## Ethical Dilemma

Herb’s Concoction (and Martha’s Dilemma): The Case of the Deadly Fertilizer[1]

Martha Wang worked in the Consumer Affairs Department of a company called Herb’s Garden Products. Martha was a relatively new employee and had only worked there 6 months, while most employees at Herb’s had been with the company since its beginning back in 1958. She enjoyed her job and hoped to be promoted at her next performance appraisal. One especially exciting part of working at Herb’s was that they had made a public commitment to protecting the environment. There were regular meetings at work about the choice to brand the organization in this way, sell their products at “green” markets, and capture some of the growing consumer market for natural products. Martha’s values were closely aligned with this mentality, so she really loved her new job at Herb’s Garden Products. How quickly things change.

• What kind of decision does Martha face? What are some of her decision-making challenges?
• What recommendations do you have for a company facing this situation? What should they do to deal with this customer complaint? From the perspective of the management at Herb’s Garden Products, what are some next steps that could be taken?

## Group Exercise

Moon Walk and Talk[2]

Warning: Do not discuss this exercise with other members of your class until instructed to do so.

You are a member of the moon space crew originally scheduled to rendezvous with a mother ship on the lighted surface of the moon. Due to mechanical difficulties, however, your ship was forced to land at a spot some 200 miles (320 km) from the rendezvous point. During reentry and landing, much of the equipment aboard was damaged, and because survival depends on reaching the mother ship, the most critical items available must be chosen for the 200-mile (320 km) trip. Please see the list of the 15 items left intact and undamaged after landing. Your task is to rank the items in terms of their importance for your crew to reach the rendezvous point. Place the number 1 by the most important, 2 by the next most important, and so on, with 15 being the least important.
