Final answer:
Mastery of the job reduces stress by giving a salesperson a greater sense of control, which is linked to lower stress and greater job satisfaction. However, using metacognition to manage emotions is also important, indicating control alone doesn't eliminate stress.
Step-by-step explanation:
The answer to the question is false. Mastery of the job can indeed reduce feelings of stress because it can provide the salesperson with a greater sense of control over the work environment. This sense of control may mitigate the impact of potential stressors. Albert Bandura has indicated that stress is affected by the perceived control over life's demands. Additionally, research suggests that when workers feel they are part of the decision-making process, have freedom from constant surveillance, and feel integral to the outcome of their work, job satisfaction increases. A salesperson who masters their job would likely experience these conditions and therefore, a lower level of stress. However, it is also true that using metacognition to reflect on and manage emotions can be necessary to respond to strong emotions effectively, demonstrating that control isn't the only factor in stress management.
