In all symptoms associated with fatigue average score of rotating-shift were higher than dayshift and there was a significant difference between them. Relationship between the symptoms of fatigue with Insomnia Severity Index was significant. Warehousing received the highest scores of fatigue and severity of insomnia between different tasks under study.
