Final answer:
An employee talking more quickly and loudly often signifies frustration. Melancholy is not one of the seven universal emotions; work content is a strong predictor of job satisfaction. When a businessman sees hard work as its own reward, it reflects a stoic viewpoint or reconciling with dissatisfaction.
Step-by-step explanation:
An employee who begins to talk more quickly and loudly in response to a customer's questions is likely communicating frustration. This change in tone and speech pace can indicate that the employee is experiencing difficulty in addressing the customer's issues or queries, leading to a build-up of stress and irritation.
Examining universal emotions, melancholy is not listed as one of the seven universal emotions described in typical psychological literature, which commonly includes contempt, disgust, anger, along with others like happiness, sadness, surprise, and fear. As for job satisfaction, studies have shown that work content is a more predictive factor of overall job satisfaction than financial rewards, personality, or autonomy. This is due to the fulfillment employees feel when they find their work meaningful and engaging.
In the context provided, a businessman who comforts himself with the idea that hard work is its own reward is likely dealing with feelings of dissatisfaction regarding his financial situation, but is trying to align his values with his current circumstances, perhaps reflecting a stoic approach to his work life.
