AMC Theatres review: Discrimination

So I just started working at AMC THEATERS like 2 weeks ago upon Hiring I let them know I had a disorder and they were fine with it I have a sleeping disorder specifically call Narcolepsy but it's accompanied by cataplexy thi gs are going good u till I fell asleep in the break room a couple of nights ago then that day I received 1 write up about it the next day everyone is treating bad and ignoring me but regardless I'm happy person so I continue with my own business a lady comes up yelling in my face about a ticket my supervisor gave her that was past showtime on my screen I couldn't handle it so I let my shift leader get her and then the next day I'm fired they started treating me different ever since I told them about my disorder and got it in writing from my doctor and also they over heard a convo between me and my brother about me being able to go to sleep if I need to bc of my disorder and all especially since they had the paper saying that's what would happen ever since I gave them that official paper they started getting me for little things I received no warning about other complaints because everyone loves me so I don't understand why I'm fired for.something so insolent when I did nothing g wrong I let someone else handle it
