, further studies should increase the sample size and include an international perspective to ensure the overall generalisability of the results.,Practically, this study’s findings point to the need for organisational management to understand better underlying employees' perceptions and their antecedents and consequences.,The study results contribute to the literature by testing the core assumptions of affective events theory and by extending the affective events theory model, incorporating contextual influences on the relationship between attitudes and behaviours. The authors also show for the first time that incivility can be directly (compared to indirectly) linked to emotional-based responses, but not to those responses driven by cognitive appraisals. Thus, the study also contributes to the incivility literature and the understanding of various antecedents and consequences of incivility. Additionally, this study addressed the notion of formative versus reflective measurement models for the first time relating to incivility and intrapreneurial behaviour, allowing for more sensitive and less biased results. Herein lies an additional methodological contribution.
