What is the primary characteristic of burn-out?

The primary characteristic of burnout is that it typically occurs in stages, beginning with enthusiasm for one's work. Initially, individuals may exhibit high levels of energy, commitment, and dedication to their tasks or professional roles. However, as time progresses without adequate breaks or coping mechanisms, they may start to experience stress and fatigue. This progression can even lead to diminished enthusiasm and eventual depersonalization or cynicism regarding their work.

Understanding the stages of burnout is crucial for recognizing the early signs and implementing strategies to prevent it. The concept underscores the importance of self-care and the need for balance in the workplace to maintain long-term well-being and productivity. The other options do not accurately capture the nature of burnout or its progression, thus reinforcing why this particular answer stands out as correct.
