Guess what, the employer is not allowed to fire you for this that I suggest that you take it to the proper people in your state. It was improper for him not to tell you that there was asbestos in the building. He was supposed to give you the gear while you working with the stuff. Yes, you have a legitimate case. I hope you told the doctors at the hospital about this. Don’t forget to make copies of what you have when taking it to whom ever you take it too. I wish you all the luck
