One is questionnaire to verify macro ergonomic situation which planned and consisted of 30 questions that investigated different factors in working environment and was verified in terms of stability and reliability (cronbach alpha = 0.72) and the other one was Minnesota job satisfaction questionnaire which was distributed among people. Results This research shows over 1,500 extended hour's male workers, 69 percent of whom reported "Chronic or Frequent" back pain, while 52 percent reported "Chronic or Frequent" wrist pain. Sleep deprivation could possibly be damaging in terms of muscle, ligament, or tendon injury. With the average extended-hours employee sleeping only 5.1 hours to 5.5 hours each day when working a night shift, they could face an increased risk of ergonomic injuries. The mean age of people under investigation is 30.8. Most people are in age group of 26-30 (44.6%) most individuals have 4 to 7 years working experience (56.6%). Macro ergonomic mean score in total society under study was obtained as 59.8. The highest score of job satisfaction has been related to middle managers (69.2). Pearson correlation test showed that there was a direct relationship between general domain of macro ergonomic and job satisfaction. Conclusion There is a consistency between main enhanced results in our study in terms of macro ergonomic situation with the result of similar studies of barariyan (2006) and rajabzadeh (2002) that have used RSI (Relative Stress Index). Also there is a correlation between the result of our study job satisfaction with the results of similar studies such as Bassy's (2002) in Swedish employees , Garcia and Molina's (1999) in Spanish employees and the result of Partovi study (2006) in Esfahan steel plant employees and Davari's (2003) in employees of Esfahan Shahid PowerStation.
