本研究專家學者訪談結果指出,職場壓力是難以避免的,僅靠人格特質量表測量、員工自我調適,以預防職場壓力,其實是效果不足的。因此,本研究建議企業雇主及管理階層,尚需遵循相關法令或學習先進國家標竿企業的作法,落實保障員工職場安全,並提供心靈諮詢管道、辦理講座課程、適度調整工作職務,以建立完善的預防措施,減低員工的職場壓力,促使改善員工的身心健康。;The main purpose of this study was to investigate the relationship between the personality traits and the workplace stress of the customer service engineers in semiconductor equipment industry. The goal of this research is expected to be as a reference for the promotion of enterprise care and personnel recruiting in the future. The method adopted in this research includes questionnaire (quantitative) survey of customer service engineers, as well as insight interview (quality) of experts and scholars. The results of statistical analysis of 251 questionnaire survey revealed that the personality traits, included neuroticism, experience openness, and extroversion, were significantly correlated with the workplace stress. In term of job titles, the significance of occupational stress for engineers was higher than that for supervisors. Based on the department attribute, the significance of occupational stress for application engineer was higher than that for hardware and software engineers. In addition, the safety forecast model obtained by regression analysis in this study was Y (workplace pressure) = 0.791 + 0.199X1 (working hours) + 0.359X2 (neuroticism) + 0.250X3 (experience openness) + ε (error). This model indicated that if the employees were working under overtime, overlord, and role conflict without any proper adjustment of their emotions and attitudes, may lead to undesirable regret behaviors. The results of interviews with experts and scholars pointed out that workplace stress is unavoidable. By conducting the questionnaire scale measurement of personality traits and self-adjustment are ineffective to prevent the occupational stress of employees. Consequently, this study suggests that employers and management level should follow the relevant laws and regulations or learn the guideline from the benchmarking enterprises of developed country to implement the protection plans for occupational safety. Furthermore, to establish a sound preventive action for reducing the workplace stress and improving the physical and mental health of employees, the enterprises should provide employee assistance programs (EAPs), held seminars and educational training, and give the appropriate opportunity for job adjustment.
