Listen, I am not a lawyer so thats why I said what I did when I originally posted. Think about the effects. I am not trying to thread jack but this is kinda killing me.
I have a real career, so I have real HR policies and standard that I have to read/sign etc. Functionally, the boss will probably have the upper hand as far as getting rid of an employer. However, you went to the hospital. That *might* be a defensible position as far as it not being a firing offense. At-will employment is not as raze-the-forest all encompassing as you guys think. Even in your at-will employment article you cited, there is a "Good-Faith..." clause. Granted, he is not in a Good-Faith and Fair Dealing state, but I am just saying there are a lot of lawyers out there that make a living getting bullshit like this thrown out.
