Thank you for that additional information.
I do not know if your employers will be willing to do what is most likely going to entail a very costly refit in order to change the ventilation of your office just to keep you working for them.
Don't you think it would be easier, and cheaper, for them to fire you and just hire a person without asthma?
If you want a letter I could type up something here and you could print it out and give it to your boss but, to tell you the truth, a letter from your treating physician will carry a lot more weight then anything I could offer you here online.
Does this make sense to you?
Let me know what you would like to do.
