Challenged by Great Expectations? Examining Cross-Level Moderations and Curvilinearity in the Public Sector Job Demands–Resources Model

Abstract

This article extends the job demands–resources model in the public sector by including (a) cross-level (moderation) effects of job demands and resources, (b) positive and nonlinear effects of job demands, and (c) vitality as a key work engagement concept. Data on expected contributions and developmental rewards in public university colleges (n = 65 teams and n = 219 employees) reveals that individual-level higher expected contributions are associated with higher performance, mediated by vitality. This mediation is stronger in the presence of more team-level developmental rewards, suggesting a cross-level moderated mediation. We find indications for curvilinear effects of expected contributions. Contrary to expectations, these effects do not show inverted U shapes, but rather exponential relations. Our results contribute to “bringing in a psychological perspective” in public administration and suggest that public leaders could apply the job demands–resources model as a practical tool and vitality as a metric to create healthy and effective work environments.

The Role of Feedback Quality and Organizational Cynicism for Affective Commitment Through Leader–Member Exchange

“…This can be interpreted as a worrying trend as research suggests that the increasing workload is unfortunate to organizational performance because it fosters intentions to quit one’s job and it lowers job satisfaction (Gould-Williams et al, 2014). This makes it important for HRM studies to increase our understanding of how public sector employees can be managed in a challenging work environment (Bauwens et al, 2019a; Steen & Schott, 2019).…”

Stressed out public servants? Testing the stress appraisal of psychological and emotional stressors on stress reactions through psychological capital

“…, 2020). Although many JD-R studies support this causality, future studies using longitudinal or experimental designs are needed to test the actual causality of these relationships (Bauwens et al , 2021). These experimental studies might also focus on the causality among the states of stress.…”

“Who Champions or Mentors Others”? The Role of Personal Resources in the Perceived Organizational Politics and Job Attitudes Relationship

“…This theory seeks to emphasize on the affective experiences (e.g., emotions and temperaments) that play a vital role in defining behaviors and attitudes (Miao et al, 2017 ). However, scholars have further explicated that significant resources within the means of employees will propel them to mitigate this issue (Abdullah et al, 2017 ; Bauwens and Decramer, 2019 ). This theory explains that the prevalence of adverse environments perceived by the workforce jeopardizes their positive performance and leads to more negative emotions such as anxiety and frustration (Tang et al, 2020 ).…”
