A Program on Construction Ethics, 3 Edition CASE STUDY NO.36 Relationships and Questions We are a reinforcing steel fabricator serving primarily general contractors. We offer a discount to our customers for payments received within a certain period after delivery of the reinforced steel. We do this because extended payment periods require that we borrow to cover our cash flow. Relationships Featured Contractor to Vendor Questions 1. Should the supplier continue to do business with the contractor? Our problem is a contractor who feels that the discount can be taken no matter how long it takes them to pay. They always have a reason (excuse) for the late payment; however that does not change the fact that we have to borrow money if they pay late. When we press them for payment they always blow up and accuse us of threatening our ongoing business relationship. The threat of losing their future business forces us to allow the situation to continue. 2. Is it ethical to use buying power to get preferential treatment? 3. What are the ethical considerations involved here? Are these only business decisions
