You're a trader who joined a large investment bank two years ago. Pat, one of your fellow traders, is well known on the Street for being a big risk taker and a big money maker for the firm. Consequently, he is popular among your firm's senior management. You see him at a party one night and notice that he surreptitiously used cocaine several times. Several weeks later in the office, you notice that he seems exceptionally high-spirited and that his pupils are extremely dilated-you know that both are signs of drug use. You're thinking of mentioning something about it to his managing director, Bob, when Pat makes a particularly impressive killing in the market for your firm's own account. Bob jokes that he doesn't know how Pat does it, but he doesn't care. "However he is pulling this off, it's great for the firm," Bob laughs. You feel strongly that this is a problem and that it places your firm at risk. You've already raised the issue to Pat's manager, Bob, who ignored the issue. Do you raise it further? How can you voice your values in this case?
