...mold be hazardous to work in? Also, there is no cental air/heat. Is this good or bad. Oh, and the windows don't open (except to fit the A/C units).
No, this question is real. Some of the external stones are black. The tjird floor is condemmed (asbestos floors) and the roof where I work has to peel (can't fix it due to the asbestoes).
Since I started the job in the building I have gotten dermatitis, joint pain, fatigue, migraines, and dizziness. Over the weekend and days off I am fine (except for dermatitis).
How can I prove my ailments are from this working area?

I think it's all good for you, strengthens your constitution.
