The ethics of past mistakes... what would you do?
You are attending a social function with a number of colleagues, many of whom report to you.
In an unguarded moment, one of your colleagues (who has had a little too much to drink) takes you aside. In a clear attempt at confidentiality, he reveals that he made a fairly serious error of judgement in his previous job within the company. However, in a remarkable stroke of good fortune for him, his manager was blamed for his mistake.
