Although flexible working practices (FWPs) have been associated with positive individual outcomes, less is known about ‘how’ and ‘why’ such associations occur. Drawing on Conservation of Resources theory, this study examines the mediating and moderating processes which underpin the relationship between FWPs and job-related anxiety. The study’s hypotheses, proposing a moderated mediation model, are tested using data from Britain’s Workplace Employment Relations Survey (WERS) 2011. The results of generalised multilevel structural equation modelling (GMSEM) reveal that FWPs increase trust in management (TIM), which, in turn, decreases job-related anxiety. Furthermore, job autonomy moderates both the positive relationship between FWPs and TIM and the indirect relationship between FWPs and job anxiety through TIM, such that the mediated relationship becomes stronger when perceived autonomy is high. Our study encourages focusing on FWPs, as these stimulate perceptions of resource gain spiral, and the integrated influence of resources accumulated through such positive gain spirals promotes well-being.

尽管灵活的工作习惯（FWP）与积极的个人成果相关联，但人们对这种关联的“如何”和“为什么”发生的知之甚少。借助资源节约理论，本研究考察了FWP与工作相关焦虑之间关系的中介和调节过程。该研究的假设提出了一个适度的调解模型，并使用了英国《工作场所雇佣关系调查》（WERS）2011的数据进行了检验。广义多层结构方程模型（GMSEM）的结果表明，FWP增加了对管理的信任（TIM）。反过来，减少与工作相关的焦虑感。此外，工作自主权既减轻了FWP与TIM之间的正向关系，也减轻了FTIM与TIM之间的工作焦虑之间的间接关系，这样，当感知的自主性很高时，中介关系就会变得更牢固。我们的研究鼓励关注FWP，因为它们激发了人们对资源增益螺旋的认识，并且通过这种正增益螺旋积累的资源的综合影响促进了幸福感。
