While academic jobs generally provide a good degree of flexibility, academics also tend to work extra hours which can then lead to a poorer work-life balance. In this study, we compare academic vs. non-academic staff and anticipate that academics will generally report a poorer Quality of Working Life, a broad conceptualization of the overall work experience of employees. Secondly, we investigate whether the negative relationships between being an academic and Quality of Working Life variables are made worse by working extra hours, and moderated by the perception of having a balanced work-life interface. Our sample consisted of 1474 academic and 1953 non-academic staff working for nine Higher Education Institutions (HEIs) in the United Kingdom (UK). Data were analyzed via structural equation modelling. Results showed that academics tend to report a poorer Quality of Working Life than non-academics within HEIs, and this is exacerbated by their higher reported number of extra hours worked per week. The work-life balance of employees was found to moderate the negative relationships between academics (vs. non-academics) in variables such as perceived working conditions and employee commitment. We additionally found curvilinear relationships where employees who worked up to 10 extra hours were more satisfied with their job and career and had more control at work than those who either did not work extra hours or worked for a higher number of extra hours. These results extend previous research and provide new insights on work-life balance among academics and non-academics, which in turn may be relevant for the wellbeing practices of HEIs and wider HE policy making.

学术界和非学术界的加班和工作生活质量：感知工作与生活平衡的作用。

虽然学术工作通常提供很大程度的灵活性，但学者也倾向于加班，这会导致工作与生活的平衡较差。在这项研究中，我们比较了学术人员与非学术人员，并预计学术人员通常会报告较差的工作生活质量，这是对员工整体工作经验的广泛概念化。其次，我们调查了作为学者和工作生活质量变量之间的负面关系是否会因加班而变得更糟，并且是否因工作与生活平衡的看法而有所缓和。我们的样本包括在英国 (UK) 九所高等教育机构 (HEI) 工作的 1474 名学术人员和 1953 名非学术人员。通过结构方程模型分析数据。结果表明，在高等教育机构内，学者报告的工作生活质量往往低于非学术人员，而每周额外工作时间的报告数量较多，这加剧了这种情况。发现员工的工作与生活平衡可以缓和学者（与非学者）在感知工作条件和员工承诺等变量之间的负面关系。我们还发现了曲线关系，即与不加班或加班较多的员工相比，加班达 10 小时的员工对自己的工作和职业更满意，对工作的控制力更强。这些结果扩展了先前的研究，并为学者和非学者之间的工作与生活平衡提供了新的见解，
