Work-related extended availability (WREA) refers to employees being available for work-related matters during leisure time. Although studies have suggested negative effects of WREA on employee health, there is a scarcity of longitudinal research especially studies trying to disentangle how WREA may impact health. Moreover, there are only few studies dealing with interindividual differences in the effects of WREA on health. These aspects are crucial as they can help laying a foundation for interventions that help coming to terms with negative effects of WREA. The current study implemented a cross-lagged panel design with three waves to clarify how effects of WREA unfold and whether there are interindividual differences. Based on the stressor-detachment-model and person-environmental-fit theory, we proposed that (1) the relationship between WREA and sleep as well as between WREA and exhaustion is mediated by psychological detachment, and (2) that the relationship between WREA and the outcomes is moderated by segmentation preferences. In total, 528 employees (320 women, mean age = 48 years) participated in the study. Although there was a cross-lagged negative association between WREA and detachment, we did not find an indirect relationship between WREA and either sleep or exhaustion via detachment. Moreover, we did not find evidence for interindividual differences in the effects of WREA on any of the outcomes. On the basis of the negative cross-lagged relationship between WREA and detachment from work, we recommend organizations to discourage employees from WREA, because failure to regularly recover from work may lead to health issues in the long run.

Work-related extended availability (WREA; the availability of employees for work-related matters in their leisure time) seems to be associated with decreases in well-being and life-domain balance, but to date there is no quantitative synthesis of the scattered evidence. We conducted a random-effects meta-analysis (113 articles with 121 studies relying on k = 117 independent samples with N = 131,872) on the associations between WREA and employee outcomes while examining potential moderators as well as differences between availability demands and behaviors. WREA was adversely associated with recuperation, well-being and private life, but favorably with some work-related criteria. There were no systematic differences in effect sizes between availability demands and behaviors; however, segmentation preferences were a moderator. Overall, these results suggest that WREA may pose a threat to employee recuperation, well-being and private lives, especially when employees prefer separating work and private life. However, positive potentials of WREA should not be overlooked. Plain Language Summary Work-related extended availability (WREA) refers to the availability of employees for work-related matters in their leisure time. Studies have shown that WREA may go along with primarily negative consequences for employees, but to date, there is no comprehensive overview of the literature statistically summarizing the current state of research, which was done in the study at hand. We assumed that WREA be related to problems with recovery, poorer well-being and difficulties to find a balance between work and private life. We also assessed in how far WREA goes along with attitudes towards work, absence from work and the intention to change jobs. Moreover, we considered differences between demands to be available and behaviors of actually taking care of work-related matters during leisure time. Finally, we investigated factors that may be associated with stronger consequences of WREA. We included 113 scientific papers with a total of 131,872 participants. WREA was related to problems with recovery, poorer well-being and difficulties to find a balance between work and private life, but also to more positive attitudes towards work. We did not find systematic differences between demands to be available and availability behaviors. However, we found that the relationship between WREA and work creating conflict with family life were stronger in samples with higher preferences to segment work and private life. Our findings suggest that WREA may pose a threat to employee recuperation, well-being and private lives, especially when employees prefer separating life domains. Still, positive potentials of WREA should not be overlooked.

Zusammenfassung. Das Arbeitszufriedenheitsmodell von Bruggemann (1974) unterscheidet qualitative Arbeitszufriedenheitsformen (AZ-Formen), die sich auf das Befinden bei der Arbeit auswirken. Obwohl diese AZ-Formen auf individuellen Verarbeitungsprozessen basieren, wurden deren personenbezogene Einflussfaktoren bisher nur selten untersucht. Die vorliegende Arbeit überprüft diesbezüglich den Einfluss der individuellen Resilienz auf die AZ-Formen und untersucht deren Auswirkungen auf das Befinden bei der Arbeit. Hierzu wurden drei Studien mit insgesamt 477 Beschäftigten in drei Unternehmen durchgeführt. Außer den AZ-Formen wurden in diesen Studien die Arbeitsbelastung, personale Ressourcen der Resilienz (Selbstwirksamkeit, Optimismus und Achtsamkeit), resilientes Verhalten bei der Arbeit, Arbeitsengagement und psychische Befindensbeeinträchtigungen erfasst. Die Ergebnisse verdeutlichen die Bedeutsamkeit der Resilienz für die qualitative Form der Arbeitszufriedenheit und bieten Ansatzpunkte, wie AZ-Formen, die mit Befindensbeeinträchtigungen einhergehen, begegnet werden kann.
