Which term refers to a state of feeling unhappy or dissatisfied with one’s job?

The term that specifically refers to a state of feeling unhappy or dissatisfied with one’s job is "disgruntled." This word encompasses a sense of resentment or dissatisfaction particularly in a work context. When individuals feel disgruntled, it often stems from specific grievances related to their employment, such as working conditions, management decisions, or unfair treatment.

While "discontent," "unhappiness," and "frustration" can also describe negative feelings, they are broader terms that don't necessarily pertain exclusively to one's job. "Discontent" implies a general lack of satisfaction but can apply to various aspects of life beyond employment. "Unhappiness" is a more generic term for emotional state and does not indicate any specific origin for those feelings. "Frustration" often relates to feelings of annoyance due to inability to achieve goals and may not be directly tied to job dissatisfaction. Thus, "disgruntled" is the most accurate choice in the context of job-related dissatisfaction.
