You are an instructor at a CAF training establishment. You work with another instructor who is very popular amongst the school staff. Very quickly you develop a friendship with this individual.

After several months, you begin to suspect that he has an alcohol-related problem. Although he is never late for work, he always seems exhausted in the mornings and his eyes are often bloodshot. After lunch, his eyes are often glassy and he keeps a large bottle of mouthwash in his desk. Several times, when working late, he was giddy and his breath smelled of alcohol. You approached him, but he denied having a problem.

You decide to let it go, but during a course party, a few trainees recount some stories. They give evidence that, on more than one occasion and after hours, he has appeared at their barracks and engaged in belligerent behaviour towards the individuals that he met in the corridors.

Ethically, what would you do?
