What is the name of your state (only U.S. law)? Illinois My girlfriend works in a customer service position in a casino where she constantly uses a computer while standing. The counter the computer monitor and keyboard sits on is lower than a standard kitchen counter making it uncomfortable to use. Two months ago, my girlfriend developed a severe headache and knot on the back of her neck. The headache has been taken care of, but the neck pain is so severe at times, it causes her to become sick to her stomach. She has missed work a few times, and several times has left work early. She's been to the emergency room twice, an urgent care facility, and now a neurologist who has referred her to physical therapy, but it's not making a difference. The neuro also believes the injury could be caused by her work. I also work at the same casino and know quite well how management there works. If she continues to miss work, or leave early, they will get rid of her. Does she have any legal recourse should they fire her even though her job duties seem to have caused the injury?
