摘要：The purpose of this study was to investigate character variations and its relationship with occupational fatigue and involvement (labor participation) among employees of Melting unit in Sarcheshmeh Copper Complex. This cross-sectional descriptive-analytical research was carried out on 145 employees of Melting unit in Sarcheshmeh Copper Complex. Sampling method was simple random sampling and data were collected using three standard instruments: anxiety and depression scale (HADS), Swedish job fatigue (SOFI), and labor participation (job involvement). One-way ANOVA, Pearson correlation coefficient and Spearman's correlation coefficient were used to analyze the data using SPSS-24 software. The average age of the subjects was 38 ± 6.94 years and average of their working experience was 10.46 ± 6.73 years. Among the personnel, (76%, n=111) had acute anxiety and (64%, n=93) had mild depression. The mean and standard deviation of job involvement for these subjects was 52.41 ± 7.12 (Desirable situation). There was a significant relationship between all aspects of fatigue, except physical discomfort with job involvement (P 0.05), except for depression with drowsiness. The results indicated that there was acute anxiety, mild depression and high job involvement among the employees of melting unit. It can be significantly reduced in terms of occupational environments and increased job involvement by managing and controlling anxiety by identifying and controlling resources.
