textabstractPurpose: Research findings are ambiguous regarding the effects of age on sustainable labour participation (SLP), defined as the extent to which people are able and willing to conduct their current and future work. The purpose of this paper is to contribute by examining age effects on SLP by focusing on the moderating role of workload. Design/methodology/approach: A mixed-method study was conducted in 2018. First, a survey was distributed among a sample of 2,149 employees of the Dutch central government. Second, 12 interviews with public sector employees took place to gain greater insight into the quantitative data collected. Findings: Three components that reflect an employee’s SLP were studied: vitality, work ability and employability. The quantitative results, in general, showed that SLP decreased with ageing. However, in contrast to the hypothesis, the results showed a significant positive relationship between age and energy. Moreover, relationships between an employee’s age and certain aspects of their SLP were moderated by workload. The interviews helped to interpret these results. Practical implications: The findings demonstrate that some of the older worker stereotypes are unfounded, and the important practical implications of these are discussed. Originality/value: Earlier research has produced conflicting findings regarding the relationship between age and (aspects of) SLP. By investigating several aspects of SLP in separate regressions within this research, the specific influences of age have become clearer. Furthermore, the research provides fresh insights into the relationship between age and SLP by including moderating effects of workload.

年龄和可持续的劳动参与：研究调节作用

textabstract目的：关于年龄对可持续劳动参与（SLP）的影响的研究结果是模棱两可的，SLP定义为人们有能力并愿意从事当前和未来工作的程度。本文的目的是通过重点研究工作负载的调节作用来研究年龄对SLP的影响。设计/方法/方法：2018年进行了混合方法研究。首先，对荷兰中央政府的2149名员工进行了抽样调查。其次，对公共部门雇员进行了12次访谈，以更深入地了解所收集的定量数据。调查结果：研究了反映员工SLP的三个要素：活力，工作能力和就业能力。通常，定量结果表明，SLP随着年龄的增长而降低。然而，与假设相反，结果表明年龄和精力之间存在显着的正相关。此外，员工的年龄与其SLP某些方面之间的关系由工作量来调节。访谈有助于解释这些结果。实际意义：研究结果表明，一些老年工人的刻板印象是没有根据的，并讨论了其中的重要实际意义。原创性/价值：较早的研究在年龄和SLP（方面）之间的关系上产生了矛盾的发现。通过在本研究的不同回归中研究SLP的多个方面，年龄的具体影响变得更加清晰。此外，该研究还通过减轻工作量的影响为年龄和SLP之间的关系提供了新的见解。
