Is it a right to us fragrances in an office? Or not

It is interesting how companines can come up with so many different scents.  It is also interesting what people like.  And then there is what makes me ill.  I never used to be like this. I loved going in to Bath and Bodyworks and smell all the different scents they have.  But now, I cant.  Certain scents make my chest hurt, and then I get sick to my stomach and if I don't get away from it... now I get really dizzy.  What is really upsetting is I don't know what will set it off.  I do know eucalyptus does and the Fall scents, cedars, pines, and strong spices.  I guess what I want to know is. . . is it a right to use scents in the work place?
