Social change health education/promotion philosophy

Suppose that you are a proponent of the social change health education/promotion philosophy. What advantage does this philosophy have for the health education specialist that might be a disadvantage for the consumer of health services and education? Defend your answer

You have been hired by a local pharmacy to provide health education/promotion services to customers and employees. Shortly after you begin work, however, you discover that much of your job is marketing nutritional supplements and nonpharmaceutical health-related services provided by the pharmacy and not the health education/promotion you had envisioned. How might this apparent conflict of interest have been avoided?
