fiesta_bhoy, how can anybody give advice on a situation they know nothing about - except very generally, as you did. If the dismissal was unwarrranted then, yes, maybe there's some recourse. But who's to say based on so little information. He's gonna have to find out who's really behind it and what the real situation is, and I doubt that's possible here.
Good luck though, Singleton. I've been in a similar situation, although I resigned just before I was fired or reprimanded because the situation was total bullshit. Still didn't turn out very well for me, but it was just the principle in my case.
At least you can still draw unemployment if necessary (I think). I didn't leave myself that option.
most states are At Will. usually it states somewhere that you can be fired for a good reason or no reason at all. Unless you are discriminated against and can show proof, you have very little to go on. Basically, time to find a new job.
What industry is the job in? What relation is the accusor to you? I'm not a legal expert at all -but perhaps some of this information would help someone in a legal position?
