Recently my health has gotten to the point where I need a chair at work (cashier) and I turned in a doctor's note explaining exactly that. My manager calls me and tells me everything about HR investigating me, and what makes me so mad is that everything they're doing is perfectly legal and above board and there's nothing I can do but wait to see what they say. All I asked for is a chair. I'm quitting regardless of if they approve my request or not. They made me fight for this and now they're punishing me for fighting at all. I can't survive in this kind of environment.
