This document presents a study on the stress levels of coal mine workers in Dhanbad, India. The study had several objectives: to identify the causes of work stress, examine the impact of demographic factors on stress, and analyze the relationship between stress and job outcomes. Several hypotheses were tested. The results identified seven key factors causing stress: time management, compensation, intrinsic factors, empowerment, role overload, and work-life balance. Age was found to impact stress levels, but other demographics did not. High stress was linked to lower job satisfaction, work-life balance, and commitment. The study concludes that work stress negatively impacts workers' efficiency and productivity, and recommends improving working conditions and stress management.
