Re: We are All All of these.
True, but that being said, a person's illness is not a protected class against discrimination. Only certified disabilities are. And it is hard for the layman to distinguish between Cystic Fibrosis, and Tuberculosis, for which OSHA now requires safetly posters to be displayed in the workplace. So, someone's chronic coughing could be grounds for dismissal, with the company having legal grounds to protect its workers and workplace. The "cougher" would have no recourse, unless it was a work-related injury, which is doubtful.
