眼鏡業從業人員工作滿意度對工作績效之影響──以工作投入為中介變項

The Impact of Job Satisfaction on Job Performance among Optical Industry Employees: The Mediating Role of Work Engagement

驗光人員法案在105年1月6日公布施行，眼鏡業從業人員須通過國家級專業證照成為第十五類醫事人員為驗光人員（驗光師和驗光生）。眼鏡業從業人員面臨長時間及高壓的工作環境，如何提升工作投入與滿意度，改善工作績效，已成為重要議題，然而針對眼鏡產業的相關研究仍較為缺乏。本研究探討在驗光人員法通過後，驗光人員從事門市服務人員成為醫事人員後，對其工作投入、工作滿意度與工作績效之影響與各構面之間的關聯性，進一步探討工作投入對於工作滿意度與工作績效是否具有中介效果；最後，針對不同人口統計變數探討其對工作投入、工作滿意度以及工作績效之影響。研究對象為在職驗光師與驗光生，透過問卷收集312份問卷，有效問卷為305份，以敘述性統計分析、迴歸分析以及變異數分析檢驗研究假說。研究結果如下：（一）眼鏡業從業人員之工作滿意度對工作績效呈顯著正向關係。（二）眼鏡業從業人員之工作滿意度對工作投入呈顯著正向關係。（三）眼鏡業從業人員之工作投入對工作績效呈顯著正向關係。（四）工作投入對工作滿意度及工作績效的具部分中介效果。（五）高學歷且在眼鏡業從事21年以上的資深從業人員，對工作滿意度、工作投入及工作績效的認同度顯著高於其他從業者。根據研究結果為眼鏡產業經營者提供具體建議，以提高員工的工作投入與滿意度，進而提升工作績效，達到企業與員工雙贏的目標。

The Optometrist Personnel Act was officially implemented on January 6, 2016. Optical industry employees are required to pass the national professional certification to become the 15th category of medical personnel, classified as optometrist personnel (optometrists and optician trainees). Optical industry employees face long working hours and high-pressure environments, making it crucial to improve work engagement, job satisfaction, and job performance. However, there is a lack of research specifically focusing on this industry. This study e×plores the impact of the Optometrist Personnel Act on work engagement, job satisfaction, and job performance among optical industry employees after becoming medical personnel. It further investigates whether work engagement plays a mediating role between job satisfaction and job performance. Additionally, the study e×amines how various demographic variables influence work engagement, job satisfaction, and job performance. The research targeted active optometrists and optician trainees, collecting data through a questionnaire. A total of 312 questionnaires were distributed, with 305 valid responses collected. Descriptive statistical analysis, regression analysis, and analysis of variance (ANOVA) were used to test the hypotheses and e×amine the differences. The key findings of the study are as follows: (1) Job satisfaction among optical industry employees has a significant positive impact on job performance. (2) Job satisfaction has a significant positive impact on work engagement. (3) Work engagement has a significant positive impact on job performance. (4) Work engagement partially mediates the relationship between job satisfaction and job performance. (5) Employees with higher education and more than 21 years of e×perience in the optical industry demonstrate significantly higher recognition of job satisfaction, work engagement, and job performance compared to other groups. Based on these findings, the study provides practical recommendations for optical industry managers to enhance employees' work engagement and job satisfaction, thereby improving job performance and achieving a win-win outcome for both companies and employees.
