Who are the primary sets of people that affect an individual's job satisfaction?

The correct answer emphasizes the importance of interpersonal relationships in the workplace, particularly between co-workers and supervisors. These relationships significantly influence an individual's job satisfaction.

Co-workers can create a collaborative atmosphere, provide support, and influence work dynamics, which can all enhance job satisfaction. When employees feel connected and supported by their peers, they are likely to experience higher morale and engagement at work.

Similarly, supervisors play a critical role as they are often responsible for providing guidance, feedback, and recognition. A supportive and understanding supervisor can foster a positive work environment, while lack of support can lead to dissatisfaction.

Together, co-workers and supervisors create a social and organizational climate that directly impacts how an employee feels about their job, making this option the most relevant in the context of job satisfaction.
