The laborer's physical and mental health, well-being, and happiness are among the major indicators for measuring each nation's sustainable development. A conflictive and hostile external environment (war zone) poses considerable difficulty and psychological distress to workers and nonworkers. Therefore, working in such a physically dangerous business environment may hurt worker's well-being and happiness that in turn may reduce the workers' productivity at the workplace. A high level of laborers' productivity in public and private sectors is essential for achieving sustainable development in the long term. Therefore, this paper examines the effects of perceived danger on employees' psychological well-being in war-torn Afghanistan, an issue being addressed for the first time. We tested the moderating role of social support from coworkers on this effect in order to have a broader vision of which individuals are healthier and happier in a physically dangerous working environment. Two survey data sets were collected from 190 employees working in various small private and public businesses in Herat, Afghanistan. Our results reveal the negative impact of perceived danger on employees' psychological well-being and that employees who receive little or no social support from their peers feel the negative effects of a physically dangerous working condition even more acutely.
