Among the problems that particularly confront a new supervisor in relation to his subordinates, the one which requires the exercise of the most unusual degree of skill and diplomacy is:

• A. changing established ideas
• B. teaching new employees
• C. calling attention to common errors
• D. setting an example

Answer: (A)

Changing established ideas requires an unusually high degree of tact and diplomacy because it disrupts routines, challenges long-held beliefs, and can threaten people’s sense of competence and status. A new supervisor must persuade others to adopt new approaches without triggering defensiveness, while maintaining trust and morale. That requires careful listening, clear rationale, respectful dialogue, and a thoughtful pace that helps people feel involved rather than coerced. Teaching new employees, while important, relies on standard coaching across a stable process. Calling attention to common errors is necessary feedback but can demotivate if not delivered with sensitivity. Setting an example is influential but centers on personal conduct and credibility, not the delicate task of shifting entrenched practices across a team.
