Not really. Employment law in most states is "at will". Either party can part ways, at any time, for any reason or no reason at all. I can quit for no reason, you can fire me for no reason. There's nothing illegal about canning someone just because you'd rather have somebody else do their job. Assuming the OP is in an "at will" state (like the one you live in, by the way): Unless the OP is a member of a protected class AND can prove that they got fired because they are a member of that class, or got fired for some other illegal reason, they're SOL. I don't know the OP, but based on demographics here I'm gonna say he's probably a middle-aged white guy. Definitely not a protected class. Still sucks for the OP, and I'm sympathetic. What I'm not sympathetic to is everyone that wants to sue when life doesn't go their way, or they get their feelings hurt. Huge part of what's wrong these days, IMO.
