Hi Dr. Grief, I am working part-time in a restaurant with a bad roof (ie....leaking, catching water in pots, buckets, buspans, ect) My manager says the building has been checked for mold and the results came back negative. However, I have personally seen the stuff myself. Roof is bad, leaking, and the ceiling overhead has been wet to the point, it s not only getting water-rings, but it actually falling out. She insists there is no mold. I m terribly sick as of recently. I have lived with arthritis for years and do take a medication to lower my immune system. I m usually in there for four days a week, but have been out since last Sunday, which will be a week tomorrow. I would like your opinion ... how long do I have to remain away for the symptoms to clear up, what are the dangers to my health, and I guess most importantly, what should I do? Thanks for any advise you can offer. Ms. Joyce Morgan
