Benjamin is a co-worker of yours. you started working for the same organisation at about the same time and you have always been impressed by his performance. he is friendly and gets along well with everybody. however, recently, things appear to have changed. he is late for work most mornings and although he tends to have an excuse related to his family, often you suspect he is recovering from the effects of alcohol the night before. he puts in good days work, and even with the extra time his work has declined. after he is reprimanded by his supervisor about a report he turned in late, he is very upset.
