The employee, Hallis, was a recovering drug addict. He had been clean for about a year when he began working for the employer. Initially, things went well but after his supervisors (the brother of the owner) found out about his previous life as an addict, he began picking on Hallis, referring to him as a "crackhead". He called him this both to his face and in emails to other employees. Hallis complained to his employer, but nothing was done. He finally resigned and filed a human rights application, alleging discrimination based on disability, against both the supervisor and the employer. Will Hallis' action against the supervisor likely be successful? Against the employer? Support your answer.
