What is Michael doing regarding his new promotion?

In this context, the answer that Michael is grumbling about his new promotion suggests he is expressing dissatisfaction or frustration rather than joy or excitement over it. This implies that he may feel overwhelmed by the responsibilities that come with the promotion or may have concerns about the implications it has for his work-life balance or relationships with colleagues.

Choosing this option highlights a more complex emotional response to career advancement, reflecting how some individuals experience stress or anxiety when faced with new challenges rather than viewing it solely as a positive achievement. This nuanced understanding of workplace dynamics illustrates that promotions can evoke a range of feelings, not just happiness or eagerness to celebrate.
