Final answer:
The sales manager can assess Ergun's job satisfaction, stress levels, and work-life balance. Evaluating Ergun's home office ergonomics and the support systems available to him are also crucial in determining psychosocial hazards.
Step-by-step explanation:
To determine whether working from home is a psychosocial hazard for Ergun, his sales manager could evaluate several factors. One method would be to assess Ergun’s job satisfaction, perceived job risk, and stress levels, as these are indicators of psychosocial health as discussed by Sunyal, Ayda, Onur Sunyal, and Fatma Yasin in their 2011 research. Furthermore, communication between Ergun and his manager about work-life balance, observing Ergun's ability to set his own hours while telecommuting, and recognizing any signs of stress related to telecommuting would be beneficial.
In addition, human factors psychology suggests that the ergonomics of Ergun’s home office, such as the height of the chair and desk setup, should be considered to provide an optimal work environment. These ergonomic factors can contribute to or reduce psychological stress. Lastly, the presence of support systems, such as the emotional and practical support from home, and workplace support like having understanding supervisors, could help in reducing work-family conflict which is critical in a telecommuting situation.
