Measuring and determining the components of quality of work life is one of the most important concerns of human resource management. This study examines the relationship between quality of work life with musculoskeletal disorders (MSDs) and hearing loss as indicators of HSE in an automobile manufacturing company. The statistical population of this descriptive-analytical study consists of 392 employees of company who were randomly selected from different departments using Morgan table. Required data was collected using an improved NIOSH quality of work life questionnaire, body map and audiogram. SPSS software (version 23) was employed for descriptive and regression analyses. All stages of this research were conducted ethically. The findings showed that the mean score for quality of work life was 171.13, ranging from 101 to 212. The greatest sensation of pain, based on the results, was at the end of the lumbar region with a frequency of 40.31 percent and the least was reported in palm left hand with a frequency of 6.38 percent. Furthermore, 6.3% of respondents showed hearing disability. Statistical analyses showed that there is significant relationship between the quality of work life and musculoskeletal diseases (p = 0.000) as well as the quality of work life and the rates of hearing loss (p = 0.000). Also, statistically significant relationship were noticed between the quality of working life and the level of health and safety, mental health, physical health, and employment in a noisy environment . If correct management issues of quality of work life were implemented, improved health indicators and subsequently improved quality of work life could be seen in an organization.
