To ensure the quality of the work done in the Korean career civil service system (which is characterized by stability, such as lifelong job security), the public sector must use methods to motivate their employees and improve their performance in the long run. In this study, we propose that grit, as a type of work motivation, can boost employee well-being (i.e., job satisfaction, job stress) and organizational outcomes (i.e., organizational commitment, performance). Therefore, the main objective of this study is to assess the validity of grit among public employees from a collectivist culture; to this end, we use the 2016 survey of Korean public officials (N = 2,070). The results are as follows: (a) grit has a direct positive effect on quality of work life (QWL), (b) QWL can increase employee’s quality of life (QOL), and (c) professionalism and goal-oriented culture negatively and positively regulate grit and QWL. We also examined how employee motivation (e.g., grit) can enrich their QWL and QOL. Altogether, this study supports the argument that human resource (HR) managers should pay attention to grit. To achieve success, one needs not only some level of ability but also the zeal and capacity for hard labor, the latter two of which are considered to constitute grit. Given that, this research targeted grit in the Korean context—not the Western one—and examined its effects in the Korean public sector, where conscientiousness is emphasized.

为了确保韩国职业公务员系统的工作质量（以稳定为特征，例如终生的工作安全），公共部门必须使用各种方法来激励员工并从长远来看提高他们的绩效。在这项研究中，我们建议将勇气作为一种工作动机，可以促进员工的福祉（即工作满意度，工作压力）和组织成果（即组织承诺，绩效）。因此，本研究的主要目的是评估集体主义文化中公职人员的毅力有效性。为此，我们使用了2016年对韩国公职人员的调查（N= 2,070）。结果如下：（a）毅力对工作生活质量（QWL）有直接的积极影响；（b）QWL可以提高员工的生活质量（QOL）；以及（c）敬业精神和目标导向的文化产生负面影响；积极调节砂砾和QWL。我们还研究了员工的积极性（例如毅力）如何丰富他们的QWL和QOL。总而言之，本研究支持以下观点，即人力资源经理应注意勇气。为了获得成功，一个人不仅需要一定水平的能力，而且还需要辛勤工作的热情和能力，后两者被认为是坚韧不拔的。鉴于此，这项研究针对的是韩国背景下的砂砾，而不是西方国家的砂砾，并研究了其在韩国公共部门的影响，强调了责任心。
