Final answer:
Muna's frustration and potential resignation appear to stem from excessive paperwork, work overload, and lack of positive feedback, causing feelings of being overburdened and undervalued.
Step-by-step explanation:
The primary reason for Muna's frustration and her threat to resign could be attributed to a variety of factors that are commonly associated with workplace dissatisfaction. Considering the information provided, which includes excessive paperwork, the lack of positive feedback, and a work overload, it seems Muna's frustration may be due to the overwhelming nature of her responsibilities, compounded by a lack of appreciation and support from her supervisors or the organization.
Factors such as an unsafe work environment, frustration with bureaucracy, a sense of overwhelming personal responsibility for clients, or the threat of physical violence also contribute significantly to employee discontent. In the context of a work scenario similar to Muna's, these issues can combine to create a toxic work environment where an employee feels undervalued and overburdened, potentially leading to their decision to contemplate resignation.
