Final answer:
Job mastery leads to control over one's responsibilities, which reduces stress and increases job satisfaction. A strong relationship with one's manager can lead to further opportunities and higher satisfaction levels. Mastery and resilience contribute to one's ability to manage stress and succeed in their career.
Step-by-step explanation:
Mastery of the job and reducing stress have a strong connection, as proficiency in one's role leads to increased control and reduced stress levels. When you know that you are responsible for a particular process and/or outcomes, understanding the expectations set by your manager allows you to focus on meeting those expectations without the added weight of uncertainty.
Your manager is often viewed as your most important internal customer, and providing exceptional customer service to them can result in positive feedback, opportunities for growth, and increased job satisfaction. Control over your job tasks and the belief in your ability to be influential in decisions contribute to a lower vulnerability to stress and greater satisfaction. This is supported by research showing that workers are happiest when they have control over aspects of their work and feel they are part of the decision-making process.
Developing resilience and belief in one's own capacity to succeed despite challenges is essential for career success. Increased proficiency and mastery enable flow states, characterized by deep focus and enjoyment, rather than stress. In summary, control and mastery over one's job significantly decrease stress and increase job satisfaction.
