You posted this on another forum and I asked you several questions there. I only just did it so you haven't had a chance to see them yet. Yes, you were out of line changing the cleaning supplies but that's water under the bridge now.
There is a possible protection for you but it depends on the answers to the questions I asked you over there. I'm going to ask them here, too:
1.) How many employees, overall, does your employer have?
2.) Is there an HR person/office?
3.) Will your doctor certify the reaction you're having to the chemicals?
4.) And one more I didn't think of "down the street" - is this an isolated instance or do you have this same reaction other places? Many years ago I worked for a hotel and we had a frequent guest was allergic to the industrial strength materials we used in our laundry - do you have any other issues?
