The purpose of this study was to investigate the relationship between mindfulness and coping strategies with working memory in employees of Shirvan's combined cycle power plant. The statistical society consisted of all employees of the gas and steam sectors of Shirvan CCPP (700 people). According to Krejcie and Morgan table, the research samples were 248 people, which have been selected accidentally. The research method was descriptive and correlational, that has been conducted in the form of field. The data collection tool in this research was a four-pages questionnaire with 108 questions, including three standard questionnaires on Mindfulness of Baer et al (2006), coping strategies of Lazarus and Folkman (1984), and Daneman and Carpenter's (1980) working memory. Furthermore, the descriptive and inferential statistical methods (Kolmogorov-Smirnov, Spearman correlation coefficient at a significant level of P <0.05 and simple linear regression) were used for data analysis and also Smart PLS software has been used to survey the mediating role of coping strategies in the relationship between mindfulness and working memory. The results indicated that there is a significant relationship between mindfulness and problem-based/emotion-based coping strategies with the working memory of power plant's staffs. In addition, mindfulness and problem-based/emotion-based coping strategies have the ability to predict the working memory of employees. Besides, the results showed that coping strategies play a mediator role in the relationship between mindfulness and working memory. With respect to the research findings, human resources managers of Shirvan CCPP are suggested to improve the personnel's working memory by holding the mindfulness and coping strategies training courses.
