Please write a 350 to 600 word essay in response to this prompt.

You are 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 ?rm. Consequently, he is popular among your ?rm's senior management. You see him at a party one night and notice him surreptitiously using cocaine several times. Several weeks later in the of?ce, 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 are thinking of mentioning something about it to his managing director, Bob, when Pat makes a particularly impressive killing in the market for your ?rm's own account. Bob jokes that he does not know how Pat does it, but he does not care. ‘‘However he is pulling this off, it's great for the ?rm,'' Bob laughs. You feel strongly that this is a problem and that it places your ?rm at risk. You have already raised the issue with Pat's manager, Bob, who ignored it. Do you raise it further? How can you voice your values in this case?
