The improvement in skill and the development of proper attitudes are essential factors in building correct work habits. Which of the following is the most valid implication for a supervisor?

• A. The improvement in a worker's skill is the only part of the supervisor's job.
• B. Developing proper attitudes in subordinates toward their work is more time-consuming for the supervisor than improving their skill.
• C. The improvement of a worker's skill is only part of the supervisor's job.
• D. Correct work habits are established in order to either improve the skill of workers or develop in them a proper attitude toward their work.

Answer: (C)

Building correct work habits requires attention to both skill development and the cultivation of proper attitudes. A supervisor must guide and support both aspects, not just technical improvement. Therefore, saying that improving a worker’s skill is only part of the supervisor’s job correctly captures the idea that attitude development also belongs to that role. The other options misstate the scope or the relationship between skill and attitude: claiming it’s the only part ignores attitude work; claiming attitude development is more time-consuming isn’t supported by the given idea; and treating the goals as an either/or choice misrepresents how both elements work together to form good habits.
