Further to my previous post, we had several pilots in my company who had been treated successfully for alcoholism and who continued their careers with distinction. When the management heard rumours that a pilot was suffering from a drinking problem one of the ploys was to manipulate the roster so that the successfuly treated pilot was teamed up with the suspect alcoholic without the suspect knowing that that had been done. This created the opportunity to discuss the company policy and how he/she could be helped. Sometimes there was a positive outcome.
