Smoking in the Workplace

A friend of mine started a new job and the owner of the company, who works on the premises periodically, smokes in his office. She is allergic to cigarette smoke due to allergies. The friend complained to her supv. The supv told her he come move her desk and that the owner would not be working at that location much longer. She did not want to move her desk because it would move her away from the team she supervises. The owner has continued to work there. Today she went to HR. The HR person told her that the building was a smoke free building, and he would have to catch the violators in the act. The only person to her knowledge that is smoking is the owner. However, he told her he would have to handle things differently with the owner. He then asked her to bring in her medical documentation that she offered to bring in. Does he have a legal right to ask her to bring this in? Since it is a smoke-free building, shouldn't that be enough.

Is your friend trying to work, or trying to assert her 'rights'? They already suggested a possible accomodation.
If the company is just a tenant in a smoke free building, your friend could try an anonymous tip to the building manager - but I personally rarely act on information received anonymously.
In our shop, we encourage direct feedback. Perhaps a conversation with the owner regarding the smoke allergy situation is in order, but if the owner says - "golly gee that's too bad, perhaps you find work somewhere else" then your friend knows the situation will not change.
Did your friend disclose her allergy in the interview process? If so, then someone dropped the ball.
Smoke free building or not, it seems a bit presumptuous to expect the owner to accomodate someone who has just been hired - resisting the accomodation about the desk move is a losing proposition. Does she expect the owner to relocate? C'mon, be real here.
Good luck!
